摘要
利用火力发电厂烟气排放连续监测系统(CEMS),实现锅炉烟气中一氧化碳(CO)、氧气(O_(2))的测量,设计完善风量氧量串级控制系统,实现CO-O_(2)联合控制。实际应用结果表明:该系统投入后可以有效监控CO含量,减少锅炉燃烧中产生的CO,为锅炉燃烧调整提供数据支持,提高锅炉效率,减少水冷壁高温腐蚀,进而提高锅炉运行的安全性、经济性。
For a thermal power plant,the continuous emission monitoring system(CEMS)was adopted to realize the measurement of carbon monoxide(CO)and oxygen(O_(2))in boiler flue gas,and the air-oxygen cascade control system was designed and optimized to realize the combined control of CO and O_(2).Actual application results show that this system can effectively monitor the CO content and reduce CO generated in boiler combustion.Through providing data for the boiler combustion adjustment,this system can improve the boiler efficiency,alleviate the the high temperature corrosion in boiler water wall,and improve the safety and economy of boiler operation.
