AI Technical Summary

Technical Problem

In the existing combined plasma ignition device, the plasma arc discharge arc is short and it is difficult to meet the ignition requirements in complex environments. In addition, traditional methods increase the arc length, there is a risk of ultra-high voltage, which is difficult to design and high cost.

Method used

A multi-point plasma arc ignition device is designed, including fixed and mobile plasma arc ignition guns, which increases the arc length by strengthening the arc hood structure and uses a multi-point coverage mode to improve the ignition success rate.

Benefits of technology

The arc length is effectively increased, extending it from 1~6cm to 15~20cm, improving the ignition success rate. Especially in harsh environments, it can effectively ignite combustible gases and reduce the risk of artificial ignition.
