Biomass Boiler - an overview | ScienceDirect Topics

In a typical biomass boiler the biomass surface temperature increases to 130°160°C during the first couple of milliseconds after its insertion into the furnace. As water is evaporated starting from the surface the wet core size decreases. Typically the biomass particle is not completely dry at the center when the volatiles release starts close to the surface.

Fly Ash Penetration through Electrostatic Precipitator and ...

Oct 03 2002 · The effects of an electrostatic precipitator and a flue gas condenser on size resolved fly ash particle concentration and composition were studied in a 6 MW biomass combustion unit fired with moist forest residue. The boiler was of moving grate type. The fly ash particles were sampled upstream and downstream of the electrostatic precipitator and flue gas condenser respectively.
