Abstract

A carbon fuel combustion supporting packaging, which provides a packaging that assists ignition of carbon fuel internally packed therein. The present invention includes a combustible bottom frame, on an upper end opening of which is located a combustible fire grate that separates an upper holding space for loading the carbon fuel and a lower raised space for placement of a kindling therein. After ignition, tiny flames first leap up and burn the combustible fire grate, whereupon combustion of the fire grate converts the tiny flames into a substantially large thermal power and an expansive area of flames which assist in effecting a comprehensive ignition of the upper carbon fuel. After complete combustion, a combustible enclosing body joined to an upper end opening of the bottom frame, and which also packages the carbon fuel, is simultaneously burnt along with the carbon fuel.

Description

BACKGROUND OF THE INVENTION

(a) Field of the Invention
The present invention relates to a carbon fuel combustion supporting packaging, and more particularly to a carbon fuel combustion supporting packaging able to provide initial ignition of internal packaged carbon fuel, and assist actuating overall ignition of the loaded carbon fuel. Moreover, the combustion ashes can serve as an organic fertilizer compound, thereby avoiding secondary pollution.
(b) Description of the Prior Art
Regarding general application of carbon fuel, such as charcoal or coke, and so on, being used as a fire source, in general, carbon fuel serves to provide required heat source when barbecuing. Normal application uses a large sealed package of carbon fuel, and procedure involves removing a portion of the carbon fuel from the package of carbon fuel according to needs, which is then disposed within a metallic stove body 100, as depicted in FIG. 1.
The metallic stove body 100 is primarily structured from a metallic fire grate 102 separating a bottom space and an upper portion holding space. The upper portion holding space enables carbon fuel 4 to be laid therein. A grill 101 spans and is disposed atop end hole, and the bottom portion is supported by a tray 103.
Ignition operation includes disposition of the metallic fire grate 102 to separate a raised space in the bottom portion of the stove 100, and flames leaping from a combustion device 104 leap up towards a bottom portion of the carbon fuel 4 disposed in the upper level, and after ignition, the combustion device 104 is moved away.
Or ends of fuses 105 are pushed through to within the carbon fuel 4, and after igniting the outward facing ends of the fuses 105 the fuses 105 progressively burn into overlapping interspaces of the carbon fuel 4, thereafter forming sources of ignition to enkindle the carbon fuel 4. After complete combustion, ashes drop into the tray 103.
The carbon fuel 4 is packaged in a large bag, and the carbon fuel must be taken out and apportioned into required amounts, which are then distributed within the metallic stove body 100. However, it is difficult for a user to avoid contaminating his hands or clothes during such a procedure. Moreover, the metallic fire grate 102 becomes deformed and defiled after prolonged heating, and is difficult to clean after retrieving to reuse. Hence, the metallic fire grate 102 is often discarded, resulting in environmental pollution.
The aforementioned metallic stove body 100 enables assisting effective combustion of the carbon fuel 4. However, when used without the stove body 100, the carbon fuel 4 can only be stacked on top of the tray 103, and the fuses 105 are then directly disposed at a bottom portion of the stacked carbon fuel 4 to effect enkindling thereof. During the course of ignition, ignition frequently fails because of oxygen deficit factors, or when in open country, and in a situation whereby only the carbon fuel 4 is prepared, then the carbon fuel 4 is stacked directly on the ground and ignited, and apart from using the fuses 105 for the ignition operation, the combustion device 104 can also be used to ignite and burn the carbon fuel 4.
However, such prior art methods are extremely troublesome, and because the carbon fuel 4 is a carbon compound that easily decomposes or micro particles break away, thereby causing pollution. Moreover, portability function of this prior art is extremely inconvenient.
Referring to FIG. 2, which shows a precombustion bucket 107, which is designed as a collective whereby after the carbon fuel 4 has been ignited, it is distributed for use in multiple grills. A bottom portion of the girth of the precombustion bucket 107 is separated using a mesh 108, and the combustion device 104 is disposed beneath the mesh 108 to produce flames that leap up towards the carbon fuel 4 disposed on the mesh 108. Hence, flames leaping up from the combustion device 104 or any other method that enables flames to leap upward towards the upper carbon fuel 4, cause the carbon fuel 4 to form a self-ignition state, whereafter the carbon fuel 4 can be allocated to a barbecue stove for use thereof. After ignition, the precombustion bucket 107 itself is heated to a high temperature, thus, an elongated handle 109 is used to carry the precombustion bucket 107 and empty out the carbon fuel 4. Such an ignition method, along with the aforementioned method, is similarly extremely inconvenient.
