A burner assembly including a housing having an air inlet, a burner end having an opening, a longitudinal axis extending generally from the air inlet toward the burner end, a motor, an impeller mounted in the housing and being in fluid communication with the air inlet, operatively connected to the motor and adapted to direct air from the air inlet toward the burner end, a coal tube adapted to convey coal toward the burner end, a coal inlet adapted to convey coal to the coal tube, a first bluff body ring, a second bluff body ring and a third bluff body ring mounted at the burner end, a flame bridge disposed between the first bluff body ring and the second bluff body ring, and an igniter mounted in the burner end and being adapted to ignite the air and fuel mixture in the burner end to produce a main flame.

Coal burner assembly

A burner assembly including a housing having an air inlet and a burner end. An impeller that is mounted in the housing is in communication with the air inlet and adapted to direct air toward the burner end of the housing. The burner assembly also includes an inner air tube that is mounted in the burner end of the housing so as to define an inner combustion zone and an outer combustion zone. The assembly further includes a plurality of radiation plates that are mounted in the burner end of the housing adjacent to the outer combustion zone, an inner air spin vane that is mounted on the inner air tube so as to direct some of the air from the impeller into the inner combustion zone, an inner gas injection nozzle mounted on the inner air tube so as to direct gaseous fuel into the inner combustion zone, an outer air spin vane that is mounted in the burner end of the housing so as to direct some of the air from the impeller into the outer combustion zone, and a plurality of outer gas injection nozzles that are mounted in the burner end of the housing so as to direct gaseous fuel into the outer combustion zone. A first castellated ring is mounted around the periphery of the inner air tube, and a second castellated ring is mounted around the periphery of the burner end of the housing.
