Patent ID: 7566218

Claim:
A burner assembly for mounting in a housing and forming an annular space therebetween, the burner assembly having a nozzle tip mounted in a burner head at a first distal end of a tubular barrel, the tubular barrel having a primary combustion air inlet and a fuel inlet at a second proximal end for providing a flow of primary combustion air and fuel in the tubular barrel directed toward the nozzle tip and a flow of secondary combustion air in the annular space directed towards the nozzle tip, the burner assembly comprising: means deflecting the flow of secondary combustion air in the annular space away from at least the nozzle tip for substantially separating the flaw of primary combustion air and fuel from the flow of secondary combustion air creating an area of low pressure at the nozzle tip relative to a pressure of the secondary air in the annulus whereby lifting of the flame from the nozzle tip is reduced and at least a portion of the flame is stabilized thereon.
