摘　　要：加强机组启停过程管理,关注受热面氧化皮生成速率,结合机组启动初期,使用PCV阀吹扫氧化皮等预防方式,积极进行探索,做好机组停运期间的防磨防爆检查工作,防患于未然。应对电网负荷调度及机组顶尖峰等影响,克服机组负荷存在频繁快升快降变化导致的锅炉受热面爆管等问题。Strengthen t he crew start-stop process control,pay attention to the rate of oxygenation of the skin on the heating surface.Initial start-up of the unit.Use the PCV'valve to purge the oxygenated skin and other precautionary methods.Actively explore.Do a good job of anti-wear and explosion-proof inspection during the shutdown period of the unit.Prevention is better than prevention.Should be affected by the load regulation of the grid and the peak of the unit peak,etc..The load of the server unit is frequent,rising and falling rapidly,and the heating surface of the boiler is bursting.