Referring to FIG. 3, which shows an improvement using a grid-type case 106, and after the carbon fuel 4 is disposed therein, the fuses 105 are inwardly penetrated into the interspaces of the carbon fuel 4. After igniting the fuses 105, flames slowly enkindle the carbon fuel 4 in contact with the fuses 105, thereby causing the production of sufficient heat for self-ignition to occur. The grid-type case 106 is made from combustible material which burns to form ashes, and enables packaging the carbon fuel 4 in advance, whereby the grid-type case 106 being a box-type body enables the carbon fuel 4 to be disposed within the entire interior. However, oxygen for combustion is only able to enter from side directions, and the fuses 105 are simply used to ignite and form flames, thus thermal power is inadequate. Moreover, the fuses 105 are unable to be comprehensively distributed, to affect total ignition.
A state is often seen whereby a portion of the carbon fuel 4 undergoes excessive combustion burnt, whereas a portion is unable to be ignited, and the carbon fuel 4 positioned center of the bottom portion never undergoes synchronous combustion. Time from the start of ignition to total combustion takes approximately 30 minutes; however, stages of mutual combustion of the granular carbon fuel 4 are unable to coincide. Some portions are overheated, whereas some portions are cold, and the cold carbon fuel 4 will absorb heat from the relatively hotter carbon fuel 4 when used in a barbecue, thereby causing a considerable reduction in heat output used to barbecue, and the formation of a substantially low temperature state, a consequence of which is lengthening of the heat power time and dispersal thereof, resulting in a heat temperature absorbed by food material being inadequate, and thus heat grilling time must be extended.

SUMMARY OF THE INVENTION

A primary objective of the present invention is to provide a carbon fuel combustion supporting packaging which effectively supports combustion to enable comprehensive synchronous burning of carbon fuel, and facilitates cleanliness when carrying. The present invention comprises a bottom frame, an upper end opening of which is joined to an enclosing body that simultaneously packages the carbon fuel. The bottom frame includes a combustible grid-type fire grate that separates a raised space to enable a kindling to be disposed therein. The present invention further uses a two-stage ignition method to effectively realize uniform ignition and burning of the carbon fuel loaded within the enclosing body.
A second objective of the present invention is to enable the enclosing body to be joined atop the bottom frame to achieve enabling packing the carbon fuel therein. The enclosing body can be simultaneously burnt along with the carbon fuel to form ash material.
A third objective of the present invention is to enable the bottom frame or the enclosing body to be formed from molded combustible fiber material.
A fourth objective of the present invention is to use plant carbon, as the carbon fuel, whereby wood chips or plant fiber is molded to form standardized shapes to facilitate arrangement of the carbon fuel in rows and thereby form flame and fume passageways.
A fifth objective of the present invention is to use an interlayer method to distribute upper and lower layers of carbon fuel, and the kindling is disposed in a girth portion, thereby enabling the kindling to first burn the upper layer carbon fuel, and heat waves transmitted downward then ignite the carbon fuel of the lower layer, and use of a rising air current flow effect enables effecting double-step combustion of the carbon fuel, moreover, heat output obtained is of relatively uniform value according to extended combustion period acquired.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 4, which shows a three-dimensional schematic view of the present invention, comprising a packing body 10 primarily structured from a bottom frame 20 joined to an enclosing body 1. The packing body 10 comprising the combustible bottom frame 20, a periphery of which comprises enclosing boards 221, 222, 223, 224, which are structured as an enclosure to form lateral windbreaks, and an upper end opening is upwardly separately by combustible grid-type fire grates 2. An upper end of the bottom frame 20 is joined to the combustible enclosing body 1, and the combustible enclosing body 1 is formed by interlocking a plurality of combustible rod members 15, thereby forming a plurality of through holes 12 in the periphery of the enclosing body 1.
