How is electrical energy produced at power plants?

Answer 1

There are many sources of power available to power company. hydro water thermal natural gas and of course oil. not to forget nuclear water as it flow down that energy can be used to generate power by spinning a turbo propeller. natural gas can be used to generate steam and its energy can be used of course oil burning will heat water too. nuclear by generating heat will do the same process heat water.

Answer 2

Using fossil fuel, such as coal, oil, or natural gas, water is evaporated to steam and superheated to a high temperature and pressure. This is then fed to a steam turbine which is connected to a generator, the whole unit spinning at high speed and producing electricity, which is then exported via Transformers which step up the volts to a high level (maybe 400,000 volts) for efficient transmission to the load center.

A nuclear reactor if used simply replaces the fossil fired boiler, the rest of the chain is similar.

Answer 3

Method 1. By passing steam through a turbine which drives a generator. The steam is generated by super heating water by burning fossil fuels or nuclear reaction. Method 2. By releasing water from a reservoir to drive turbines. Method 3. By harnessing the power of the wind or waves to drive generators, or the power of the sun to either pre-heat water to make steam production, to drive turbines, cheaper, or to charge batteries for conversion to grid power. Method 4. Modern power plants burn gas to power turbines (like jet engines) and then, rather than waste the exhaust heat generated, they re-use it to make steam to assist in driving more turbines. A comparatively efficient system.

Answer 4

Huge generators turn magnets inside loops of wire. The resulting changes in the magnetic field relative to the coils induces an electrical current in the wire. The generators themselves are rotated by water- or steam- driven turbines.

Answer 5

Power plants burn a fuel to create heat. The heat is used to produce a super heated steam, which rotate a turbine. The turbine is hooked up to a generator which generates electricity.

This is generally how power plants work. In the case of nuclear, nuclear fission is used to create the heat.

Answer 6

large dams are constrycted to control the release of water. As water passes through machinery in the dam, turbines move and produce electricity................:-)
