[0002] A gasification combustion furnace is a device that converts solid fuels (such as wood, coal, biomass, etc.) into combustible gases and uses these gases for combustion to generate heat energy or power. The working principle of the gasification combustion furnace is based on the gasification process of the fuel. By controlling the supply of oxygen, the fuel is partially oxidized and decomposed into combustible carbon monoxide (CO), hydrogen (H2), and other combustible gases, and then these gases are burned to obtain a higher energy output.

[0003] Traditional coal and firewood stoves usually adopt a direct combustion method and lack an effective combustion control mechanism. The fuel often cannot be fully burned, resulting in a large amount of energy waste. Secondly, due to incomplete combustion, more fuel needs to be consumed to achieve the expected heat energy output, which not only increases the use cost but also exacerbates the consumption of resources. Content of the Utility Model

Of course, they are only examples and are not intended to limit the embodiments of the present utility model. In addition, the embodiments of the present utility model may repeat reference numerals and / or reference letters in different examples. This repetition is for the purpose of simplification and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0034] To better understand the purpose, structure, and function of the present utility model, the coal-fire and wood-fire dual-use high-efficiency energy-saving and environmental protection gasification combustion furnace of the present utility model will be further described in detail below with reference to the drawings.

[0035] As Figures 1-9 shown, the coal-fire and wood-fire dual-use high-efficiency energy-saving and environmental protection gasification combustion furnace of the present utility model includes a housing 100, and a flue 7 is provided at one end of the housing 100.

[0036] Inside the housing 100, there are a combustion chamber 3 and a slag discharge chamber. The combustion chamber 3 and the slag discharge chamber are separated by a hollow plate 20. One side of the combustion chamber 3 is connected to the furnace body feed inlet. Coal or wood enters the interior of the combustion chamber 3 through the furnace body feed hopper, and the fuel can burn on the hollow plate 20.

[0037] A furnace door cover 1 is arranged outside the furnace body feed inlet. The furnace door cover 1 is fixed by a furnace door cover locking member 16. The furnace door cover locking member 16 is a rotating handle and a locking buckle on the handle. The furnace door cover 1 can be fixed by buckling the locking buckle on the locking rod of the furnace door cover 1, improving the safety during the use of the device.

[0038] A smoke baffle 21 is rotatably arranged inside the furnace body feed inlet. The smoke baffle 21 partially blocks the smoke generated by the combustion in the combustion chamber 3 to prevent backflow. When it is necessary to observe or discharge materials, the smoke baffle 21 can be pushed inward to make the smoke baffle 21 inclined.

[0039] And oxygen-increasing and combustion-assisting intake channels 15 are provided on both sides of the housing 100. Siphon combustion-assisting intake channels 12 communicating with the combustion chamber 3 are provided on the inner wall of the oxygen-increasing and combustion-assisting intake channels 15. The siphon combustion-assisting intake channels 12 have 2 holes and oxygen-increasing and gasification combustion-assisting intake channels 13, with a total of 11 holes. A primary intake front channel 11 and a primary intake rear channel 14 are provided in the upper part of the slag discharge chamber.

[0040] An adjustment groove 22 is provided on one side of the slag discharge chamber. A primary combustion intake adjustment rod 17 is slidably connected in the adjustment groove 22. One end of the primary combustion intake adjustment rod 17 located in the slag discharge chamber is connected to a primary intake adjustment plate 10. At the same time, a long rod 23 is connected to the lower end on one side of the primary intake adjustment plate 10. The long rod 23 penetrates through the housing 100 and extends to the outside.

[0041] When the fuel in the combustion chamber 3 is ignited for 20 - 60 minutes to burn out the mold release grease carried by the furnace lining when the furnace lining is removed from the mold, and the flue 7 does not emit black smoke, it is in the best state. At this time, fuel is added. The fuel cannot exceed the vertical plate of the furnace temperature increase protection device 4 installed on the inner wall of the combustion chamber 3. Otherwise, substances that are not completely burned will be discharged, and at this time, the chimney smoke emission does not meet the standard;

[0042] After adding fuel, close the furnace door cover 1. At this time, the furnace door cover 1 cannot be opened, otherwise smoke will be discharged. After the fuel burns normally, if necessary, the furnace door cover 1 can be opened to observe the combustion state or stack the fuel in an orderly manner.

[0043] When adjusting the small fire and large fire states through the primary intake adjustment plate 10, the primary combustion intake adjustment rod 17 pushes the primary intake adjustment plate 10 towards the flue 7 for the small fire combustion state, and pushes it towards the furnace door for the large fire combustion state. When it is pushed to the extreme position towards the flue 7, it is in the siphon type high-efficiency energy-saving carbonization combustion state. At this time, the heat dissipated by the furnace is not very high, and it can be adjusted according to the room temperature.

[0044] When the fuel burns to a certain state, the slag discharge chamber side wall at the upper end of the ash hopper 9 is movably installed with a ash shaking device 8 to remove the ash after combustion. The ash shaking device 8 is used to reciprocally push the hollow plate 20, so that the ash falls downward into the ash hopper 9 movably arranged at the bottom of the slag discharge chamber, and the ash is poured out by using the ash hopper 9.

[0045] And the dust generated during fuel combustion is isolated by the dust filter plate 6 arranged inside the combustion chamber 3 to prevent the dust from floating out through the flue 7. In addition, a furnace lining heat preservation member 19 is arranged on the outer wall of the combustion chamber 3 on the other side of the dust filter plate 6, which protects three sides except the furnace door direction and has the functions of preventing heat loss from being too fast and extending the service life of the furnace lining.

[0046] An oven 2 is arranged at the upper end outside the combustion chamber 3, which can be used for baking food.

[0047] The opening formed at the top of the combustion chamber 3 is sealed by a fire sealing cover 5. When using the fire sealing cover 5 at night, by restricting the exhaust gas discharge flow rate, the furnace chamber can achieve a low-energy consumption combustion state with the fire kept.

[0048] After using for one season, when the furnace is stopped, an ash cleaning device 18 is arranged at the lower end of the housing 100 of the flue 7. The ash cleaning device 18 is a sealing plate fixed by bolts to remove the accumulated ash inside. At the same time, the furnace should not be stored in a humid environment.

[0049] Working principle of the coal and firewood dual-purpose high-efficiency energy-saving and environmental protection gasification combustion furnace: By adjusting the opening sizes of the primary air inlet front channel 11 and the primary air inlet rear channel 14 through the primary air inlet regulating plate 10, the fuel burns once. The siphon-assisted combustion air inlet channel 12 is used for air intake to assist secondary combustion, and the oxygen-increasing gasification-assisted combustion air inlet channel 13 is used for tertiary combustion, so that the device can fully burn the fuel, make the discharged waste gas meet the environmental protection standards, and save more fuel than traditional furnaces. When the primary air inlet front channel 11 and the primary air inlet rear channel 14 at the bottom are closed, the device is in a siphon-type super energy-saving carbonization combustion state. When adding the fire sealing cover 5 at night, through the control of the exhaust gas discharge port flow rate, a low-energy consumption combustion state with the fire kept is realized.

[0050] It can be understood that the present utility model is described through some embodiments. Those skilled in the art know that without departing from the spirit and scope of the present utility model, various changes or equivalent replacements can be made to these features and embodiments. In addition, under the teaching of the present utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present utility model.
