Compared with the prior art, the utility model has the following advantages:

(1) Simple and compact structure, small footprint, easy to use. The top of the silo has a concave groove structure, which is filled with water, and after being covered with a cover, it acts as a seal to prevent gas from leaking from the top of the silo.

(2) Since the adjustable baffle is installed between the gasification chamber and the door-type gas mixing combustion chamber, the opening of the baffle can be adjusted according to the type of biomass, so that the combustible gas is burned out and the exhausted smoke is colorless , tasteless, no smoke, safe and environmentally friendly.

(3) The gasification chamber, the portal-type gas mixing combustion chamber, the distance between the stove and the stove are small, and the flame at the stove mouth is the strongest. The combustible gas comes out from the portal-type gas mixing combustion chamber, and enters the uphill-shaped stove in an upward swirl and then returns to the flame and Air contact, further burnout, energy-saving effect is obvious.

(4) Use radiant heat to heat the water in the water jacket to 90-100°C, which can be used as hot water for washing, scrubbing and bathing, and the heat utilization is sufficient and reasonable.
