[0034] Combination Figure 1-5 As shown, this embodiment of the present disclosure provides a gasification furnace, including: a furnace body 100, which is a circular barrel-shaped structure with an open top; a gasification liner 200, which is also a barrel-shaped structure with an open top, the gasification liner 200 being disposed inside the bottom side of the furnace body 100, the bottom of the gasification liner 200 being provided with furnace bars 201, and the upper side of the gasification liner 200 being provided with an air inlet 202; a connecting plate 203, which is sleeved on the upper opening of the gasification liner 200, and the outside of the connecting plate 203 is connected to the inner side wall of the furnace body 100; and an air damper 300, which is disposed on the lower side of the furnace body 100.
[0035] The gasifier provided in this embodiment has a furnace body 100 that is a circular barrel-shaped structure with an open top. The gasification liner 200 is also a barrel-shaped structure with an open top. The bottom of the gasification liner 200 is provided with grate bars 201, and the upper side is provided with air inlets 202. Air can be supplied into the gasification liner 200 through the grate bars 201, and secondary air supply can be provided through the air inlets 202, increasing the combustion efficiency of the fuel in the gasification liner 200. The outer diameter of the gasification liner 200 is smaller than the inner diameter of the furnace body 100. The furnace body 100 is fitted over the gasification liner 200. A connecting plate 203 is fitted over the upper part of the gasification liner 200. The inner side of the connecting plate 203 is connected to the opening of the gasification liner 200, and the outer side of the connecting plate 203 is connected to the inner wall of the furnace body 100. Thus, the connecting plate 203 divides the furnace body 100 into upper and lower sections. The furnace body 100 consists of a lower chamber and a gasification liner 200. An air damper 300 is located at the bottom of the furnace body 100 to supply air to the gasification liner 200 within the lower chamber. The gasification liner 200 can hold fuels such as firewood, biomass pellets, or coal for combustion. Air is initially supplied to the gasification liner 200 via the bottom grate bars 201, allowing for combustion of the fuel. A secondary air intake 202 at the top of the gasification liner 200 provides oxygen to the fuel, increasing combustion efficiency and reducing smoke production. The upper chamber of the gasification liner 200 also holds firewood and other fuels, serving as a container for bonfires. Combustion within the gasification liner 200 ensures more complete and stable combustion of the firewood.
[0036] Optionally, the upper part of the vaporization liner 200 is a frustum-shaped tubular structure, and the air inlet 202 is disposed on the side wall of the frustum-shaped tubular structure.
[0037] In this way, the upper part of the gasification liner 200 is a frustum-shaped tubular structure, which is more conducive to the air inlet 202 being directed toward the gasification liner 200. This allows the air entering through the air inlet 202 to be directly blown toward the fuel surface inside the gasification liner 200, thereby improving the gasification and combustion efficiency of the fuel.
[0038] Optionally, an oxygen-enriching hole 101 is provided on the side wall of the furnace body 100 above the connecting plate 203.
[0039] In this way, the oxygen-enriching holes 101 on the side wall of the furnace body 100 allow outside air to enter the upper cavity of the furnace body 100 and mix with the flame and flue gas discharged from the gasification liner 200, thereby further improving the complete combustion of the flue gas and combustibles in the flame and achieving more environmentally friendly emissions. This design not only improves combustion efficiency but also helps save fuel and extend combustion time.
[0040] Optionally, an adjusting ring 102 is provided on the inner side of the oxygen-enriching hole 101. The outer wall of the adjusting ring 102 is in close contact with the inner wall of the furnace body 100, and an adjusting air hole 103 is provided on the side wall of the adjusting ring 102. The adjusting ring 102 is rotatably disposed on the inner wall of the furnace body 100.
[0041] In this way, the adjusting ring 102 can be plugged onto the oxygen supply hole 101. The adjusting ring 102 has an adjusting air hole 103 that matches the oxygen supply hole 101. By rotating the adjusting ring 102, the overlap between the oxygen supply hole 101 and the adjusting air hole 103 can be controlled, thereby adjusting the amount of air entering the furnace body 100. This allows for precise control of the combustion temperature and flame size, ensuring that the fire is both stable and efficient. By controlling the opening and closing degree of the oxygen supply hole 101, the air supply of the oxygen supply hole 101 can be finely controlled. Through this adjustment mechanism, users can flexibly adjust the air intake according to actual combustion needs to achieve the best combustion effect. While ensuring efficient combustion, it can also effectively control the fire size, making the device suitable for outdoor campfires.
