Abstract
A gaseous fuel burner with a base formed of cast aluminum and a wafer cooperating with the base for forming an annular of flame generating ports. A cap is received over the wafer and forms a dead air space for reducing the temperature rise of the cap. The wafer and base are formed of aluminum or brass and the cap is either formed of cast iron or cast aluminum with a porcelainized steel disc insert on the upper surface.
Claims14
A burner assembly for gaseous fuel comprising:
- (a) a body formed of a metallic material having a melting point less than the ignition temperature of said fuel and having an annular configuration with an inlet adapted for connection to a source of gaseous fuel and air and communicating with a cavity defined by a portion distal said inlet;
- (b) a wafer disposed over said cavity and closing same to form a fuel-air plenum chamber and cooperating with said base to define a plurality of peripheral flame generating ports each communicating with said fuel-air plenum chamber;
- and,
- (c) a cap formed substantially of metallic material and disposed over said wafer, said cap and wafer defining therebetween an air plenum for limiting the temperature rise of said cap.
