摘要:

火电厂脱硫区域烟道与主机烟道直接相连,超低排放改造后,脱硫烟气温度更低,腐蚀性更强,改造后脱硫系统的安全、稳定运行成为研究重点。以华电漯河发电有限公司为例,分析了纯钛烟道膨胀节在脱硫系统应用的可行性,并在脱硫区域改造中成功应用,供同类机组参考。

Abstract:

Thermal power plant desulphurization flue gas duct usually connected to boiler flue gas duct. After ultralow emission reconstruction, temperature of desulphurized flue gas is low and has stronger corrosivity. Take the example of Huadian Luohe Power Generation Company Limited, the feasibility of applying pure titanium flue gas duct expansion joint was analyzed. This reconstruction was implemented. Which could be referred by similar unit.
