稀释法CEMS在氨法脱硫的应用

Dilution Method of Gas CEMS Applied in Flue Gas by Ammonia Desulfurization

文章针对神华宁煤某电厂锅炉氨法脱硫后烟气湿度大,难以利用一般CEMS测量方法准确测量烟气成分的问题,根据稀释法CEMS测量特点,作者将该测量方法利用在氨法脱硫后烟气测量中,并对测量系统进行了详细设计。根据最终运行结果显示,稀释法CEMS测量适合氨法脱硫后烟气测量。

The article aiming at flue gas by ammonia desulphnrizatio of Shenhua Ningxia coal industry group boiler in one power plant is high humidity, It is difficult to use the general CEMS measurement method to measure the composition of flue gas accurately.According to the dilution method characteristics of gas CEMS, the author take it after flue gas by ammonia desulphur- ization, and has carried on the detailed design of measurement system.Then, the operation result shows dilution Method of Gas CEMS is fit for flue gas by ammonia desulfurization.
