International Classification:

F23Q 2/00

US Classification:

431254

Abstract:

A burner assembly including a housing having an air inlet and a burner end, a motor, and an impeller mounted in the housing. The impeller is in fluid communication with the air inlet, in mechanical communication with the motor, and adapted to direct air from the air inlet towards the burner end of the housing. The burner assembly also includes at least one pre-mix gas injection nozzle mounted in the housing. Each of the at least one pre-mix gas injection nozzle has at least one orifice adapted to direct gaseous fuel into the housing. The burner assembly further includes a spin vane comprising at least one spin vane blade. The spin vane is mounted in the burner end of the housing and adapted to direct the flow of air in the burner end. The burner assembly still further includes an igniter mounted in the burner end of the housing. The igniter is adapted to ignite the air and fuel mixture in the burner end of the housing to produce a main flame.

International Classification:

F23Q 900

US Classification:

431284, 431115, 431182, 431188, 431285

Abstract:

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.
