发明名称 Gas burner
摘要 A gas burner capable of automatically shutting off the supply of a gas fuel when the content of the oxygen in the air supplied to the gas burner drops to a predetermined level. It incorporates a Smithell's gas burner as a pilot burner which consists of an inner tube and an outer tube formed with an auxiliary air port. The sizes of these inner and outer tubes as well as the diameter and position of the auxiliary air port are so selected that when the contents of the oxygen in the air supplied to the gas burner drops to a predetermined level, the inner flame cone at the mouth of the inner tube is blown off. A sensor is provided which detects the blown off and generates the output signal in response to which a control means such as a solenoid-operated control valve may close the gas supply pipe. The pilot burner is of the general type in that it can burn gas fuels having different heating values.
