超超临界锅炉氧化皮的防治

Oxide-layers' s Prevention of Ultra-supercritical boilers

随着发电机组容量越来越大,超超临界机组不断引入,新材料也不断应用其中,在锅炉四管中存在金属氧化皮的生成,造成爆管,机组停运事故,通过对氧化皮产生根源进行分析,提出防治方法。

With the generator set capacity is growing, and uhra-supercritical units is Constantly intro- dueing , but also the continuous application of new materials in which scale formation in the presence of four pipes in the boiler, resulting in pipes bursting, unit outage accident, through the analysis of the root causes of the oxide-layers, it proposed control methods
