摘要
介绍了浙江国华宁海电厂4号机组锅炉炉水由磷酸盐处理改为氢氧化钠处理的试验和运行情况。结果表明,炉水采用氢氧化钠处理方式后,含盐量明显降低,炉水品质得到改善,从而使蒸汽钠含量明显降低,减少了过热器和汽轮机的积盐风险,对电厂的节能降耗具有重要意义。
This paper introduces the test and operation situation of replacing phosphate treatment with sodium hydroxide treatment for Unit 4 boiler water in Zhejiang Guohua Ninghai Power Plant. The result shows that the salinity of boiler water declined after sodium hydroxide treatment and the boiler water quality was improved so that it lowered the sodium content of vapor and reduced the salification risk in the superheater and steam turbine. It is of high significance for energy saving and consumption reduction in power plants.
