superheating the steam in the boiler and condensing it completely in the condenser. This cycle that results is the Rankine cycle, which is the ideal cycle for vapor power plants. The construct of power plant and T-s diagram is shown in Figures 2.2(a) and (b). (a)
Read moreSteam is the working substance used for the propulsion of many surface ships, including nuclear and conventionally powered steam ships. Central to understanding the operation of steam propulsion is the basic steam cycle, a process in which we generate steam in a boiler, expand the steam through a turbine to extract work, condense the steam into water, and finally feed the water back to the boiler.
Read moresteam cycle and the water treatment plant on modern power stations, is now a very well established practice. This enables careful control of the water chemistry to achieve peak efficiency and minimise downtime due to excessive boiler corrosion or scaling.

The feed water entering the deaerator is further preheated to 127 °C by the steam at 159 °C and 6 atm coming from the turbine extraction valve. The pressure of the preheated feed water rises to 67 atm by Pump 2.
