摘要
聊城电厂600MW机组投产以来一直存在调节阀无法切顺序阀运行问题,对机组的效率影响较大。经过理论分析和强度校核,确定将原顺序阀方式改为对角开启顺序阀方式并结合试验情况对重叠度进行优化,改进后运行效果良好,经济效益显著,在同类机组中具有较高的推广应用价值。
Liaocheng power plantb 600MW unit cant perform the switching operation from governing valve mode to sequence valve mode, which has long been a problem and affected the unit efficiency apparently. An improving method of opposite angle opening and degree of overlapping optimization＇is proposed by theoretic analysis and strength check, which has achieved a good operation effect and distinct economic benefits after application, as well as high popularization value for applying to other units of the same kind.