The enclosing body 1 located on the upper end of the bottom frame 20 shapes a holding space 11, and the bottom frame 20 forms a raised space H which enables a kindling 3 to be disposed therein.
The grid-type fire grates 2 are arranged in parallel, and form lateral ventilation through holes 21 that enable required air to be supplied to the related interior space H. Because size of the kindling 3 is relatively tiny, thus, air requirements for combustion rely on the through holes 21 to laterally replenish a sufficient amount of air.
In actual use, the kindling 3 can be combustible solid alcohol, a periphery of which can be wrapped and sealed using an enveloping body 31. The enveloping body 31 is airtight under normal conditions, that is, an organic gas is unable to leak out, can be stored for a long period of time and facilitates safe carrying.
Furthermore, the kindling 3 can be kindling formed by mixing wood chips with mineral oil, and a periphery of the granular kindling is then enwrapped using paper. The paper can be oil-based, which can be pre-ignited, thereafter igniting the wood chips, whereupon the mineral oil assists in achieving rapid combustion.
The packing body 10 is structured from an interlocking of a plurality of the woody plant combustible rod members 15 to form the enclosing body 1 and the bottom frame 20, wherein the rod members 15 can be formed from wood material or wood-based pressed-fiber boards or material segmented from a tree trunk or bamboo rods or structured from carved up bamboo combs.
The aforementioned bottom frame 20 or the enclosing body 1 can be further formed by molding and slicing, such as wood chip fiber or plant fiber molded into shape through combined molding to form grid-type boards (not shown in the drawings), whereafter the grid-type boards are structured as an enclosure to form the enclosing body 1 or the bottom frame 20. A similar molding method can be used to fabricate the fire grates 2 as an integrated body and form a grid-type shape.
The aforementioned rod members 15 are obtained by slicing wood fiberboards, and then material of accurate dimensions is obtained by sectioning the fiberboards to facilitate feeding to an automatic production line, machine tools or a machine arm for precise positioning thereof according to requirements.
The enclosing body 1 can be further structured using any material, such as cardboard refabricated from waste paper, objective being to achieve a configuration that provides a lateral distribution of the air through holes 12, moreover, the material must be combustible and able to completely burn along with the interior fuel.
Referring to FIG. 5, which shows the packing body 10 structured from the bottom frame 20 and the enclosing body 1 joined to the top end thereof. Interior of the enclosing body 1 forms the holding space 11 that enables the carbon fuel 4 to be disposed therein. Interior of the bottom frame 20 enables the kindling 3 to be disposed therein. The packing body 10 is directly disposed on a tray or the ground, and a combustible fiber material carry rope 50 is joined to the upper end opening, which enables carrying the packing body 10 and is able to be burned.
Ignition operation involves first igniting the kindling 3, whereupon flames initially leap up towards the combustible fire grates 2. A much greater thermal power is then created after the combustible fire grates 2 are ignited, which flares up towards the bottom layer of the carbon fuel 4 positioned above the fire grates 2. Because of the grid-type surface of the fire grates 2, after ignition, flames cover the entire fire grate 2, thereby providing an equivalent expansive area of flames that leap up and completely flame the bottom layer of carbon fuel 4 positioned above thereof.
At the start of ignition, air Al at a bottom portion enters the through holes 21 formed by spacing of the fire grate 2 and supplies needed air for the kindling 3. After the carbon fuel 4 has ignited, air enters through the through holes 12 or 13 to supply oxygen to the burning carbon 4, and the carbon fuel 4 from the bottom portion upwards successively ignites to achieve comprehensive ignition of the entire carbon fuel 4. During the course of ignition, because flames from the kindling 3 first ignite the lower fire grate 2, thus, such a situation might result in the fire grate 2 caving in due to it complete combustion thereof, a consequence of which results in the upper supported carbon fuel 4 falling down. However, a precondition for the carbon fuel 4 to fall down is that the fire grate 2 be completely burnt and fragmented, thereby causing the fire grate 2 to lose its structural mechanical strength before caving in. This being the case, the fire grate 2 being completely burnt already indicates that a corresponding sufficient thermal power has been supplied to ignite the bottom layer of carbon fuel 4, thereby enabling the carbon fuel 4 to achieve a self-ignition state, indicating that the carbon fuel 4 no longer needs the bottom portion flames. After falling down, the carbon fuel 4 is similarly able to implement self ignition, and flames produced upwardly flame the upper stacked carbon fuel 4.
