vapour power cycle

It is a cycle in which heat energy is continuosly converted into shaft work. The working fluid used in it is water and it undergoes a phase change during the whole process. Vapour power cycle mainly consists of four parts. They are following:-
1) boiler
2) turbine
3) condenser
4) pump
water is heated into boiler with the help of external source i.e. furnace to make it steam. This high pressure , high temperature steam expand in the turbine to produce shaft work. As heat energy is converted into shaft work steam comes back in water form which is then condence in condenser where it rejects heat. Then water is pumped back to boiler and in this fashion cycle repeat and shaft work is produced.
