Boilers are often used in thermal power plants or other industrial and civil production.

The boiler is composed of two parts: pot and stove. A pot is a container for water. Stoves are places where wood is burned. The hot smoke generated by the combustion of wood in the stove uses heat transfer, convection and radiation to transfer the heat of the hot smoke to the water in the pot to generate steam.

However, the flow rate of outside air into the stove is very fixed and cannot be adjusted. Therefore, the conventional boiler can only provide the firewood to burn at the maximum air flow rate to generate the maximum firepower, and the firepower cannot be adjusted.

Furthermore, the conventional boiler has a poor structural design and is not easy to ignite the firewood, and it cannot completely transfer all the heat of the hot smoke generated by the combustion in the stove to the water in the pot. Therefore, conventional boilers usually require a considerable amount of firewood to obtain high-temperature water and steam, and the heating time is long.

In addition, the conventional boiler is not equipped with any safety devices. Once the steam temperature exceeds 115 degrees and the steam pressure is greater than the external atmospheric pressure, the boiler will explode, which is quite dangerous.

The following will illustrate the use of the present invention and the effects it can achieve with the drawings.

As shown in FIG. 9, first, before being used, the first door panel 231, the second door panel 232, and the third door panel 233 are all located in a closed position. Therefore, the first door panel 231 completely closes the open end 2121 of the feed pipe 212, and an inner side of the second door panel 232 abuts against an outer side of the third door panel 233, so that the second door panel 232 and the third door panel 233 are both completely closed. The open end 2131 of the intake pipe 213. At this time, there is no liquid in the chamber 111, and no firewood 100 is placed on the deflector 25.

As shown in Figure 10, an inlet end of the water inlet pipe 15 is used to connect a delivery pipe 101, the delivery pipe 101 is connected to a cold water bucket (not shown), and a first on-off valve 102 is provided on the delivery pipe 101; A water outlet end of the water pipe 16 is used to connect a first drain pipe 103, the first drain pipe 103 is connected to a hot water appliance (not shown), and a second switch valve 104 is provided on the first drain pipe 103.

After the first switch valve 102 is opened, the cold water provided by the cold water bucket passes through the delivery pipe 101 and the water inlet pipe 15 in sequence, and then flows out from the water outlet end of the water inlet pipe 15 and flows down to the top surface of the tray 24 by gravity . The cold water flows along the top surface of the inclined plate body 24 to the inner peripheral side of the plate body 24. After passing through the notches 241 on the inner peripheral side of the tray 24, the cold water flows along the outside of the chimney 22 toward the base 13. It should be noted that the water level in the chamber 111 must be maintained below the plate body 24, so as to allow a certain space above the chamber 111 to accommodate steam.

As shown in FIG. 11, the first door panel 231, the second door panel 232, and the third door panel 233 are located in an open position, so that the first door panel 231 fully opens the open end 2121 of the feed pipe 212, the second door panel 232 and the third door panel 233 Together, the open end 2131 of the intake pipe 213 is fully opened. The user can throw the firewood 100 from the open end 2121 of the feed pipe 212, and the firewood 100 slides along the feed pipe 212 by gravity into the combustion space 2111 and is stuck on the deflector 25. The user can place some kind of fire 105 on the top surface of the base 13 along the intake pipe 213 and ignite the fire 105 so that the fire of the fire 105 further ignites the wood fire 100.

Since the first door plate 231 fully opens the open end 2121 of the feed pipe 212, and the second door plate 232 and the third door plate 233 together fully open the open end 2131 of the intake pipe 213, the outside air enters through the feed pipe 212 at the maximum flow rate. The combustion space 2111 and the outside air enter the combustion space 2111 through the intake pipe 213, the intake space 2112, and the guide holes 253 in sequence at the maximum flow rate. Therefore, the maximum flow of oxygen in the combustion space 2111 can be used for the combustion of the firewood 100, which makes the firewood 100 burn fiercely and generates hot smoke with extremely high temperature.

