GASEOUS FUEL BURNER WITH REDUCED VELOCITY FLAME GENERATING PORTS |
摘要 |
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 primary-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.
