Description

Coal briquettes {formed charcoal}

The present invention relates to solid fuels and more particularly to coal briquettes.

Charcoal is a type of solid fuel used in cooking and heating in everyday life. In particular, oak and oak trees such as oyster oak and oak wood cut to the appropriate size to put in the kiln baked at high temperature is called charcoal. After refining the wood in the charcoal at 400 ~ 700 ℃, the oxygen is cut off in the kiln and put out for 2 ~ 3 days, and it is called black charcoal. It is called white charcoal to take out the fire at a high rate by taking out a mixture of soil, ash, and coal fire.

In general, the charcoal used as fuel is known to be the best charcoal, but the oak charcoal has a disadvantage in that the raw material supply is very limited and expensive so low profitability. In addition, although charcoal may be used in the form made, it is usually bulky, so it is not easy to handle, and it costs a lot of distribution, so it is often made coal briquettes. Coal briquettes may be made by shaping charcoal into finely divided charcoal to make a commercial product, or by first shaping and shaping the wood into charcoal.

In addition, in order to suit the function required for the components of the charcoal itself, or to reduce the price, in many cases, the coal briquettes are made by blending other components. Currently, many restaurants use charcoal charcoal in which charcoal itself occupies most of the ingredients. For outdoor use, charcoal charcoal mixed with moisture, a binder and a complexing agent is used.

Dry grenade is manufactured by injection molding the raw material into an injection molding machine and carbonizing it even when waste wood is used. Since it is dried beforehand, volatiles and caking agents are removed and no smell or smoke is produced. There is a drawback of cost. The complexed coal has an advantage of easily ignited because it contains a complexing agent therein, but has the disadvantage of generating odors and smoke due to combustion of moisture and a binder.

On the other hand, in relation to the commercially available form, the complex coal is mainly made of a thin briquette form as shown in Figure 1 was used a lot of fire briquettes. As mentioned earlier, these ignition coals are advantageous for ignition but have a lot of smell and smoke, and have a problem that they are used for instant roasting because they are kept for a short time such as 25 minutes.

Grenade is mainly made in the form of a lump or a hole as shown in Figure 3, as shown in Figure 2, mainly made of charcoal powder, less smell and smoke, and once fired, the firepower lasts a long time, but it takes time to ignite It was hard to do.

Therefore, conventionally, the ignition coal was fired from the outside as shown in Fig. 1, and the coal grenade shown in Figs. Accordingly, in the existing instant roasting house, there is a trouble in terms of inconvenience and cost, such as setting up a manpower for making a fire while using coal briquettes as shown in FIG. 2 and FIG. 3.

The present invention is to improve the inconvenience of using the conventional coal briquettes described above, and an object of the present invention is to provide coal briquettes that can easily ignite and have a long-lasting fire and reduce odor and smoke during combustion.

An object of the present invention is to provide coal briquettes that can be burned evenly to increase the efficiency of combustion.

Coal briquettes of the present invention for achieving the above object,

It has a main body part and an ignition part distinguished from this main body part, The air hole is formed, It is characterized by the curvature of a lower surface.

In the present invention, the ignition part is located below the main body, and in particular, the ignition part may be formed in a conformally stacked form below the main body.

In the present invention, at least a main body portion is formed with an air hole penetrating the main body portion, and preferably, a consistent air hole is formed throughout the ignition portion and the main body portion. At this time, the air hole should have a section in the vertical direction at least in part, preferably the whole is formed in the vertical direction.

In the present invention, it is preferable that at least a part of the bottom curve is connected to the side surface so that air is supplied to a substantial portion of the bottom surface along the curve. For example, the curved surface of the lower surface may be formed in a long groove shape so that the lower surface passes in the left and right directions or the front and rear directions, and the grooves in the left and right directions and the grooves in the front and rear directions cross each other to form a checkerboard or mesh type. have. Or in the present invention, the bending may be made by a method of forming an embo (protrusion: embo) on the lower surface. The convex lower end portion of the lower surface of the main body portion may be made to be at a level lower than the lower end of the ignition portion of the concave portion (the recessed portion) below the main body portion. In addition, at least a portion of the air hole may be formed so that the inlet is in the concave portion of the lower surface.

In the present invention, the main body portion is made of charcoal, and the ignition portion may be made of ignition coal including a complex material.

The coal briquettes of the present invention for achieving the above object can be easily ignited and have a long-lasting fire, and have an effect of reducing odor and smoke during combustion.

The coal briquettes of the present invention have the effect of making combustion as a whole to increase the efficiency of combustion.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

4 and 5, as an embodiment of the coal briquettes of the present invention, a rectangular coal briquette having a rectangular box or rectangular plate shape is disclosed.

