ABSTRACT:
Apparatus and method for burning green wood chips in which the hot combustion gases generated by the burning of the chips in a furnace are passed through chips in a storage silo from which the chips are subsequently fed to the furnace. A column of chips of substantial height is maintained in a top vented silo. Chips are fed from the lower portion of the column to the furnace and usually mixed with other fuel such as particulate coal or coal dust, and the hot combustion gases from this combustion are fed into the silo at a location substantially below the top of the column of chips so that the gases permeate and pass upwardly through the column of chips to dry them. The chips also act as a filter to remove environmental contaminants from the gases.
