Fig. 1. Effect of single operating parameters
time. As shown in Fig. 2(a), the higher cycle efficiency can be obtained by combining
higher steam generator pressure with lower condenser pressure, which is obvious. As
shown in Fig. 2(b), higher Rankine cycle efficiency can be obtained by combining the
equipment efficiency of higher pump and steam turbine. However, the effect of pump
equipment efficiency on system efficiency is relatively small, and the operating efficiency
of existing equipment is close to 1.
