Boiler (power generation) - Wikipedia

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (72,000 kPa or 1290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

Boiler - Energy Education

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.All but a small fraction of the world's primary energy comes from fuels, and about three-quarters of
