燃烧优化系统在600MW机组锅炉控制中的应用
摘要
利用锅炉运行数据和机组DCS
通过建模及优化实现了锅炉燃烧优化的闭环控制。在通辽发电总厂600MW机组上的应用结果表明
在600 MW负荷下
锅炉燃烧优化控制系统可使锅炉热效率提高0.58%
氮氧化物排放浓度降低10%以上。
Abstract
By using data in boiler operation and the existing DCS control system
through establishment of model
the closed-loop optimization control in boiler operation has been realized.The result of application on 600 MW unit in Tongliao Ceneral Power Plant shows that as in the following:under load of 600 MW
the thermal efficiency of boiler has increased 0.56%
the concentration of NOx emission has decreased more than 10%.
