采用湿法脱硫后的钢烟囱防腐施工处理

Anti-corrosion Treatment of Steel Chimney after Implementing Wet Flue Gas Desulfurization

火电厂采用湿法脱硫后,钢烟囱的腐蚀情况较为严重。通过对一起严重的钢烟囱腐蚀泄漏问题进行分析,制定了技术改造的方案和措施,严格保证施工各环节的质量,经过两年半运行的考验,取得了预期的效果,可为其他电厂钢烟囱防腐提供参考和借鉴。

The corrosion of the steel chimney is a serious problem in thermal power plant after implementing wet flue gas desulfurization. The technical reform scheme and measures that guarantee the construction quality of each link are created, and the desired results have been obtained for a two and a half year of operation after implementing the scheme.
