gasifier, biomass gasifier

Biomass gasification means that biomass gasification raw materials (such as straw, wood chips, rice husks, etc.) are pressed into shape or subjected to simple crushing and drying processing, and then sent to the gasification furnace for gasification and cracking under oxygen-deficient conditions. , that is, under certain thermodynamic conditions, with the help of part of the air (or oxygen) and water vapor, the biomass polymer undergoes pyrolysis, oxidation, reduction, and reforming reactions, and the tar associated with pyrolysis is further thermally cracked. Or the process of catalytically cracking small molecular hydrocarbons to obtain combustible gases containing,

. Advantages of biomass gas (biomass gasification gas)

. In addition to the general characteristics of biomass fuel, biomass gas also has the following features Advantages:
.
. ▲ Environmentally friendly and clean gas fuel
.
. ▲ Good combustion characteristics and high burnout rate
.
. ▲ Contains sulfur The amount of nitrogen is extremely low, only about/about that of fuel oil. It can meet environmental protection requirements without taking any desulfurization measures
.
. ▲ The nitrogen content is extremely low, and it can meet environmental protection requirements without taking any denitrification measures during combustion. Requirements
.
. ▲ Low ash content
.
. ▲Emissions: biomass burning emissions
.
.
.
. The same, and it replaces fossil energy and reduces net emissions. According to the "Kyoto Protocol" mechanism, biomass fuel
.
. is an ecological emission.

. Application of biomass gasifier and biomass gas


. Biomass gas, that is, biomass raw materials in Through high-temperature gasification in the biomass gasifier, it is converted into biomass combustible gas, which can be used in steel kilns, glass kilns, and ceramic kilns instead of fuel oil or natural gas.
.
. The quality of biomass gas is basically the same as the current industrial coal-to-gas (water gas), but the dust and tar content are lower and more environmentally friendly.
.
. Biomass gas is a very clean domestic and industrial fuel. Unpurified biomass gas fuel can be directly transported through pipelines and applied to steel-rolling heating furnaces, copper-smelting reverberatory furnaces, and crucibles. After purification processes such as dust removal and coking are carried out on boilers, industrial boilers, cement rotary kilns, refractory tunnel kilns and other industrial kilns with lower fuel quality requirements, their application scope can be extended to ceramic kilns, glass kilns, hot blast stoves and In industrial kilns with high fuel quality requirements such as power plants.