As shown in Figure 11, because the firewood 100 and sufficient oxygen complete the combustion reaction, all the combustible substances contained in the firewood 100 can release all the heat of the firewood 100 after being combined with oxidation, so that the firewood 100 can be fully utilized. And can produce clean hot smoke. The heat released by the firewood 100 when it burns and the heat of the hot smoke can be transmitted to the cold water in the chamber 111 through the side wall of the combustion tube 211, the outer wall of the spiral part 221 and the outer wall of the straight cylinder part 222, so that the temperature of the cold water gradually rises to boiling. And it produces steam. After the steam rises through the steam hole 121, it is discharged outward. As the hot smoke rises through the spiral portion 221 of the chimney 22, a cyclone is formed along the spiral inner wall surface of the spiral portion 221. After the cyclone-like hot smoke rises through the straight cylindrical portion 222, it is discharged outward.

The user can additionally install a steam duct (not shown) on the steam hole 121, and the steam duct guides the steam to a stove (not shown). In this way, the user can use steam to cook food on the stove.

When the present invention is installed indoors (for example, a barn), the hot smoke can be used as heating to fill the entire indoor space, causing the temperature of the indoor space to rise, so that the present invention becomes a heating device.

As shown in FIG. 10, after the second on-off valve 104 is opened, the hot water passes through the first drain pipe 103 to the hot water facility. The hot water device can be a faucet that provides hot water in a bathroom, a device for extracting essential oils, or a device for boiling milk. However, the above-mentioned several types of hot water equipment are for illustrative purposes only, and are not limited thereto.

What is important is that when the first door panel 231 stays at any position between the open position and the closed position, the first door panel 231 gets closer to the open end 2121 of the feed pipe 212, and the outside air enters the combustion space 2111 through the feed pipe 212. Conversely, the farther the first door plate 231 is from the open end 2121 of the feed pipe 212, the greater the flow of external air into the combustion space 2111 through the feed pipe 212. When the second door panel 232 is in the closed position and the third door panel 233 stays at any position between the open position and the closed position, an outer side surface of the second door panel 232 and an inner side surface of the third door panel 233 form a gap 237 (See FIG. 12), the gap 237 communicates with the intake pipe 213. The closer the third door plate 233 is to the open end 2131 of the intake pipe 213, the smaller the size of the gap 237, and the more external air flows into the combustion space 2111 through the intake pipe 213, the intake space 2112, and the guide holes 253. On the contrary, the third door plate 233 is farther away from the open end 2131 of the intake pipe 213, the size of the gap 237 is larger, and the outside air enters the combustion space through the intake pipe 213, the intake space 2112 and the guide holes 253 in sequence The 2111 traffic is greater. Among them, the greater the air flow into the combustion space 2111, the more intense the firewood 100 burns, the greater the firepower, and the faster the heating speed; relatively, the smaller the air flow into the combustion space 2111, the weaker the firewood 100 burns, and the lower the firepower. , The heating speed is slow.

As shown in FIG. 12, the first door panel 231 is in the closed position, so that the first door panel 231 completely closes the open end 2121 of the feed pipe 212. Therefore, the user cannot throw the firewood 100 into the combustion space 2111 from the feed pipe 212, and at the same time, the outside air cannot enter the feed pipe 212. The second door panel 232 is in the closed position. The third door panel 233 stays somewhere between the open position and the closed position. The outer side of the second door panel 232 is quite close to the inner side of the third door panel 233, but the outer side of the second door panel 232 and the inner side of the third door panel 233 The sides are not pressed together. At this time, the gap 237 between the outer side surface of the second door panel 232 and the inner side surface of the third door panel 233 is maintained at a minimum size, and the outside air passes through the intake pipe 213, the intake space 2112, and the guides in sequence with the minimum flow. The hole 253 enters the combustion space 2111, the firewood 100 burns the least, and the firepower is the least, and the water temperature can be maintained.

As shown in FIG. 11, the ashes 106 produced by burning the firewood 100 are of heavier mass, so the ashes 106 can pass downward through the guide holes 253 by gravity and fall onto the top surface of the base 13. Because the top surface of the base 13 is an arc-shaped convex surface, the ashes 106 can slide down along the top surface of the base 13 toward the opening end 2131 of the intake pipe 213 by gravity. The user only needs to open the second door panel 232 and the third door panel 233 to remove the ashes 106 in the air intake space 2112.

