USA HISTORY

Detailed explanation-1: -geothermal power plant that uses heated underground water to warm a fluid with a lower boiling point than water, which creates a steam that powers turbines and electrical generators.

Detailed explanation-2: -Combustion. The source of heat for a boiler is combustion of any of several fuels, such as wood, coal, oil, or natural gas. Nuclear fission is also used as a heat source for generating steam. Heat recovery steam generators (HRSGs) use the heat rejected from other processes such as gas turbines.

Detailed explanation-3: -In steam turbines powered by fossil fuels (coal, petroleum, and natural gas), the fuel is burned in a furnace to heat water in a boiler to produce steam.

Detailed explanation-4: -A steam power plant consists of a boiler, steam turbine and generator, and other auxiliaries. The boiler generates steam at high pressure and high temperature. The steam turbine converts the heat energy of steam into mechanical energy. The generator then converts the mechanical energy into electric power.

Detailed explanation-5: -Steam power constitutes an important power source for industrial society. Water is heated to steam in power plants, and the pressurized steam drives turbines that produce electrical current.
