Boiler
Thermal power is supplied by a fuel to a boiler. [1] Boilers are used in power plants in order to produce high pressured steam, so that the plant can generate electricity. The process that does this is known as the Rankine cycle. The boiler takes in energy from some form of fuel such as coal, natural gas, or nuclear fuel to heat water into steam.

Boiler storage best practice
Wet storage is generally employed when boilers will be idle for brief periods and/or may require start-up with short notice. Chemicals are added to deaerated boiler feedwater in the boiler to protect metal surfaces from both oxygen and low pH attack. Chemical residuals are maintained at higher-than-normal levels to ensure maximum protection.
