A power station consists of a four-unit coal fired power station, having a combined capacity of 2,880 MW. The current efficiency of each unit is around 37.7%. You are asked to improve the thermal efficiency of each unit by lowering the condenser pressure. To simplify this task, assume that each unit operates on a simple ideal Rankine cycle. If the superheated vapour enters the turbine at 10 MPa and 500 ֯C and is cooled in the condenser at a lower pressure 10 kPa, determine the quality of the steam at the turbine exit and the thermal efficiency of the cycle for one unit.
