(2) The utility model discloses a plurality of secondaries that water tank inside set up upper end intercommunication second combustion chamber lower extreme intercommunication ash bin give the tuber pipe, and the firework that gets into the second combustion chamber obtains the secondary and gives the oxygen suppliment of wind, and the further abundant burning of insufficient firework of burning has improved the thermal efficiency of biomass combustion, is favorable to reducing the emission of harmful gas such as carbon dioxide.

(3) The utility model discloses the secondary is given tuber pipe lower extreme intercommunication in the ash bin, and the ash drawer that pulls open is opened the secondary and is given wind, closes the ash drawer and just closes the secondary and give wind, can control the secondary through push-and-pull ash drawer and give wind. Thereby conveniently controlling the heating temperature of the boiler.

(4) The utility model discloses combustion chamber upper portion is equipped with sits the pot mouth, and the combustion chamber front side is equipped with furnace gate mouth and furnace gate, and the combustion chamber inner space is bigger, is fit for burning biomass fuel such as straw, ox sheep manure, straw, rice husk, peanut shell, corncob, cottonseed shell, and overall structure is simple moreover, and low in cost is particularly suitable for using widely in rural pastoral area.
