给水加氧处理技术在超临界直接空冷机组中的应用

摘要

介绍超临界机组加氧目的、原理和特点，以神华河北国华定洲发电有限责任公司3号、4号机组为例，分析超临界直接空冷机组给水加氧处理技术的应用情况，并从锅炉压差变化、铁含量变化和空冷岛转化三方面说明应用效果。%This paper describes purpose,principles and char-acteristics of the oxygen adding treatment for the supercriti-cal unit.Taking the 3rd and the 4th unit of Shenhua Hebei Guohua Dingzhou Power Company Limited as an example, the paper analyzes the application of feed water oxygen adding treatment technology for supercritical direct air cool-ing unit,and illustrates the application effect from three as-pects such as boiler pressure difference change,iron content change and air cooling island conversion.