The square coal briquettes have an upper body portion 110 that occupies a large portion of the thickness and an ignition portion 120 positioned below the body portion 110. The upper surface of the main body 110 has a flat shape, and the air holes 130 and 140 penetrated in the vertical direction, forming a 3 × 3 matrix, are formed. On the lower surface of the main body 110, two grooves in the left and right directions are formed in parallel, and two grooves in the front and rear directions are formed in parallel with each other.

Grooves are formed to the same depth as other groove portions at the point where the left and right grooves and the front and rear grooves cross each other. The ignition unit 120 is conformally stacked along the curvature of the lower surface of the main body 110 so that the lower surface of the ignition unit 120, that is, the lower surface of the square shaped coal of the present embodiment, is the same as the lower surface of the main body 110. Has a checkerboard-shaped bend

If the concave portion in the lower surface bent concave portion 150, the convex portion may be referred to as the concave portion (160). Among the air holes, the inlet is formed in the lower surface of the recess 150, the recess air hole 130, and the inlet is formed in the lower surface of the concave portion 160 may be distinguished from each other. One long groove is formed from the peripheral end to the other end so as to divide the entire lower surface into two parts, so that when viewed from the side of the rectangular box-shaped coal briquettes, the groove 150 'is formed at the lower side of the square. A peripheral portion other than ') forms a protrusion 160'.

Thus, even if the coal briquettes of the present invention are placed on a flat brazier or other floor, and there is no separate hole in the bottom of the brazier, the groove 150 'may be referred to as a part of the bottom surface, and connected to the bottom surface. Through the outside air can be supplied to the entire lower surface, and through the recessed air hole 130 is connected to the lower surface to enable to supply the external air to a significant portion of the coal briquettes.

Looking at the method of fire in this embodiment, first, using the ignition means such as a lighter or a match to ignite the lower ignition portion 120 of the coal briquettes of this embodiment. The ignition unit 120 may be formed by forming a paste into a charcoal pulverized product obtained from miscellaneous wood parts in a form of a paste by putting a complexing agent, a binder for molding, and the like into a paste, so that the ignition unit 120 may be laminated on the lower surface of the main body unit 110 without any other kind of fire plug. It is easy to ignite, even if only a part of the ignition due to the characteristics of the ignition unit 120, the fire easily spreads to the entire ignition unit 120, through which the coal briquettes are expanded to the whole.

The layer constituting the ignition unit 120 burns and ignites the main body unit 110, the upper portion of which is the heat released therefrom. The ignition unit 120 is composed of a thin layer necessary for ignition of the main body 110, which is the upper portion, and the material is usually formed of a material that is easier to burn than the main body 110, so it is burned within a short time, and thus the ignition unit 120 burns. Smoke and odors will soon disappear. The fire that is first ignited in the lower part of the main body 110 increases the thermal power while receiving oxygen supply by using the air flow through the air holes 130 and 140 formed in the main body 110, and the air holes 130 and 140 are caused by the flame generated at this time. Combustion is made to the entire body 110 around.

The coal briquettes of this embodiment have a groove, that is, a bottom recess 150 formed in the lower surface of the coal briquettes to facilitate the inflow of external air, and a plurality of air holes 130 are connected to the recess 150 when the lower inlet is formed. . Therefore, the outside air passes through the groove and the air hole 130 inlet to the air hole 130 outlet of the upper side of the coal briquettes, sufficiently supplies oxygen in the air, and also serves to heat the surroundings through hot air. The role of these air holes is to act as air holes in the briquettes, fire holes and chimneys of the oven. Therefore, even if the bottom of the furnace is flat, the air can flow well by its own shape, and the combustion can be carried out while maintaining the sufficient thermal power.

As a result of rough experiments with and without air holes, the air ignition time is about one-third, although there are some differences depending on the number of air holes and the frequency of installation. The effect was shortened to within 5 minutes. That is, a comparative example in which the existing ignition coal material is used in the ignition part and the coal briquettes using the coal briquettes as shown in Figs. Ignition experiments were carried out through examples. In this case, the embodiment with the air holes showed a result of reducing the time taken for stable ignition of the main body part to within 5 minutes, which is 1/3, compared with the case of the comparative example.

According to the results of this experiment, the thickness of the ignition part can be made to be about 1/3 of the thickness of the comparative example, and accordingly, it can have the effect of reducing the cost, the smell during ignition, and the smoke.

Meanwhile, after the ignition unit 120 is burned according to the material, the residue may have little mechanical strength. In this case, the ignition unit 120 after combustion, the ignition unit 120 is dissipated, may be left almost. Even in this case, the coal briquettes of the embodiment maintain the curved shape of the lower surface of the main body 110 so that air can be distributed without any problem.

