Description

technical field [0001] The invention relates to a biomass gasification system. Background technique [0002] With the development of economy and society, we are facing enormous energy and environmental pressure. The raw materials of combustible gas produced by the biomass gasifier are crop straws, forest wastes, etc. This kind of gas is a green new energy with strong vitality. It is a very important renewable energy with renewability and low pollution. and wide distribution. The use of biomass as an alternative energy source is of great significance to low-carbon emission reduction, reduction of "greenhouse effect" and improvement of atmospheric acid rain environment. Biomass gasification system is to use biomass to burn in a closed anoxic furnace in a gasifier, and produce combustible gas after dry distillation, pyrolysis and thermochemical oxidation. [0003] Chinese patent 201410453965.6 discloses a tower-type biomass gasifier, which includes a furnace body, a feeding ...
