摘　　要：电站锅炉"四管"爆漏事故是造成电厂非计划停炉的主要原因,而超温过热、腐蚀、磨损、热疲劳等是造成锅炉"四管"爆漏的主要原因。分析了引起超温过热、腐蚀、磨损、热疲劳等的具体原因,以期对锅炉"四管"爆漏问题的处理提供依据。The burst- leakage of ＂four tube kinds＂ in utility boilers are main causes leading to non -planned boiler shutdown in power plants,while the main causes resulting in burst- leakage of ＂four tube kinds＂ in boilers are.. overtemperature excess heating, corro- sion, worn - out, and thermal fatigue etc.. The concrete causes leading to over temperature excess heating, corrosion, worn - out, and thermal fatigue etc. have been analysed, so as to provide basis for elimination of the burst- leakage problem for ＂four tube kinds＂ in boilers.
