摘　　要：汽包的运行监测及管理在火电机组运行管理中占有重要一席,其运行的合理性直接影响到机组安全、经济运行.因此,加强对汽包壁温差的监测,合理控制汽包壁温差是极其重要的.目前,一些国产锅炉汽包存在运行监测手段不完善,运行管理方法不合理,有的工况壁温差无法控制在规程规定的范围之内等问题.本文就汽包的运行监测、壁温差的控制、壁温差对寿命的影响问题作一初步探讨.Supervision and control of drum metal temperature of utility boilers are very importamt to safety and economical operation of the units. For some domestic boilers, the on-line supervision of drum metal temperature has to be perfected and operation management has to be rationalijed. In Some operation conditions, drum metal temperature even cannot be controled within specified allowable range. The article deals with on-line supervision and control of boiler drum metal temperature and its effect on boiler life.
