Abstract
The method of choose of optimal pressure of intermediate overheating of vapor at steam-turbine plants (STP) cycle is proposed. For this aim values of thermal coefficient of efficiency of STP cycle at several values of intermediate overheating pressure are calculated. The results of calculations of thermal coefficient of efficiency at initial pressures 6, 8 and 10 MPa and condensation pressure 0,005 MPa are presented. The analysis of these results showed, that optimal values of intermediate overheating pressure are 1,2, 1,5 and 2,4 MPa correspondingly.
