摘　　要：在燃煤电厂烟气脱硫技术改造项目中,因不设烟气换热器而需要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,需要设置临时烟囱。以华电白音华金山发电有限公司技术改造工程为实例,介绍了组合式临时烟囱的设计方法,该方法为烟囱防腐改造提供了一种新思路。In FGD technical reformation project of coal-fired power plant,the gas-gas heater is eliminated,and the original chimney must be reformed for anticorrosion. So a temporary chimney is necessary to ensure the main machine to operate normally during the chimney anticorrosion reformation. Taking the technical reformation project of Huadian Baiyinhua Jinshan Power Generation Company Limited as example,a design method of combined type temporary chimney was introduced. The method of this paper provides a new idea for chimney anticorrosion reformation.
