Current location: > Biomass Gasifier > FENGYU Fluid-bed Gasifier

FENGYU¡¯s fluid-bed biomass gasifier (patented product of Fengyu Group) gets high conversion efficiency, by taking rice husk as an example, each KWH power generation consumes only 1.6~1.8kg rice husk, the unit fuel consumption will be still lower by using wood chips or crop stalks as fuel. When operation temperature is 800, the tar production ratio in fluid bed gasification furnace is about 2.5%. Tar content after decoking treatment is less than 50mg/Nm3, through strict cleaning and thermal cracking, the dust & tar content of biomass gas are very tiny, which can meet the requirement for the internal-combustion engine and steam turbine normal operation.

Note£º
¡¡¡¡Main components and caloricity of biomass gas are subject to characteristic of biomass fuel and gasification method.
The caloricity of biomass gasification gas is normally 1100-1500kcal/Nm3. (4.6~6.3MJ/Nm3)
For example, main component of rice husk gasified gas are as follows:
comonent CO H2 CH4 CmHn H2S CO2 O2 N2
percentage 17.2 4.05 6.82 1.24 --- 15.1 0.8 54.7
(The caloricity is£º1393kcal/Nm3 (5.83 MJ/Nm3)