[0042] Optionally, the furnace body 100 has an adjustment port 104 on its side wall, the outer wall of the adjustment ring 102 covers the adjustment port 104, and the outer wall of the adjustment ring 102 is provided with an adjustment rod 105, which extends out of the adjustment port 104.
[0043] In this way, the adjustment port 104 on the side wall of the furnace body 100 can connect the adjustment ring 102 to the outside of the furnace body 100. The adjustment rod 105 on the adjustment ring 102 allows the user to operate the adjustment ring 102 from the outside of the furnace body 100 to achieve fine adjustment of the air intake. The adjustment ring 102 completely covers the adjustment port 104, which can seal the adjustment port 104 to ensure the airtightness of the furnace body 100 and prevent air from entering the furnace body 100 through the adjustment port 104, thereby affecting the combustion efficiency.
[0044] Optionally, a flue hood 204 is provided on the upper part of the gasification liner 200, and a flue pipe 205 is provided on the upper part of the flue hood 204, with the upper part of the flue pipe 205 extending out of the upper part of the furnace body 100.
[0045] In this way, the smoke hood 204 on the vaporization liner 200 covers the vaporization liner 200, which can guide the flame and smoke inside the vaporization liner 200 into the smoke pipe 205, and then the smoke pipe 205 guides the smoke out of the oven body 100, preventing the smoke and flame from entering the upper cavity of the oven body 100. This allows the upper cavity of the oven body 100 to achieve smokeless and flameless heating, which is convenient for baking foods that need to be kept away from smoke and flame. Furthermore, the smoke hood 204 and the smoke pipe 205 are placed on the vaporization liner 200, making them easy to replace and disassemble.
[0046] Optionally, the upper part of the furnace body 100 is covered with a placement ring 106. The placement ring 106 is a circular ring structure with a hole in the middle. A plurality of placement grooves 107 are arranged around the inner side of the placement ring 106. Metal tags 108 can be inserted into the placement grooves 107.
[0047] Thus, the upper part of the oven body 100 is covered with a placement ring 106, which is a disc with a hole in the middle. Multiple placement slots 107 are provided on the inner side of the disc. The placement slots 107 are arranged in parallel around the inside of the placement ring 106 in a circular arrangement. The placement slots 107 can accommodate metal skewers 108. The metal skewers 108 are provided with handles on the upper part. The placement slots 107 are grooves that extend outward from the inner side of the placement ring 106. The metal skewers 108 are inserted into the placement slots 107. The handles on the upper part of the metal skewers 108 are provided on the upper part of the placement slots 107, which makes it easy to fix the metal skewers 108 on the upper part of the placement slots 107, so that the metal skewers 108 can be hung on the placement ring 106 for baking food.
[0048] Optionally, a metal disc 206 is fitted on the upper part of the fume hood 204, and the metal disc 206 is disposed at the bottom of the placement groove 107.
[0049] In this way, the metal plate 206 is fitted on the upper part of the flue hood 204 and set at the bottom of the placement slot 107 and the metal tag 108. The metal plate 206 can effectively catch dripping grease, reduce smoke generation, and is easy to clean, keeping the furnace clean.
[0050] Optionally, a sealing ring 109 is also provided on the upper part of the placement ring 106, and the sealing ring 109 is sleeved on the smoke pipe 205.
[0051] In this way, the sealing ring 109 on the upper part of the placement ring 106 can cover the space between the placement ring 106 and the flue 205, which can isolate the inside of the furnace body 100 from the outside, prevent heat loss, and improve heating efficiency.
[0052] Optionally, the damper 300 has a rectangular structure, and a baffle 301 is slidably inserted into the damper 300. A threaded rod 302 is rotatably provided on the upper part of the baffle 301, and the threaded rod 302 is threadedly connected to the side wall of the furnace body 100.
[0053] In this way, the absence of a rectangular structure in the damper 300 allows the baffle 301 to easily control the opening and closing of the damper 300, adjust the air intake, ensure complete combustion, and improve the heating effect. The threaded rod 302 is rotatably mounted on the baffle 301 and is threadedly connected to the furnace body 100. By rotating the threaded rod 302, the position of the baffle 301 can be adjusted, and the opening and closing of the damper 300 can be precisely controlled to achieve the best combustion state.
