The utility model discloses the theory of operation: when no fuel is placed in the gasification chamber 104, the invention can be understood as a rocket stove with secondary and tertiary combustion, firewood placed in the combustion chamber 101, wood gas and flame generated after combustion and baking are continuously supplemented with external preheated air through the small holes 171 on the wall of the circular tube 17 in the cross passage 102 and the circular tube cavity 103, the wood gas is ignited, a rotating flame is obtained in the circular tube cavity 103, the flame is emitted from the top of the circular tube 17, an iron pan (not marked in the figure) at the top is heated for cooking, meanwhile, after the flame heats the heated tube 32 (for ventilation and heating) above the inside of the stove and the box body, tail gas is discharged from the conduit 22 (chimney interface), heat generated by combustion of the fuel stove (rocket stove) raises the temperature of the outer plate of the box body through radiation and convection of air, and then heating is carried out, and air flow is carried out in this way, the main air flow enters from an opening (not shown in the figure) arranged above the upper cover plate 12, passes through the combustion chamber 101, the cross passage 102 and the circular tube cavity 103 to the guide pipe 22 (chimney connector), simultaneously, part of air enters the gasification chamber 104 from the combustion chamber 101 through the square hole 502 on the middle clapboard 5, then passes through the respective openings of the U-shaped pipe 16 and the circular tube 17 to be merged with the main air flow to realize secondary combustion, simultaneously, the external air enters the air passage consisting of the two air guide plates 29 through the long slotted hole 501 on the middle clapboard 1, then enters the interior of the furnace through the respective small holes of the U-shaped pipe 16 and the circular tube 17 to be merged with the main air flow to form tertiary combustion.

After the fuel is added into the gasification chamber 104, under the influence of the heat generated by the combustion of the furnace, the fuel in the gasification chamber 104 undergoes a series of changes such as drying and dry distillation, etc., to generate a large amount of combustible gas, which is generally referred to as wood gas, and the wood gas, as mentioned above, enters the interior of the furnace in a small amount through the respective openings of the U-shaped tube 16 and the round tube 17 to participate in combustion, and generates a flame larger than that generated when a rocket furnace is used alone, without opening the upper cover plate 12.

At this time, by adjusting the corrugated handle 13 on the upper cover plate 12, the upper cover plate 12 is lifted up, a gap is formed between the upper cover plate 12 and the front plate 3, air enters into the combustion chamber 101 of the furnace except for the combustion chamber 101, and enters into the left channel 111 and the right channel 112 located at both sides of the combustion chamber 101 through the aforementioned gap, the left channel 111 enters into the channels of the transverse auxiliary air pipe 30 and the longitudinal auxiliary air pipe 31 through the notch 503 on the middle partition plate 5, enters into the gasification chamber 104 through the through holes (not labeled in the figure) on the transverse auxiliary air pipe 30 and the longitudinal auxiliary air pipe 31, the right channel 112 directly enters into the gasification chamber 104 through the smaller guide hole on the middle partition plate 5, the air intake amount of the two parts is controlled by the corrugated handle 13, when the air intake amount is larger than the air intake amount entering into the furnace from the respective small holes of the U-shaped pipe 16 and the circular pipe 17, the generated wood gas enters into the combustion chamber, the back combustion is realized, and the air flow is self-circulated by adjusting the air inflow, so that the input amount of fuel (long firewood) in a combustion chamber is reduced, and the corresponding work of the biomass fuel furnace for heating is finally completed.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modification, equivalent replacement or improvement made within the spirit and principle of the present invention should be included in the present invention.
