Turbine (HP) Re-heat Turbine (LP) PH P1 Diagram 1H A co-generating Rankine cycle is shown in Diagram 1H. The cycle works with a boiler pressure of 4MP2 and a condenser pressure of 18kPa. The process heater works at 2MPA, and the re-heater works at 800kPa. Steam leaves the boiler at 400°C, the re-heater at 500°C and the condenser at 55°C.

Diagram 1H
A co-generating Rankine cycle is shown in Diagram 1H.
The cycle works with a boiler pressure of 4MP and a condenser pressure of 18kPa. The process heater works at
2MPA, and the re-heater works at 800kPa. Steam leaves the boiler at 400°C, the re-heater at 500°C and the
condenser at 55°C. Losses due to friction in the turbine is 8%.
39% of the heat removed in the condenser is used for heating.
Do your calculations per kg of steam flowing though the cycle, 15% of the steam is used for process heating.
