Specifically, the top of the combustion chamber 11 of the combustion furnace body 10 adopts a flip-top type.

[0028] The utility model is provided with feeding components 40 on both sides of the outside of the combustion furnace body 10 to realize automatic feeding of biomass fuel; a connecting component 30 is provided at the furnace 12 to connect with the boiling component 20, and appropriate air can be continuously blown into the furnace 12 of the combustion furnace, so that the air in the furnace 12 is sufficient, the fire continues to burn vigorously, and the biomass fuel is fully burned; the combustion furnace can reach the required heat and provide the required heat to the dryer.
