摘要: 在燃煤电厂烟气脱硫(FGD)技改项目中,因不设烟气换热器而需对原烟囱进行防腐改造。为了解决因施工影响主机运行的难题,需设置临时过度烟囱。结合工程实际情况,介绍了设置临时烟囱的2种方法,该方法可为类似技改工程提供参考。

Abstract: In retrofitting project of wet FGD for coalfired power plants, the original stack need to be upgraded for corrosion resistance due to that the GGH will be eliminated. In order to avoid its influence to the operation of main units, it is necessary to construct a temporary stack. In this article, two methods for construction of temporary stack widely used in actual projects were introduced, and the methods can also be used as good reference for similar project.
Key words: wet flue-gas desulphurization, technical reformation project, gas-gas heater (GGH), stack anticorrosion, temporary stack
