摘要
介绍了发电厂汽轮机组配汽方式及各种方式的优缺点,对喷嘴配汽汽轮机调节级室温度变化带来的影响进行了分析。为了使调节级室的压力、焓值、温度以及调节级效率等参数满足变工况计算需要,在常规的调节级变工况计算中增加了温度的迭代计算,以求得更精确的调节级参数。
The principle of steam governing arrangement of steam turbine in power plant is discussed in this paper which involves the advantages and disadvantages of various ways. Then, the analysis on influential circumstances arising from the temperature variation of governing-level chamber was also made. To meet the needs of the oft^design condition amongst the pressure, enthalpy, temperature ＆ governing stage efficiency, etc, a supplementary iteration of temperature on the normal off-design calculation on the governing stage were tackled. Accordingly, more refined parameters of the governing stage were deserved.
