Abstract

The invention provides an auxiliary fire device for a gas burner. An insulating base is connected to one end of a metal pipe, and a projection with a blind hole is arranged on a seal cover which is arranged at one end, close to the insulating base, of the metal pipe. The side wall of the projection is provided with a hybrid gas outlet. The auxiliary fire device for the gas burner has the advantages that the seal cover, the projection and a metal wire form a thermocouple, and the metal wire and a fusion point between the metal wire and a top cover cannot be directly burned by flames, so that service life of the thermocouple is prolonged; in addition, the metal wire, the seal cover, the projection and the fusion point between the metal wire and the top cover can be constantly and completely cooled by air flow, generation of temperature difference potential is benefited to realize amplification of monitoring sensible capacity, high stability and reliability in monitoring are achieved, and misoperation can be avoided.

Description

technical field [0001] The invention relates to the technical field of gas burner equipment, in particular to a sub-fire device for a commercial blower type gas burner with a flameout protection device. Background technique [0002] The burner is a thermal energy device that sends fuel and air into the furnace according to the required concentration, speed, turbulence and mixing method, and enables the fuel to ignite and burn stably in the furnace. [0003] At present, the ignition part of a commonly used commercial blast burner includes a sub-ignition device and a flameout protection device. Among them, the sub-ignition device is used to provide the fire source, and the flameout protection device is used to cut off the gas source in the case of accidental flameout. When in use, the sub-fire device (blast type) is ignited, and the main fire burner is ignited through its fire source. The flameout protection device includes a thermocouple, which monitors the continuity of the...
