摘要
以国产引进型600 MW机组为例,研究了滑压运行方式下开启不同数目的调节阀对机组性能产生的影响,包括调节级相对效率、调节级有效比焓降、高压缸效率、给水泵耗功等;并从上述比较中得出了机组的最佳滑压运行方式,指出对于不同型式的机组,应该开启不同数目调节阀,以提高机组的运行经济性。
Taking the licensed 600 MW power unit as an example,influence of opening different number of control valves on the unit performance is being analyzed,such as on the relative efficiency and efficient specific enthalpy drop of governing stage,the efficiency of high pressure cylinder,the power consumption of feed pump etc.Optimal mode for sliding pressure operation is obtained from above comparison.It is pointed out that for different types of power unit,different number of control valves should be open so as ...