During the course of ignition, the rod members 15 structured as an enclosure to form the enclosing body 1 are similarly burnt by flames leaping out the through holes 12. During the latter half of the period of burning, the rod members 15 are ignited and completely burnt, resulting in the rod members 15 caving in, and the residual ash from the caved-in rod members 15 becomes mixed with a periphery of the stacked carbon fuel 4 and burnt along therewith. Moreover, heat radiation from the carbon fuel 4 after caving in of the rod members 15 Is similarly able to flame the bottom portion rod members 15, thereby resulting in comprehensive burning of the entire structure.
Regarding the amount of air supply after caving in, oxygen source of the center portion of the residual ash formed from the caved-in carbon fuel 4 is mixed with the rod members 15 is primarily supplied by the already ignited carbon fuel 4 of the center bottom portion, and air flow speed increases because of heat temperature. Under high temperature conditions, air flow speed and oxygen consumption increases, which flows a vacuum force that sucks in outer peripheral oxygen into the center through interspaces to assist burning of the center portion. Even a smoldering process is similarly able to produce an assisting air supply to realize the aforementioned burning effect.
The aforementioned rod members 15 being the structural source material for the enclosing body 1 or the bottom frame 20, an agglutination or nailing method can be used as the interlocking means between the interlocked rod members 15. If the nailing method is used, then required specifications of the nails used is that they must be easily and quickly oxidized by heat from the carbon fuel 4 or be made of hot-melt material. If fine nails having cross-sectional diameter of approximately 0.3 mm are used, experimental results show that after complete combustion together with the carbon fuel 4, then the aforementioned iron nails are heat fused and form minute irregular fused grains containing a large amount of foreign material, which easily decomposes to ferric oxide when combined with soil, and the ferric oxide can be used as a component of organic fertilizer.
The aforementioned nailing method is the preferred means to structurally assemble the present invention, because, first, it does not cause any environmental pollution problems, and, second, it facilitates production assembly and fixing of the structural configuration.
After the aforementioned nails have been nailed into the rod members 15, consideration must be given to problems of oxidization due to humidity, thus, a surface of the nails must be provided with an anti-oxidization layer, such as an electroplated layer, for instance, nails used in decoration, then the aforementioned specifications and plated film of anti-oxidization layer satisfy the requirements to provide adequate protection.
Referring to FIG. 6, which shows a schematic view of an embodiment of the present invention in use, wherein the packing body 10 is being used in open country, and stones or bricks 61 are stacked high directly on a ground 6 to form a raised support, on top of which a utensil can be directly disposed for heating thereof, such as a pot, a pan utensil supported by a grate, or a barbecue grill 101. The procedure for igniting involves first igniting the kindling 3, which subsequently burns the combustible fire grate 2, whereafter procedure for ignition and burning of the carbon fuel 4 is as depicted in FIG. 5.
The primary concept of the present invention is the use of the enclosing body 1 joined atop the combustible bottom frame 20 to form the packing body 10, interior of which simultaneously contains the carbon fuel 4, thereby facilitating portability, ignition and combustion. Residual ashes after combustion can be released to the ground 6 to form an organic fertilizer. FIG. 7 depicts the simultaneous packaging concept of the carbon fuel 4 within the packing body 10.
Packaging configuration of the present invention is directed towards the carbon fuel 4 packaged within the holding space 11, whereby the carbon fuel 4 is first indirectly wrapped and sealed using a paper bag 5, wherein objective of the sealed wrapping is to avoid tainting by granules from the carbon fuel 4 when carrying the packing body 10, thereby ensuring cleanliness when carrying the present invention.
