A solid fuel boiler or furnace with a flue gas-air mixture introduced into the fuel grate is disclosed. The flue gas is mixed with air such that approximately 30% of the mixture is flue gas. By providing this mixture under the burning fuel bed, the temperature of the fuel bed is lowered and excess oxygen is reduced. A more reactive fuel bed results providing various advantages including improved boiler operation and a clinker-free fuel bed. |
