[0002] A biomass gasifier is a device that converts biomass raw materials into combustible gas. It can obtain higher fuel efficiency from low-cost biomass raw materials, is green and environmentally friendly, and has excellent economic advantages. The fuel gas produced by the biomass gasifier is a renewable, environmentally friendly and clean energy source. Its main components include carbon monoxide, hydrogen and methane, as well as some high-molecular hydrocarbons and a small amount of tar. Under the action of airflow, flue gas and dust will be mixed into the fuel gas, affecting the purity of the fuel gas. The fuel gas needs to be purified.