After using the paper bag 5 to wrap and seal the carbon fuel 4, any sealing method can be adopted as a seal 51 to seal an opening of the paper bag 5, such as adhesive, or use of the carry rope 50 to bind the opening. Regardless of whether an adhesive method or a binding method using the carry rope 50 is adopted, the present invention adopts the same binding concept, that is, the adhesive or the carry rope 50 is binds position of the seal 51 and then extended and fixedly joined to an upper end opening 14 of the enclosing body 1. Such a concept enables using mechanical strength of the upper end opening 14 to simultaneously fix the paper bag 5, thereby ensuring the paper bag 5 remains within the holding space 11 during the course of carrying. Moreover, purpose of using the natural carry rope 50 is that it is a natural material which does not cause pollution after combustion.
The kindling 3 used by the present invention can be further placed at an uppermost position within the paper bag 5 and wrapped and sealed together with the carbon fuel 4. When it is desired to use the present invention, the seal 51 is opened and the kindling 3, being at the uppermost position of the paper bag 5, can be readily taken out of the paper bag 5, whereafter the kindling 3 is disposed within the raised space H. After the kindling 3 is ignited, flames first leap up towards the combustible fire grate 2, as depicted in FIG. 5, whereupon the paper bag 5 is ignited, and adequate thermal power enables ignition and incineration of the carbon fuel 4 within the paper bag 5.
The paper bag 5 can also be fabricated from inflammable material that rapidly burns upon coming in contact with a low temperature flame. As long as the enwrapped carbon fuel 4 comes in contact with a raised temperature, then surface area of the paper bag 5 in close contact with the carbon fuel 4 first burns, thereby causing holes to appear in the burning paper bag 5 which enable air to enter.
Another embodiment of the present invention involves first taking out the kindling 3 from the opened paper bag 5, and then emptying out the carbon fuel 4 contained within the paper bag 5. The carbon fuel 4 is then disposed within the packing body 10, as depicted in FIG. 5, thereby eliminating consideration of the burning process of the paper bag 5.
Apart from using the paper bag 5 to enwrap and seal the carbon fuel 4 or enwrap and seal the carbon fuel 4 together with the kindling 3, the present invention can also use packaging such as paper or plastic film, a plastic bag, and so on, to implement direct or secondary packaging of a periphery of the packing body 10.
The bottom frame 20 of the present invention can be independently formed, and joined to the corresponding independent enclosing body 1, or the bottom frame 20 and the enclosing body I can be conjoined by co-structured means. If the bottom frame 20 and the enclosing body 1 are independently fabricated, then material for each can be specifically selected according to combustion speed requirements, or the material can be selected based on economic conditions, and specifications of the carbon fuel 4 used can be chosen according to different conditions.
FIG. 8 depicts an application of the present invention, wherein the packing body 10 is primarily structured from the bottom frame 20 and the enclosing body 1 joined atop thereof. The upper end opening of the bottom frame 20 is spaced at intervals using the grid-type fire grate 2, and the grid-type fire grate 2 is mutually connected to the enclosing body 1 located thereon, thereby forming the holding space 11 which enables the carbon fuel 4 to be disposed therein. The enclosing body 1 is structured from a plurality of rod members 151, 152, 153, and dimensions of the rod members 151, 152, 153 in each section of the enclosing body 1 can be different to effect variation in combustion duration, for example, height of the lower rod members 151 is greater than height of the upper rod members 153. Reason for such a size-variation configuration of the rod members 151, 152, 153 is that because flames come in contact with the lower rod members 151 and are ignited earlier than the upper rod members 152, 153, thus, burning duration of the lower rod members 151 must be extended by increasing bulk of the lower rod members 151, thereby extending burning duration thereof to cooperate in enabling easy burning of the uppermost rod members 153, thereby achieving regulation of synchronous terminal combustion.
The enclosing body 1 is fabricated by interlocking a plurality of rod members, and fine nails are used to nail together and fixedly assemble the interlocked configuration, as depicted in FIG. 5. Physical properties of the fine nails appropriate for use in fixedly assembling the enclosing body 1 of the present invention are as described above, and nailing method is not described herein.
Each of the rod members 151, 152, 153 or surrounding boards 221, 222, 23 of the bottom frame 20 can adapt and adopt material as per the description for FIG. 5.
