Abstract:

A method and apparatus are provided for treating exhaust from a solid fuel combustion system such as a furnace or boiler and includes combusting a material in the combustion chamber and separating fly ash and char from a flue gas stream. The separated fly ash and char mixture is then separated further by separating smaller ash particles from larger char particles. The larger char particles are then reduced in size by a reducing device such as a grinder or crusher. Char particles that have been reduced in size by the grinder or crusher are then reinjected into the combustion chamber for re-burning.
