The utility model discloses a
biomass gasifier, belonging to the technical field of
biomass gasifiers, which comprises a gasification furnace body, and an annular
air chamber is fixedly sleeved on the outer side of the gasification furnace body. In the utility model, a gas distribution ring is installed in the inner cavity of the gasification furnace body through two rolling bearings. Through the cooperation of the gas distribution ring and the inclined ring, the influence of the air inlet device on the feeding and
combustion of
biomass fuel in the gasification furnace body is avoided. In addition, air is introduced into the inner cavity of the annular
air chamber from the air inlet
pipe, and the air in the annular
air chamber enters the inner cavity of the gasification furnace body through the outer air inlet holes and the inner air inlet holes. At the same time, a
servo motor is used to drive the straight gear to rotate, and the gas distribution ring is driven to rotate through the meshing transmission between the straight gear and the annular tooth seat, so as to change the position of the inner air inlet holes on the gas distribution ring, and further change the direction of air entering the gasification furnace body, thereby improving the practicability of the air inlet device of the
biomass gasifier.
