Abstract:
An atmospheric gas burner assembly producing relatively low oxides of nitrogen (NO. sub. x) emissions comprising a gas-air feed tube communicating with a burner chamber portion provided with an apertured inner burner distribution plate member having a multiplicity of relatively large size outlet apertures for distributing the gas-air mixture outwardly from the burner chamber portion, an intermediate burner port plate member overlying the apertured distribution plate member in spaced relation thereto and provided with a multiplicity of relatively small size burner port outlets for issuing outwardly therefrom small gas-air streams which combust to form a low temperature, low flame front profile over the outer surface of the burner port plate member, and an outer screen mantle member of woven stainless steel wire cloth of fine mesh overlying the burner port plate member is closely spaced relation thereto and positioned within the tip ends of the flame front issuing from the burner port plate member to become heated to an infrared radiant heat emitting condition. A turbulator member is positioned within the venturi tube to create turbulence of the fuel-air mixture passing therethrough to minimize resonance thereof during burner operation.
