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,…
