Ignition gun for industrial combustor

Abstract

The invention relates to an ignition gun for an industrial burner comprising a center pipe, an outer casing pipe, an igniting electrode, an insulation support and a transitional connector. On the insulation support, a center installation hole and an air flow hole are provided; the metallic pipe casing of the center pipe is connected with an igniting hi-pressure generator; the front end of the center pipe is provided with an igniting gun head nozzle block with a slant spraying hole; the metallic pipe wall of the outer casing pipe is provided with an entrance pipe for the combustion-supporting air; the center pipe is limited by the insulation support in the outer casing pipe. At operation, the metallic casing of the center pipe acts as a positive pole, the metallic casing of the outer casing pipe acts as a grounding negative pole, the inner of the center pipe is the channel for the gas fuel, and the space between the center pipe and the outer casing pipe is the channel for the combustion-supporting air; the gas fuel entered into the center pipe jets in a plurality of whiffs in dispersed way after passing the slant nozzles on the nozzle block; a discharging spark first fires one whiff and then the fired whiff ignites other whiffs to form a thick and long igniting torch. The invention is of simple and reasonable structure, works reliably and is of long service life, and is highly practical.

Description

technical field [0001] The invention relates to the technical field of gas combustion, in particular to an industrial burner ignition gun which has strong working stability and can generate a reliable ignition torch. Background technique [0002] At present, there are two types of ignition guns used on industrial burners: [0003] One type is the type with combustion air, which is mainly composed of a central tube, an outer tube, an ignition electrode, a high-voltage wire, and an insulating bracket with a central mounting hole and an airflow hole. The central tube is limited by the central mounting hole on the insulating bracket, and the set is set In the cavity of the outer casing, the high-voltage wire is arranged in the cavity between the central tube and the outer casing, one end of which is electrically connected to the ignition high-voltage generator, and the other end is electrically connected to the ignition electrode. The insulating bracket that isolates and insulat...
