How does a thermal power plant work?

Thermal power plant uses heat source like burning coil, gas, wood or natural heat sources like solar heat or geysirs. Heat is transformed to vaporising water. When water turns into steam it has lot of energy(entalphy) in it. this energy is used in wanted application as turbine or central heating. Most of the energy is where the steam turns back to water. Thermal power plant usually has both electric turbine and distributional heating because of better use of energy. Electric power production pays more and some applications are made only for electric production.
