摘要

燃煤火力发电站利用高温高压蒸汽为工质进行发电。随着火力发电的水蒸汽参数提高到超超临界

水蒸汽氧化问题变得尤其突出。当前超(超)临界火电站锅炉用耐热钢主要有低合金耐热钢、9%Cr型马氏体耐热钢和18Cr-8Ni型奥氏体耐热钢。综述了上述三类耐热钢的蒸汽氧化行为

着重介绍了动力学规律和氧化皮结构特点以及提高抗蒸汽氧化性能的方法。并对这三类材料使用中会出现的蒸汽氧化问题提出了对策。

Abstract

Coal fired power plants use high temperature and high pressure steam to make electricity. With the steam parameter improved to ultra-super critical

the steam oxidation becomes much more serious. Heat resistant steels for coal- fired power plants mainly include low alloy heat resistant steels

9% Cr martensitic heat resistant steels and 18Cr-8Ni austenitic heat resistant steels. In this paper

the steam-oxidation behavior of the three kinds of heat-resistant steels is reviewed

and the kinetics and the structure characteristics of the oxide scale are introduced. The methods of improving steam oxidation resistance are summarized. The methods for avoiding possible oxidation problems in service exposure of the three kinds of materials are suggested
