It has been decided to operate a steam power station on a Rankine Cycle with a relatively high condenser pressure of 8 bar so that the condenser cooling water can be used for a district heating scheme. The steam pressure and temperature at exit from the boiler are 100 bar and 500°C respectively. Neglect the power needed for the feed pump and assume the turbine operates isentropically. a) If 400 MW of power are required for the district heating, calculate the rate of steam required to flow through the condenser. b) What would be the net power (work rate) output from the plant?

Question
It has been decided to operate a steam power station on a Rankine Cycle with a relatively high condenser pressure of 8 bar so that the condenser cooling water can be used for a district heating scheme. The steam pressure and temperature at exit from the boiler are 100 bar and 500°C respectively.
Neglect the power needed for the feed pump and assume the turbine operates isentropically.
a) If 400 MW of power are required for the district heating, calculate the rate of steam required to flow through the condenser.
b) What would be the net power (work rate) output from the plant?
