摘　　要：某电厂^#1～^#4锅炉为引进CE型燃用贫煤早期产品，首台机组于1991年投产，由于超温、磨损、裂纹等原因，导致锅炉再热器爆管较多。结合4台锅炉十几年来的常见再热器爆管的处理情况，进行了综合分析，为防止和减少再热器爆管问题提供了一个实例，对同类型锅炉有借鉴意义。No. 1 - No. 4 lean coal-fired boilers in some power plant were early products manufactured using introduced technique from CE. The first unit was put into operation in 1991, the faults of boiler reheater pipes cracking were occurred many times because of over-temperature, wear and crack. Combining with these 4 boilers＇ treatment experiences, the comprehensive analyses have been done for the common pipe cracking faults of boiler reheater. An example was presented in this paper as a reference for the same type of boilers.
