A cast aluminum burner base has a tubular inlet communicating with a cavity formed in an enlarged diameter flange remote from the inlet. The cavity is closed by a cast aluminum cap registered against the base. The base and cap are each castellated along the parting line such that the castellations are interdigitated. Grooves having semi-circular cross sections and formed radially across the castellations and the spaces between and close on the parting line to form circular cross section primary flame-generating ports. The castellations on the cap are truncated and tapered to provide flame stabilizing passages adjacent alternate flame-generating ports. The grooves forming the primary flame generating ports are configured to preferably form a converging-diverging nozzle; and, the flame stabilizing passages are formed as a diverging nozzle, both for reducing flow velocity to pressurize flame separation.

Gaseous fuel burner with reduced velocity flame generating ports

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.

Gaseous fuel burner

A gaseous fuel burner having an annular base with a tubular inlet and enlarged diameter flange remote from the inlet deferring a cavity communicating with the inlet. A cap is registered against the flange rim to close the cavity and define a plurality of peripheral flame-generating ports. A pocket is formed in the periphery of the flange with an aperture formed in the pocket. A tubular ceramic igniter body with an enlarged flanged end is registered in the aperture. An elongated strip electrode is received through the igniter body in guideways; and, one end of the electrode is bifurcated and extends beyond the flange and is found at generally right angles to extend in spaced parallel arrangement with the face of the ignitor body flange for sparks discharge to the burner cap.
