The steam generator provides 4.0x104 kg/h of steam at 10.0 MPa, 470°C, of which 30% is extracted between the first and second turbine stages at 1.2 MPa and diverted to a process heating load. Condensate returns from the process heating load with a 4% pressure loss at 140°C and is mixed with liquid exiting the lower-pressure pump at the same pressure. The entire flow is then pumped to the steam generator pressure. Saturated liquid at 10 kPa leaves the condenser. The turbine stages and the pumps operate with isentropic efficiencies of 82 and 80%, respectively.
