模拟计算在锅炉运行分析中的应用

Application of simulation calculation in the operation analysis of boiler

电站锅炉在运行中会发生各种问题。如何应用现场测点提供的数据,通过有效计算方法,定量分析并解决锅炉运行中存在的问题,是电站研究人员追求的目标。为此提出一种运用现场测点提供的数据,模拟锅炉实际运行情况的锅炉热力计算方法。应用该方法对金陵石化热电厂220t/h锅炉进行计算和分析,找出了导致锅炉排烟温度升高、过热器超温的原因。此外,模拟计算结果还有助于电站研究人员分析其它锅炉运行问题。

Various problems may occur in the operation of utility boilers.By using the data provided by on-site measure points,through the effective calculation method,to quantitatively analyze and solve the exiting problems in the boiler operation are the tar-gets which utility researchers follow after.For this reason,the thermodynamic calculation method,by using the data provided by on-site measure points to simulate the actual operation by on-site measure points to simulate the actual operation conditions of boiler,was put forward.By using this method,the operation of220t/h boiler in Jinling Petrochemical Cogeneration Power Plant was calcu-lated and analyzed,and the causes leading to the rising of boiler exhaust gas temperature and overheating of superheater were found out .Besides,the simulation calculation results help utility researchers analyze the other operation problems of boilers.
