Steam 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.

Sodium Monitoring TECHNICAL NOTE On Power Plant

steam 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.

2.3 Boiler and steam cycle model. In the steam cycle shown in Figure 1, the pressure of the feed water increases to 2 atm by Pump 1. 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.
