Biomass gasification technology for power generation
Converting biomass into combustible gas and using it for power generation has emerged as means of converting abundantly available biomass wastes into clean and efficient electrical energy.
An advanced biomass gasification power plant typically involves a gasifier system converting solid biomass into clean combustible gas by thermo-chemical processes involving the stages of drying, pyrolysis and gasification. The non-combustible ash produced in the process migrates to the grate at the base of the gasifier and is removed from time to time with grate-shaking mechanism.
The produced syngas is burned in the oxidiser at temperature up to 700°F with the produced hot flue gas passing through a boiler to produce high-pressure steam that drives the turbine for producing electricity. Electrostatic precipitators are used to capture the remaining particulates present in the flue gas released into air.
