汽轮机变工况时各监视段压力与温度的定量计算

Monitored Section Pressure and Temperature Quantitative Calculation of Steam Turbine Off-design Condition

汽轮机各监视段压力与温度是计算机组运行经济性必不可少的条件,同时又是监视汽轮机运行中通流部分是否完好的重要依据。根据汽轮机变工况的原理以及弗留格尔公式,提出一种对汽轮机监视段压力与温度计算的新方法,并结合实例进行计算。研究成果为机组的安全经济运行提供了有力的保障,为在线计算机组的运行经济性提供了方便。

The monitored section pressure and temperature of steam turbine is essential condition to calculate operation economics of unit, and it is also important basis to monitor whether the flow passage of steam turbine operation is good. A new calculation method of the monitored section pressure and temperature is proposed based on steam turbine off-design condition principle and flugel formula, and a calculation example is given . By the research results, a powerful support to safe and economical operation of unit is offered, and a convenience for operation economics of unit on-line calculation is provided.
