NOVELTY - A new type efficient household motorless biomass gasified combustion furnace comprises bottom ash cabin (1), ash discharge hole (2), ash discharge control device (3), furnace body outer shell (4), furnace body inner shell (5), sealing device (6), bracket (7), feeding port (8), chimney (9), air jacket (10) and feeding device (11).    USE - The new type efficient household motorless biomass gasified combustion furnace is useful for industrial applications.    ADVANTAGE - The new type efficient household motorless biomass gasified combustion furnace adopts the structure of feeding on top, and blasting at the bottom and on the periphery, which can make the biomass gasified combustion integrate, to reach the biomass efficient gasified combustion; and without providing power for blasting by the outside and the design of other additional stoves, which has low cost, high efficiency, simple and safe operation, no tar treatment, and it is clean and healthy, adapted to the biomass fuel of many types such as the agricultural waste and cows, sheep, horse, donkey and manure of some fowls, and adapted to the large area rich in the biomass resource.    DETAILED DESCRIPTION - A new type efficient household motorless biomass gasified combustion furnace comprises bottom ash cabin (1), ash discharge hole (2), ash discharge control device (3), furnace body outer shell (4), furnace body inner shell (5), sealing device (6), bracket (7), feeding port (8), chimney (9), air jacket (10) and feeding device (11), where the main body of the combustion furnace adopts double-layered structure, the bottom ash cabin is located on the lowermost part of the whole furnace, on which is provided with an ash discharge hole, ash discharge control device and the feeding device, the furnace body outer shell and the furnace body inner shell both are installed above the bottom ash cabin, the part between the furnace body outer shell and the furnace body inner shell is the air jacket, the feeding port is opened on the furnace body inner shell of the furnace, and meanwhile a sealing device is installed between the furnace body outer shell and the furnace body inner shell, the upper part of the furnace can be installed with the bracket, and the chimney is connected with the furnace body outer shell and the furnace body inner shell.
