超临界锅炉受热面氧化皮问题的研究

Study of the Scale Problem of Supercritical Unit heat surface

本文介绍超临界机组受热面氧化皮的产生机理,主要是受热面使用的奥氏体不锈钢材料在长期高温运行,在温度变化时产生剥离。介绍了氧化皮对机组运行产生的危害。本文给出了一些措施来控制超临界机组受热面氧化皮的产生。

This paper introduces generation mechanical of supereritical Unit heat surface. When austenitic stainless steel of heat surface run in high - temperature for a long time , Peeling generated during temperature changes. It described the damage to the Unit . It also gives several measures to control scale.
