Wood gasifier also belongs to forest waste gasification power system and is a kind of biomass gasification. The main raw materials used in wood gasifier are all kinds of waste wood. The gasification process of wood gasifier is a process of producing combustible gas by pyrolysis and oxidation at high temperature. Wood gasifier system can also be called wood gas producing equipment, which is a new type of environmental protection equipment.
In the process of wood gasification, wood should be dried as a fuel, the moisture will be below 20%, and the wood will be broken into a size of about 30mm, and then enter the gasifier to form a synthesis through pyrolysis of biomass, oxidation, reduction and other reactions. After the syngas is purified by the dust collector, the clean gas can be used for docking biomass power plant, biomass dryer and other equipment.
Wood gas power generation system also belongs to biomass gas power generation system. Wood, as a biomass raw material fuel, is pyrolyzed or gasified at high temperature to produce a flammable gas. Biomass gases are mainly CO, H2, and a small amount of methane. Other components include tar, solid carbon particles, moisture, etc. Wood has a higher calorific value, so it has a higher calorific value. It is a better biomass fuel. Wood gas power generation is also called wood gasification power generation.
