OSTI ID:6416898
Capable of automatic fuel shutoff at preset combustion-air oxygen levels, this gas-fired water-heater burner incorporates a Smithell's pilot burner consisting of inner and outer tubes formed with an auxiliary air port. The tube sizes and the air port's diameter and position cause the inner flame cone at the mouth of the inner tube to be blown out when the oxygen content of the air supply drops to a predetermined point. A sensor detects the blowout and signals a valve to close the gas supply pipe to avoid incomplete combustion and hazardous carbon monoxide accumulations. The pilot burner can accommodate gases of different calorific values.
