摘　　要：随着国内一大批80年代投产的火电机组陆续达到或已超过设计寿命,如何科学、全面地评估这些到期与超期服役机组重要部件的安全性与剩余寿命已成为当务之急,关系到大批老机组在今后10～15年内能否安全运行。对此,介绍了国内外最新的剩余寿命评估技术,并提出一种全面评估老机组安全性与剩余寿命的方法,包括评估范围、评估步骤及程序以及剩余寿命评估方法。As a large number of domestic thermal power units put into operation in the 1980s had reached or exceeded their design life, it was urgent to evaluate scientifically and comprehensively the safety and remaining life of the important parts of these units that had become a priority. It related to the safety of these old units in the next 10 to 15 years whether safe operation. As a result, the latest technology of residual life evaluation domestic and abroad was introduced. A comprehensive method to evaluate the safety and residual life of the old unit is proposed, including evaluation scope, evaluation procedure and residual life evaluation method.
