Steam turbine plant internal power PST-60 MW, Qond97 MW, Q-65 MW, organic efficiency n.=0.95, heat recovery steam
generator. T,-423.15K
Gas turbine plant compressor p, = 1 bar, T, = 293 K, B,-10, polytropic exponent m=1.473; turbine: polytropic exponent
m=1.279, T,=1325.15K, burner. n=0.97,n=0.97, fuel. H-42500 kJ/kg,
Fluids air (k = 1.4, R= 287 J/kgK, c = 1004.5J/kgK), burned gas (k' = 1.335, R'=293 J/kgK, c=1168 J/kgK)
