Abstract:
A method of combusting a fuel in a furnace having four walls, comprising the steps of discharging fuel towards the center of the furnace, mounting an air nozzle to at least one of the walls, introducing air into the nozzle, providing a blade in the nozzle to split the air into two streams so that one of the streams discharges at an angle to the axis of the nozzle and along the inner surface of one of the walls, and so that the other stream discharges from the nozzle towards the center of the furnace to support the combustion of the fuel, and pivoting the blade to vary the quantity of air in each stream and vary the discharge angle of the one stream to insure that an oxidizing atmosphere is maintained along the one wall.
