摘要
对回热系统主要监测参数的运行基准值进行在线计算,主要针对变工况下加热器的端差、抽汽压损的基准值定量计算,对过热器减温水量的基准值的在线计算模型进行了分析,并籍此对某电厂300MW汽轮机组进行了计算分析。回热系统运行基准值对于指导运行,在线分析及故障诊断有一定的现实意义。
This paper gives a online-calculation on the operating standard value of the main monitor parameters of thermodynamic system and lays emphasis on the difference from heater and the press loss of the extract steam pipe. The computing model of the spray desuperheating is put forward. On the base of them, a 300 MW-turbine set of a power plant is being studied and calculated. There is some significance of the standard value of the thermodynamic system for guiding operating, online analyzing and the monitoring fault.
