一、前言 目前工业炉窑上使用的煤气点火装置种类很多,主要有小火点火(即长明灯式),热丝点火以及电火花点火等装置。国外在一般性的工业炉窑上煤气点火较普遍地采用了高压脉冲电点火装置,国内在燃气锅炉、中低温炉窑及焙烘箱上也陆续地采用了高压脉 冲电点火装置。它的优点在于可以采用自控程序及熄火报警系统使煤气点火自动化,提高了点火的可靠性及安全性,但是为了能产生可靠的电火花,需注意电压发生器的设
I. Introduction At present, there are many types of gas ignition devices used on industrial furnaces, mainly including small fire ignition (long light type), hot wire ignition and spark ignition. Abroad in the general industrial furnace gas ignition more commonly used high-voltage pulse electric ignition device, the domestic gas-fired boilers, medium and low temperature furnaces and baking ovens have also adopted a high-voltage pulse ignition device. Its advantage is that it can automate the gas ignition by using the self-control program and the flameout alarm system, which improves the reliability and safety of the ignition. However, in order to produce a reliable spark, attention should be paid to the arrangement of the voltage generator
