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.Get Price
