what devices are used to generate coal

Clean Coal Technologies

The term 'clean coal' is increasingly being used for supercritical coal-fired plants without CCS, on the basis that CO 2 emissions are less than for older plants, but are still much greater than for nuclear or renewables. Some 27% of primary energy needs are met by coal and 38% of electricity is generated from coal.

Steam coal, also known as thermal coal, is used in power stations to generate electricity. Coal is first milled to a fine powder, which increases the surface area and allows it to burn more quickly. In these pulverised coal combustion (PCC) systems, the powdered coal is blown into the combustion chamber of a boiler where it is burnt at high temperature (see diagram).

How Do Thermoelectrics Work?

Heating one end of a thermoelectric material causes the electrons to move away from the hot end toward the cold end. When the electrons go from the hot side to the cold side this causes an electrical current, which the PowerPot harnesses to charge USB devices. The larger the temperature difference the more electrical current is produced and therefore more power generated.

How to Generate Electricity

Fossil fuels such as coal and oil is used to generate heat. This heat converts water into steam at very high temperature and high pressure. This steam at high pressure drives a steam turbine. The rotating shaft of the steam turbine is coupled to the armature of the alternator to generate electricity.

Coal

Coal is also used to produce very high temperatures through combustion. Efforts around the world to reduce the use of coal have led some regions to switch to natural gas and electricity from lower carbon sources. When coal is used for electricity generation, it is usually pulverized and then burned in a furnace with a boiler.

Resources used to make electricity

Fossil fuels, which include coal, oil and natural gas, are nonrenewable because it took millions of years for them to form. Once we use up our fossil fuels, they will be gone for good. Many power plants use fossil fuels. The fossil fuel is burned to produce heat, which is used to make steam. The steam is then used to turn the blades of a turbine.

How Is Coal Used Today?

Coal is primarily used in modern times to boil water and produce steam, which is in turn used to spin generator turbines for electricity generation. Nearly two-thirds of the coal recovered is now used in coal-fired power plants around the world. Coal is also used in the steel manufacturing process, which utilizes coke, a by-product of burning coal.
