Optimization of Process of Start-up and Shutdown for Peak Modulation Steam Boiler

基于降低疲劳寿命损耗和缩短启动时间 ,建立优化模型 。

A optimal model is developed to reduce the range of fluctuation stress in pressure vessel and cut down the time consumed in the start up and shutdown process,by setting the time interval of each pressure variation stage as optimal variable.The reasonable result is obtained in numerical example.The method proposed here can be applied in the efficient control of fatigue life for peak modulation steam boiler .
