Problems solved by technology

[0002] Existing biomass gasification furnaces are all made of steel into a cylindrical or cone shape by welding, stamping, machining and other processes. This kind of biomass gasification furnace consumes a lot of steel, and the processing is complicated and costly. , Corrosion, short life, uneven oxygen supply, unstable gas production, slow ignition speed, and the top air bed is easy to temper, which poses serious safety hazards, tar discharge pollutes the environment, poor heat preservation effect, and insufficient combustion temperature in the combustion zone to produce gas Low
Some are processed into interlayers to make water heaters. The water heated by this method is almost dirty water, which is very unhygienic.
