沸腾炉的爆管主要发生在埋管系统。埋管系统轻微爆管时,不易察觉,但有时会出现给煤量增大而炉温不易维持,风箱有水渗出,炉内有“刺、刺”声等。如果蒸汽压力较高,微小的漏口会很快扩大,造成大量的汽水冲向沸腾层,并很快汽化,炉内正压瞬时增大很多倍,高温的气体夹带着灼热的炉料 Boiling furnace tube burst occurs mainly in the buried pipe system. Buried pipe system slightly burst pipe, not easy to detect, but sometimes there will be increased coal and the furnace temperature is not easy to maintain, the bellows have water seepage, the furnace has “thorns, thorns,” and so on. If the steam pressure is high, the tiny leak will quickly expand, resulting in a large number of soft water rushed boiling layer, and soon vaporized, the instantaneous increase in pressure many times the furnace, high temperature gas entrained burning charge
