Abstract

The utility model provides a biomass gasification furnace with a furnace barrel manually or electrically driven to rotate to assist blanking. In the technical scheme, the upper end of a furnace cover is provided with a gas outlet, the furnace cover covers in a water tank on the outer side of a feed port at the upper end of a furnace barrel in an embedding way and is supported by a bracket so that a certain clearance is respectively formed between the inner side and the outer side of the lower part of the furnace cover and the inner side and the outer side of the water tank at the upper end of the furnace barrel and between the lower end face of the furnace cover and the bottom surface of the water tank, and the lower end of the furnace barrel is embedded in a water tank on the periphery of the upper end of a furnace base so that the furnace barrel can be rotated flexibly between the furnace base and the furnace cover. When the furnace barrel is rotated, fuels at the upper end of the hearth in the high-temperature area of the furnace barrel can be continuously stirred for filling and blanking via a blanking shovel head which is fixedly connected with an air intake pipe in the furnace base, thereby realizing the continuous and stable gas production and significantly extending the uninterrupted high-fire burning time. The utility model has wide fuel sources but low requirements for the size and dryness of biomass fuels, and can be used and easily promoted in areas with sufficient or insufficient biomass waste fuels and crushed materials.