Carbon fuel is disposed within the holding space 11, and the carbon fuel 4 can be formed as fuel of standardized specifications. Such standardized fuel can be formed by high-temperature pressing plant fiber or shreds, thereby forming standardized fuel such as tubular plant carbons 7. The tubular plant carbons 7 fuel having identical exterior specifications is arranged in rows within the holding space 11, and using such a row arrangement enables the formation of uniform flame paths during the course of combustion. Moreover, oxygen required for combustion is able to enter the lateral through holes 12.
The aforementioned plant carbons 7 have circular or other geometric cross sectional shapes, and thermal reaction on the surface of a circular shape is relatively uniform. Moreover, production of circular shaped plant carbons is easy, and arrangement of the plant carbons 7 having identical cross-sectional areas within the holding space 11 enables forming substantially large fume passages 70 (see FIG. 10).
The plant carbons 7 is formed by compressing pulverized plant fiber, using coconuts, palm, wood chips, and so on, as the primary material, major consideration being that exterior dimensions can be adapted to fit conditions.
The plant carbons 7 is processed to finalize the shape, and a channel 71 is defined in a center of each of the plant carbons 7 (see FIG. 10). After the fire grate 2 (see FIG. 9) has undergone combustion and deforms or is consumed, then a lower end opening of the enclosing body 1 correspondingly opens up an air passageway, and air enters bottom ends of the channels 71 and rises upward, thereby forming a chimney effect that increases ambient air convection speed, thus providing a sufficient oxygen supply. Of course, after the fire grate 2 collapses, the aforementioned plant carbons 7 also collapses. However, because the plant carbons 7 was originally disposed in erect positions, thus, it is extremely likely that the plant carbons 7 collapse at sloping angles and mutually crossover, thereby enabling the slanting plant carbons 7 to similarly form a chimney effect. Even in a horizontal straddling position, because ambient air pressure blows from a single side at a single angle, thus, airflow only enters a single end of each of the channels 71 and exits the other ends, thereby enabling the channels 71 to similarly provide a basis for air flow exchange. Moreover, when air flows into the ends of the channels 71, the ends will simultaneously meet with corresponding thermal heat brought in by the air, and heat exchange takes pace with walls of the channels 71, thereby achieving ignition points having a similar internal ignition effect.
The through holes 21 formed by the spaced intervals of the gird-type fire grate 2 can similarly function to enable a supplementary supply of oxygen to enter the structural configuration.
The conjoined structural configuration of the bottom frame 20 and the upper enclosing body 1 can use connecting rods 120 vertically disposed at corners of the enclosing body 1 and the bottom frame 20, thereby enabling the packing body 10 to form a combined integrated body configuration.
Referring to FIG. 9, after packing the plant carbons 7 in rows within the packing body 10, the kindling 3 is co-packed with the bottom frame 20 of the lower portion, whereafter another paper-like packaging bag can be used to enwrap the exterior, such as a paper bag, any plastic bag, and so on, thereby providing the enclosing body 10 with a secondary periphery packing, and co-packaging of the kindling 3 within the raised space H of the bottom frame 20. If an outermost layer packaging bag 110 is used to enwrap and seal the enclosing body 10, then the kindling 3 is located within the bottom frame 20 when transporting, or when selling or displaying. A user first opens the periphery packaging bag 110, whereupon he is able to take out the kindling 3 and carry out the ignition procedure. After the kindling 3 has ignited, then flames first burn the fire grate 2, and after the fire grate 2 has reached a self-combustion state, then self-combustion flames of the fire grate 2 cause a bottom portion of the plant carbons 7 to commence burning, thereby implementing the process for total ignition.
The method used to upwardly join the aforementioned bottom frame 20 to the packing body 10 can use different material to separate the two for different applications. For instance, the bottom frame 20 can use segmented pressure-fiber board material, and the enclosing body 1 of the upper portion can be fabricated by adopting the aforementioned structural configuration of rod members, or formed by folding paper, or, because exterior form of the plant carbons 7 is standardized, a binding wire method can be used to laterally bind and join them to the bottom frame 20. Because of the multitude of applications of the enclosing body 1, major consideration is that material used for the enclosing body 1 is combustible, and combustion of natural material that does not produce toxic gas is preferred. Moreover, co-joining with the bottom frame 20 must be achievable.
