Boiler Efficiency and Steam Quality: The Challenge of

Boiler efficiency measures how much combustion energy is converted into steam energy, while steam quality measures how much liquid water is present in the steam produced. A major benefit of using steam as a heat transfer medium is the large amount of heat released when it condenses into water.

Marine Steam Boiler Water Test Procedures,

Superheated steam from the boiler is fed into the steam turbine where it expands through the different stages before exiting into the main condenser. This converts any remaining steam to condensate which is fed through the deaerator, and several heaters before being pumped under high pressure back into to the boiler via the main boiler feed valve.

Pressure Steam - an overview | ScienceDirect Topics

The advances in steam pressure and temperature led to the development of the reheat cycle, where steam is exhausted from the high-pressure turbine at reduced pressure and temperature and is then returned either to a section of the boiler or to a separate boiler to be reheated. Once reheated, the steam is sent to the low-pressure boiler.
