Novel zero discharge environment-friendly biomass gasification furnace

The utility model relates to a biomass gasification furnace, in particular to a novel zero discharge environment-friendly biomass gasification furnace, and solves the problems of low gas production quality, environment pollution caused by combustion products and the like of the existing biomass gasification furnace. The novel zero discharge environment-friendly biomass gasification furnace comprises a furnace cylinder and a furnace cover. The upper part of the furnace cylinder is provided with a fuel gas output pipeline. The lower part of the furnace cylinder is provided with an air supply device and a grate which divides the inside of the furnace cylinder into a gasification chamber and a dust chamber. The air supply device consists of an air supply pipeline and an air distributor arranged on the lower part of the gasification chamber. The air distributor comprises an upper circular plate, a lower circular plate and air guide plates between the two circulate plates. A through hole is formed in the center of