The channels 71 defined center of the plant carbons 7 were originally designed to provide surface areas for contact with oxygen. The packaging method of the present invention goes one step further by vertically positioning the channels 71 directly above the fire grate 2, thereby enabling cross sections of the fire grate 2 to obstruct the channels 71, as depicted in FIG. 10.
Object of which is to use the fire grate 2 to directly support the plant carbons 7, and because each of the plant carbons 7 are standardized as circular bodies, thus, opposite facing arc surfaces between the closely packed plant carbons 7 form the substantially large fume passages 70, which are used to accommodate flow of a large amount of fumes, whereas cross-section of the channels 71 is relatively small, and only enables a relatively poor convection speed. Hence, the aforementioned method using the fume passages 70 enables a substantially superior through flow of fumes, and facilitates initial ignition and easy air flow.
When the fire grate 2 is used to singly upwardly support a single row of the plant carbons 7, then bearing capacity is singly allocated. Furthermore, because the plant carbons 7 are of equally standardized circular specifications that are disposed within the holding space 11, thus, after the plant carbons 7 have been arranged within the holding space 11, then opposite corner spaces at ends of the enclosing body 1 enable positioning of the connecting rods 120 therein.
Hence, the plant carbons 7 are manufactured to have exterior form of equal specifications facilitates arranging them in rows, and internal width of the enclosing body 1 can be set to accord with a multitude of diameters of the plant carbons 7. Furthermore, the plant carbons 7 can be similarly designed to have square cross sections or other geometric cross sections. However, the circular shape is the preferred shape under normal conditions, because surface of the circular shape is even, thus, frictional velocity of fume flow along surfaces will be approximately the same, and tangential contact points between adjacent plant carbons 7 is linear, thereby enabling the formation of substantially large fume passages 70.
According to disposition of the aforementioned plant carbons 7, the channels 71 defined in longitudinal centers of the plant carbons 7 are able to form a thermal convection chimney effect when the channels 71 are positioned vertically, whereas, if angular disposition of the plant carbons 7 are adjusted to be horizontal and sequentially juxtaposed on top of the fire grate 2 in a front to rear tandem connection fashion (see FIG. 11), then the channels 71 can be regarded as having no function prior to the exterior of the plant carbons 7 cracking and deforming from firing, and initial combustion merely burns the tubular exterior of the horizontally disposed plant carbons 7 while interiors of the channels 71 are in an evasive, a thermal reaction state. However, when total combustion commences, because inner cylindrical surfaces of the channels 71 are not yet affected by heat, thus, they maintain a low temperature, and will not burn at the same time as the exterior of the plant carbons 7, moreover, time difference between burning of the exterior and interior of the plant carbons 7 can delay combustion rate of the entire structure, thereby facilitating barbecuing food material that does not need a high roasting temperature, such as high protein food material.
Accordingly, the aforementioned modulation method is able to reduce heat output within a unit time, and combustion rate is correspondingly reduced, thereby delaying combustion duration. Hence, lowering thermal power within a unit time enables achieving slow fire roasting, whereby the slow fire substantially lengthens heat transmission time for roasting the food material, thereby enabling heat on the exterior of the food material to penetrate to the center of the food material. Moreover, the exterior of the food material will not be overheated and become charred, thereby enabling substantially uniform heating of the interior and exterior of the food material close to synchronous thermalization.
The aforementioned plant carbons 7 can be formed by obtaining material from wood chip fiber, which is then molded using combined high temperature pressure. The fiber can also be obtained from plants, such as coconuts, palm, snake wood, and so on, which is first pulverized and then molded using high temperature pressure to form coconut carbon, and so on.
Combustion value and combustion duration of fuel material formed from wood chip fiber that has undergone high temperature pressure is the largest. Hence, if the carbon fuel 4 is to be used for an extended period of time in a barbecue, then carbon fuel formed from wood chip fiber that has undergone high temperature pressure is preferred.
