火电厂烟气脱硫系统中CEMS异常情况分析及改进

Abnormal situation analysis and improvement of CEMS in desulphurization system of coal-fired power plants

烟气连续监测系统(CEMS)是火力发电厂烟气脱硫系统中不可或缺的一部分,是烟气脱硫系统良好工作的重要保障。对烟气连续监测系统(CEMS)在烟气脱硫系统中设置的必要性及其能够实现的功能、工作过程进行介绍,并结合在实际火力发电厂运行中CEMS系统出现的典型、常见问题进行分析,得出发生原因以及相应的解决措施。

Continuous Emission Monitoring System（CEMS） is one of most important parts in desulphurization system of coal-fired power plants,and also guarantees desulphurization system in good working condition. This article introduces the functions and working process of continuous emission monitoring system,analyzes the problems of continuous emission monitoring system which operates in coal-fired power plants,and proposes the corresponding solutions combining with actual situation.
