Description

Redundant high-energy igniter

Technical Field

The utility model relates to a high energy ignition device field for gas boiler especially relates to a redundant high energy point firearm.

Background

At present, high-energy ignition devices for gas boilers are all configured in a one-to-one manner, namely, one ignition rod is provided with one high-energy igniter, the high-energy ignition device needs to be frequently started to emit electric sparks to ignite gas thrown into a boiler at the initial commissioning stage of the boiler, the high-energy ignition device quits working after ignition is successful, the situation of unstable fuel quality or low load can be avoided in the operation process of the boiler, and at the moment, in order to achieve the effect of stable combustion, the high-energy ignition device needs to be started again to ignite, so that the ignition of the fuel can be ensured. Because the gas explosion limit is low, the ignition success rate of the gas boiler is particularly important, the ignition frequency of each high-energy igniter has a certain service life, and certain potential safety hazards exist when the single-configuration high-energy igniter is used for ignition of the gas boiler.