The embodiment of the bottom frame 20 of the present invention (see FIG. 5) primarily comprises a configuration wherein the upper portion forms the combustible fire grate 2, and the bottom portion forms the raised space H that enables the kindling 3 to be disposed therein, thereby forming a two stage combustion operation. If strong lateral wind flow is not a consideration, then any support members, such as stilts, a baseboard, blocks of wood or stone, and so on, may be used to support the grid-type fire grate 2, thereby enabling the lower portion to form the raised space H for disposing the kindling 3 therein. Such configurations used in the formation of the raised space H are included in the embodiments of the present invention.
The carbon fuel 4 loaded on the fire grate 2 of the present invention (see FIG. 9) Is basically laid out in a one layer column arrangement or more than two stacked layers, and height of the enclosing body 1 can be adapted according to height of the layers. For one layer of normalized fuel such as the plant carbons 7, then the plant carbons 7 can be arranged in an upright or horizontal configuration, and decision whether to use a horizontal or vertical configuration is based on length of combustion period requirements, wherein orientation of the channels 71 in a horizontal or vertical arrangement affects degree of oxidation.
Referring to FIG. 12, wherein a packing body is configured with the bottom frame 20, and the grid-type fire grate 2 supports the carbon fuel 4 or plant carbons 7. Alignment method used to arrange the carbon fuel 4 or plant carbons 7 is identical to that described above. An upper end of the enclosing body 1 is extended to form an upper layer enclosing body 1A by means of extending portions 200, and a bottom portion of the upper layer enclosing body 1A is separated using an upper layer grid-type fire grate 2A. The upper layer grid-type fire grate 2A similarly provides for loading of the carbon fuel 4 or the plant carbons 7 on top thereof. The kindling 3 is then entered through intake holes 201 defined in the extending portions 200, and, according to operating ignition path, the kindling 3 does not need to be placed in the bottom frame 20. After entering the kindling 3 through the intake holes 201 and ignited, heat waves are similarly transmitted upwards to ignite the upper layer grid-type fire grate 2A, and intervention of the upper layer grid-type fire grate 2A causes relatively large flames to be generated that initialize extensive kindling and comprehensive burning of the upper layer fuel.
Heat waves from the burning kindling 3 is universal radiation, and apart from air current heat effect causing upward transmission, the heat waves can also be similarly transmitted downward and ignite outer surfaces of the lower layer carbon fuel or plant carbons 7. According to the physics of thermal currents, it is known that the carbon fuel or plant carbons 7 of the upper layer will first undergo extensive burning, thereby effecting advanced combustion of the upper layer fuel, and brittle remaining pieces will then drop down and fall onto outer surfaces of the lower layer carbon fuel 4 or plant carbons 7, thereby similarly igniting and initializing burning of the carbon fuel 4 or plant carbons 7. However, because only the outer surfaces of the lower layer carbon fuel 4 or plant carbons 7 catch fire, hence, the entire combustion speed is substantially slowed down.
All auxiliary air needed for combustion enters through the bottom frame 20 or the intake holes 201.
The raised space H is able to satisfy disposition of the kindling 3 and operating ignition.
The aforementioned kindling 3 similarly can be wood fiber mixed with mineral oil and wrapped using oiled paper as described above, or can be fabricated from solid alcohol sealed within flammable packaging.
In order to obtain vigorous thermal power, apart from disposing the kindling 3 in the raised space H of the extending portions 200 to enable combustion initiation of the girth portion, the kindling 3 can also be synchronously disposed within the raised space H of the bottom frame 20 and simultaneously ignited to cause synchronous burning of the upper and lower layer carbon fuel 4 or plant carbons 7. Furthermore, implementing a synchronous burning operation effects rapid ignition, and after combustion within a unit time, a relatively large heat output is generated, thereby achieving vigorous burning, and ashes are similarly formed after complete combustion of the material of the enclosing body. The enclosing body is similarly fabricated from a plurality of wooden bars, which apart from being made of natural wood material, can also be formed by cutting pressed boards fabricated from wood fiber. The plant carbons 7 of identical form and specifications can be arranged according to the aforementioned alignment method within the holding space 11. During the course of combustion, the plant carbons 7 undergo extensive burning identical to the principle depicted in FIG. 5 and FIG. 9, and alignment method used to arrange the plant carbons 7 is identical to the systematic arrangement concept depicted of FIG. 10.
It is of course to be understood that the embodiments described herein are merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
