据不完全统计,在用工业锅炉事故发生率较高的是爆管事故或炉管渗漏占其事故发生总数约70%。此类事故除部分属水循环故障外。多数是腐蚀所致。据笔者多年检验锅炉的经验,一般工业锅炉投用3~5年即发生炉管渗漏(水冷壁管、对流管束、省煤器管等)不在少数,而投用6~8年则是普遍现象,需换管大修。随着城市集中供热的趋势化、普遍化,锅炉单机容量越来越大,一旦发生事故被迫停
According to incomplete statistics, the higher incidence of accidents in industrial boilers is that burst pipe accidents or furnace pipe leakage account for about 70% of the total number of accidents. In addition to some of these accidents are water cycle failure. Most are caused by corrosion. According to the author many years of experience in testing the boiler, the general industrial boiler cast tube leakage occurs 3 to 5 years (water wall tube, convection tube bundle, economizer tube, etc.) is not a minority, and cast 6 to 8 years is common Phenomenon, need to change pipe overhaul. With the trend of urban central heating, universal, single boiler capacity is increasing, in case of an accident was forced to stop
