How is electricity generated in power stations that burn coal oil?

Coal Oil, Oil, Coal... fossil fuels are burned to provide the heat necessary to boil water. the boiling steam is pressurized (due to the nature of gases are less dense than water) and is forced through some piping to the turbine, basically the reverse of a jet engine. It lowers the pressure and temperature out of the air by taking work out of it and generating electricity.





You can find all this out on wikipedia by searching power generation and other related termsHow is electricity generated in power stations that burn coal oil?
The oil is burned to create heat and the heat creates steam which turns a turbine which turns a generator which creats the electricity. The steam is important because it has a large expansion rate and you get more power for the expensive heat.How is electricity generated in power stations that burn coal oil?
Assuming you meand ';coal or oil.'; The fuel is burned to heat water to produce steam, and the steam is used to propel a turbine and generator to produce electricity. The waste steam is condensed back into water and recirculated through the system.





There are large amounts of information about this process available easily on the Internet. Just run a search on ';electric power generation.';
The coal is burned in large furnaces. Inside these furnaces are pipes filled with water. The pipes and water wind back and forth until the water boils off and turns in to steam. The steam then leaves the boiler and heads to a turbine. The energy in the steam turns the blades of the turbine, much like air turning a fan blade.





As the turbine blades spin, it causes rotors and stators (magnets and coiled steel) to produce electricity through magnetism. The cooled steam can then be used to improve the efficiency of the power plant by running through lesser pressure turbines or it can be returned to the boiler where the coal again heats the water to steam.
