摘要

针对给水加氧处理是否影响过热器和再热器氧化皮的脱落这一争议问题

本文依据实验室试验数据、现场调研结果

对多个争论的焦点问题进行分析。结果表明

过热蒸汽中的氧与钢发生反应

产生的Fe_2O_3能够促进奥氏体钢氧化皮的集中脱落

所以给水加氧处理是影响过热器和再热器氧化皮脱落的因素之一。

Abstract

The discussions on whether oxygenated treatment influences the exfoliation of oxide scale from superheater and reheater tubes have been lasted for more than ten years.Based on analysis of the experimental data and investigations on field application

several hot debates are analyzed in this paper.The research indicates that the oxygen in superheated steam can react with steel

and the reaction product Fe_2O_3 can promote the exfoliation of oxide scale from the austenitic steel

and the oxygenated treatment is one of the factors influencing the exfoliation of oxide scale from the superheater and reheater tubes.
