PILOT BURNER AND PILOT BURNER GAS NOZZLE UTILIZING THE SAME

摘要

A pilot burner capable of being used as both a pilot burner and a gas nozzle having the piloting function for a main burner, the dimensions of this pilot burner being reduced by omitting an ignition rod. This pilot burner (1) has a conductive outer cylinder (7), and a conductive inner cylinder (9) housed in an electrically insulated state in the outer cylinder (7). A high voltage is applied between the outer cylinder (7) used as an earth electrode and the inner cylinder (9) used as a high-voltage electrode, to produce sparks into spark gaps (39) in the vicinity of air ejection ports (37) and ignite a diffused mixed gas occurring in the vicinity of the ejection ports (37), whereby pilot flames (45) are generated. A diffused mixed gas occurring on the further downstream side is burnt with these pilot flames (45).
