BIOMASS-BASED POWER GENERATION:DIRECT FIRING

The stoker grate was first developed for coal combustion in the 1920s and in the 1940s the Detroit Stoker Co. designed a stoker boiler for wood combustion. Fuel is distributed more evenly in a stoke grate than in a pile burner, allow- ing more efficient combustion. Air still enters the furnace from beneath the grate and this air flow cools the
