Question 4 a. A factory requires electrical power for its machinery along with 80 MW of heat for process heating. The combined demand is achieved by using a superheated Rankine steam cycle in which the turbine is used to supply the electrical power required and the condenser cooling water provides the process heating to the factory. Steam is generated in a boiler at a pressure of 70 bar and it leaves the superheater at a temperature of 400°C. The steam expands through the turbine to a condenser pressure of 3 bar. The turbine isentropic efficiency is 0.85. The steam is condensed to saturated liquid in the condenser and a feed pump increases the condensate pressure to 70 bar for return to the boiler. The feed pump work may be neglected in the calculation. i. Sketch the cycle in a T-s diagram. ii. Calculate the steam mass flow rate required to satisfy the process heating demand. iii.
