Question:
The power plant has a net power output of 80 MW running on a renewable steam energy cycle with four feed water heaters, three closed and one open, and heats up. Steam enters the turbine at 15,000 kPa, 600 °C, expands in three stages in the high pressure turbine and then expands in three more stages to the condenser pressure of 10 kPa. The saturated liquid exits the condenser at 10 kPa. Between the first and second stages, some steam is transferred to a closed feed heater at 8000 kPa. between
The second and third stages, the additional steam is transferred to a second closed water heater at 4000 kPa. Steam is extracted between the fourth and fifth stages of the turbine at 800 kPa and fed into an open feed water heater operating at this pressure. The liquid saturated at 800 kPa leaves the open feed water heater. Between the fifth and sixth stages, some steam is transferred to a feeder heater closed at 200 kPa. The condenser leaves each closed closed water heater as a saturated liquid at the respective extraction pressures. (9 marks) (a) Show the course on the Ts diagram.
