Quickly absorbs heat from water
It is a device that heats the steam generated by the boiler again, increasing its thermal energy and decreasing the chances that it will condense inside the turbine
Superheater
These are energy sources which are not destroyed when their energy is harnessed.
Renewable energy
It is a heat exchanger which utilizes the heat of the flue gases to preheat the air needed for combustion.
Preheater

Diversity Factor
The ratio of average load to peak load over a designated period of time is called:
Load Factor
The difference between the temperature leaving the unit and the temperature of the feedwater entering.
Terminal Difference
A contact heater that is especially designed to remove the non-condensable gases.
Deaerator
