- Indicate TS- Diagram and Use SI unit Steam Table In a steam power plant that uses reheat cycle steam at 15.5 MPa, 545 °C enters the engine and expands to 1.95 MPa. At this point the steam is withdrawn and passes through a reheater. It reenters the engine at 535 °C. Expansions now occur to the condenser pressure of 0.0035 MPa. Find the efficiency in %.Н.W A smaller power plant produces steam at 3 MPa, 600•C, in the boiler. It keeps the condenser at 45 C by the transfer of 10MW out as heat transfer.