On the other hand, in order to secure the air flow path in the present embodiment, the end of the lower surface convex portion 160, which is a protruding portion of the lower surface of the main body portion 110, that is, the ignition portion 120 laminated on the lower surface recessed portion 150 It is better to be at a lower level than the bottom of. In this case, when the ignition unit 120 is first burned and is not evenly dissipated and receives mechanical pressure, the convex portion 160 is first lumped away from the convex portion 160, and when the concave portion 150 remains, the original curvature formed on the lower surface is Can be nearly flat. In this case, if the main body 110 has an end of the convex portion 160, the lower portion of the concave portion 120 of the concave portion 150 is formed when the lower portion of the convex portion 160 of the convex portion 160 is formed. If all disappear, the ignition portion 120 of the recess 150, even if all remaining can still secure the flow path of air.

6 and 7, the circular coal briquettes of the present invention is similar in shape to the conventional coal briquette ignited ignition coal, but its configuration and operation principle are almost the same as those of the rectangular coal briquettes of FIGS. 4 and 5 described above. However, in this embodiment, a considerable number of air holes 240 are not connected to the grooves on the bottom of the coal briquettes (lower surface portion 250), thereby increasing the likelihood of continuously burning for a longer time while adjusting the fire power. The circular shape of the coal briquettes is more efficient for heating a heating mechanism having a circular cross section compared with the previous quadrilateral plane. For example, it is efficient to use circular coal briquettes in the present invention if the fire plate of the instant roasting house is circular, and to use square coal briquettes if the fire plate is rectangular.

8 and 9 show a quadrangular coal briquettes as another embodiment of the present invention. In this embodiment, the other contents are the same as those of the four-piece coal briquettes of FIGS. 4 and 5, but instead of stacking the ignition part 320 in a conformal form with the lower surface of the main body 310, the lower surface recess 350 Are concentrated on Even in this embodiment, the air hole 330 is formed to overlap the recessed portion 350 when the inlet is formed, and the ignition part 320 is also connected to each other, so that it is sufficient to transfer the fire to the entire coal briquettes upon ignition. .

In this embodiment, since the stacking area of the ignition unit 350 may be reduced, air pollution, smell, and smoke may be reduced. Therefore, in this embodiment, the ignition unit 350 is well ignited, and the thermal power is strong, but the smell, smoke, and toxic substances are less emitted (particularly, the characteristics of such a good but expensive material means saving material costs. If it is formed in the furnace) will have the advantage of being able to use the fire in the room.

10 and 11 show a quadrangular coal briquettes as another embodiment of the present invention. In this embodiment, the difference is the same as that of the quadrangular coal briquettes of FIGS. 4 and 5, but in forming a lower surface, the main body 410 has a feature of forming an embossed shape protruding downward only in part. In this embodiment, the ignition unit 420 may be formed on the entire lower surface or only the remaining portions except the lower surface convex portion 460 in the form of an emboss. In this form, there is an advantage that free flow and inflow of air below the coal briquettes can be easily introduced into all air holes from the beginning, thereby increasing the ignition speed and fire power of the coal briquettes.

The present invention has been described above through some embodiments, but the present invention is not limited to these embodiments.

  In the present invention, in common, the ignition unit and the main body unit may be considered to use a conventional ignition coal material and a grenade material. However, the coal briquettes according to the embodiment of the present invention can maintain a faster ignition speed, higher temperature and fire power than the coal briquettes by the ignition portion, the air hole, and the lower surface of the coal briquettes. It is also conceivable to form a mixture of strong and inexpensive anthracite coal. In the case of the ignition part, a relatively inexpensive charcoal bark (the charcoal part of the tree is almost discarded or sold at a low price. The ignition is less than that of carbon, which contains a large amount of impurities other than carbon). It is easy to use, and it is possible to use a mixture of materials such as sawdust and the like that is rarely generated in the production of white coal. The components of the other ignition and body parts are commonly known in the art in connection with ignition coal and charcoal, and the discussion of specific components is omitted since many conventional modifications are possible in the specific material.

In addition, since the duration may be controlled by the number or arrangement of air holes or the thickness of the main body, various modifications of the present invention, in which the total calories, the duration, and the controllability are designed in various ways, may be used.

Another thing to mention is that each of the examples of coal briquettes has been described in the above embodiments, and mainly the use of one coal briquettes is described. In other words, when a large amount of thermal power is required at the same time or when the coal briquettes are made small, a plurality of coal briquettes can be arranged in a plane or stacked in multiple layers.

When stacked and used in multiple layers, the coal briquettes as in the above embodiments are conveniently stacked and used in a regular form, and both of the coal briquettes of the present invention have bends formed on the lower surface of the coal briquettes according to the present invention. Even if the air holes of the coal briquettes are not aligned between the layers, such bends can easily be introduced between the stacked layers and the layers of the coal briquettes, and the air is uniformly supplied from the stacked coal briquettes and a good fire power can be maintained.