As shown in Figure 14, when the steam pressure in the chamber 111 is greater than the outside atmospheric pressure, especially when the steam temperature is higher than 115°C, at this time, because the cross-sectional area of the steam hole 121 is small, the steam that can be discharged is limited and cannot be timely. The pressure is relieved, so that the safety valve 192 is pushed by the steam pressure to escape from the open end of the pressure relief pipe 191 located outside the chamber 111. After the safety valve 192 is separated from the open end of the pressure relief pipe 191 located outside the chamber 111, the steam in the chamber 111 can be discharged from the pressure relief pipe 191, thereby reducing the steam pressure in the chamber 111 and avoiding the explosion of the present invention .

As shown in FIGS. 4 to 6, 9 and 10, in the first embodiment, the stove 20 further includes a plurality of heat conducting plates 26. The heat conducting plates 26 are arranged around an outer side surface of the side wall of the combustion cylinder 211 and are arranged longitudinally. More clearly, each heat conducting plate 26 is made of a material with good heat conduction effect, and therefore has a good heat conduction effect; each heat conducting plate 26 has a horizontal plate 261, a first side plate 262 and a second side plate 263. The horizontal plate 261 is provided on the side of the combustion cylinder 211 relative to the feed pipe 212 and the intake pipe 213 and is inclined upward. The first side plate 262 and the second side plate 263 are respectively provided on the other two sides of the combustion cylinder 211. One end of the first side plate 262 and one end of the second side plate 263 are respectively connected to the two ends of the horizontal plate 261. The first side plate 262 and the second side plate 263 The side plates 263 are inclined downward from the two ends of the horizontal plate 261 respectively. In other words, the structure of each heat conducting plate 26 is U-shaped and inclined. Thereby, part of the heat released when the firewood 100 is burned and part of the heat of the hot smoke can be further transferred to the heat conducting plates 26 through the side wall of the combustion cylinder 211, and the heat conducting plates 26 transfer the heat to the cold water in the chamber 111. , Improve the effect of heating cold water.

To sum up, the present invention achieves the effect of multi-stage adjustment of firepower by multi-stage adjustment of the flow of external air into the combustion space 2111 through the feed pipe 212 and the intake pipe 213, thereby controlling the heating rate of the cold water.

Furthermore, the structure of the present invention is properly designed, so the firewood 100 is easy to ignite, and the firewood 100 can be fully burned, and the heat released when the firewood 100 is burned and the heat of hot smoke are all transferred to the chamber 111 through the side wall of the combustion tube 211 The cold water, so it has the advantages of less consumption of firewood 100 and short heating time.

Please refer to FIGS. 15 and 16, which are respectively a perspective view and an exploded view of a steam hot water boiler according to a second embodiment of the present invention. In the second embodiment, the chimney 22 further includes a dust collecting part 223, and the dust collecting part 223 has a curved section 2231 and a vertical section 2232. The curved section 2231 has a first end and a second end. The first end of the curved section 2231 is disposed on the top of the straight cylindrical section 222, and the curved section 2231 is bent downward. The vertical section 2232 is provided on one side of the curved section 2231 and communicates with the second end of the curved section 2231. An exhaust port 22321 is provided at the top of the vertical section 2232, and a dust collecting port 22322 is provided at the bottom of the vertical section 2232.

Generally speaking, in the initial stage of the combustion of the firewood 100, the combustion reaction with oxygen has not yet been completed, and the hot smoke generated at this time contains dust and hot air. Because the mass of dust is small, it is easy to be mixed in the hot air as the hot air flows. As shown in Fig. 16, the tornado-like hot smoke enters the curved section 2231 of the dust collecting section 223 after passing through the straight cylinder 222, and then passes through a bend from the first end of the curved section 2231 and then downwards to the curved section 2231 Flow in the direction of the second end. The hot smoke enters the vertical section 2232 after passing through the second end of the curved section 2231. After the hot smoke enters the vertical section 2232, the dust in the hot smoke moves downward along the vertical section 2232 by gravity, and the hot air in the hot smoke flows upward along the vertical section 2232. After passing through the dust collecting opening 22322, the dust moving downward by gravity leaves the dust collecting part 223 and falls down to the ground or a dust collecting device (for example, a dust bag, not shown). After the hot air flowing upward passes through the exhaust port 22321, it leaves the dust collecting part 223 and flows upward to the outside space. In other words, the dust collecting part 223 can further separate the dust in the hot smoke from the hot air, so that most of the dust falls down to the ground or collected in the dust collection device, so the hot air is very clean with almost no dust. , Reduce air pollution and provide cleaner heating.
