NOVELTY - A straw gasification furnace device comprises a bucket furnace body (1), a furnace opening cover (4) for upper end filling, gas outlet (9) on side wall on upper part of the furnace body, gas inlet pipe (5) on lower part of the furnace body and ash holes (6) working as fore-leading port as well, and external water-gas separators (10); where the pipe head end face and pipe wall in the gas inlet pipe (5) of the furnace body are equipped with air holes; and there are at least two ash holes (6) respectively equipped on side walls on front and back sides on lower part of the furnace body.    USE - The straw gasification furnace device is useful for generating fuel gas.    ADVANTAGE - The straw gasification furnace device is able to discharge ash residues in the furnace from multiple angles which is convenient for ash discharging; ashes are cleanly and thoroughly discharged; newly added straw material is effectively sent to a gasification chamber on lower part of the furnace body; porous air inlet pipe head is able to send air into the furnace steadily and evenly which guarantees stability of gas production of the gasification furnace.    DETAILED DESCRIPTION - A straw gasification furnace device comprises a bucket furnace body (1), a furnace opening cover (4) for upper end filling, gas outlet (9) on side wall on upper part of the furnace body, gas inlet pipe (5) on lower part of the furnace body and ash holes (6) working as fore-leading port as well, and external water-gas separators (10); where the gas inlet pipe (5) is extended in perpendicularly upward from middle position of substrate of the furnace body; pipe head end face and pipe wall in the gas inlet pipe (5) of the furnace body are equipped with air holes; and there are at least two ash holes (6) respectively equipped on side walls on front and back sides on lower part of the furnace body.
