Product Introduction
Biomass gasification refers to the thermochemical process of converting biomass fuel into a combustible gas and producing charcoal. In this process, water vapor, free oxygen or combined oxygen is thermally chemically reacted with carbon in the fuel to form combustible gases such as carbon monoxide, hydrogen and low molecular hydrocarbons, and at the same time produce charcoal. The biomass gasification process is complicated, and the gasification reaction conditions are also different. However, all the gasification reaction processes basically include the drying, pyrolysis, oxidation and reduction processes of biomass.
 
Raw material requirements: moisture ≤ 20%, size ≤ 10cm
Features
1
The raw materials are widely used, wood chips, straw, pellet, rice husks, coconut shells, and mushroom dreg can be used.
2
By-product charcoal, tar, wood vinegar is of high value.
3
High automation, no need auxiliary fuel, plc intelligent control automatic induction feeding and ash discharging, automatic cleaning.
4
Stable gas production, continuous and stable operation for 24 hours.
5
The furnace body is well protected, using water circulation to cool down, emergency pneumatic explosion-proof.
6
The environmental protection advantages are obvious, and the emission of smoke, sulfur dioxide and nitrogen oxides is extremely low.
