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 a plurality of gas injection tubes that are disposed substantially parallel to each other. Each of the plurality of gas injection tubes includes a tube inlet end, a tube outlet end and at least one aperture. In addition, the burner assembly includes a first tube sheet disposed near the tube inlet ends of the plurality of gas injection tubes and a second tube sheet disposed near the tube outlet ends of the plurality of gas injection tubes. The burner assembly further includes a spin vane having 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…
