How do power plants work? | How do we make electricity?
Types of power plants Steam turbine. Most traditional power plants make energy by burning fuel to release heat.For that reason, they're called thermal (heat-based) power plants. Coal and oil plants work much as I've shown in the artwork above, burning fuel with oxygen to release heat energy, which boils water and drives a steam turbine.This basic design is sometimes called a simple cycle.

Power plant - Energy Education
The power plants require the use of nuclear reactors to carry out these fission processes. Some types of reactors include pressurized water reactors, CANDU reactors, RBMK reactors, and boiling water reactors. Solar thermal power plants use heat from the sun's rays to create the steam that is needed to rotate the turbine.

Coal-Fired Thermal Power Plant - an overview ...
Coal is the dominating fuel source used in thermal power plants for generation of electricity. At the coal-fired thermal power plants, the raw coal is first pulverized to the shape of flour before it is force-fed to the furnace. During the pulverization process, the clay particles entrapped in the cracks of coal get separated from the coal.

Geothermal Power Plant Working Principle - your electrical ...
Geothermal Power Plant Working Principle. Normally the thermal energy available inside the earth is at a depth of more than 80 km. The average temperature gradient in the earth's surface is 30 o C /km depth. Therefore, for power generation to attain temperatures up to 300 o C, a hole has to be drilled in earth's surface of about 10 km depth.

How Geothermal Energy Works | Union of Concerned Scientists
The plants at the Geysers use an evaporative water-cooling process to create a vacuum that pulls the steam through the turbine, producing power more efficiently. But this process loses 60 to 80 percent of the steam to the air, without re-injecting it underground. While the steam pressure may be declining, the rocks underground are still hot.
