Question
5) Analyse a cogeneration Rankine cycle with the following conditions:
Heat input to the cycle: 20 MW
• Inlet conditions to the turbine: 3.0 MPa, 350 °C
• Intermediate steam conditions (for the process): 1.0 MPa, 50 % of the mass flow
• Condenser saturation temperature: 40 °C
Isentropic efficiency of the pumps and turbine: 75 %
Clearly state any assumptions.
