Question
1. A medium size power station is used to produce 30 MW net power for a refinery. The station uses
steam as the operating fluid and operates according to the Carnot cycle between the pressure
limits of 0.4 bar and 35 bar. Steam enters the boiler as a saturated liquid and leaves it as a dry
saturated vapour.
(i)
List the name of the four processes in a generic Carnot cycle and state what type of energy transfer
(work/heat) can be neglected in each process.
(ii)
Sketch a T-s diagram for the above cycle indicating the location of the four components required.
(iii)
Determine the dryness fraction of the steam that is fed to the condenser.
