Advantages and disadvantages of coal – the process

Electricity from coal is the electrical power produced from the energy kept in coal. Carbon dioxide, produced from historical vegetable materials, provides coal the majority of its power. This energy is released when coal is burnt.

We use coal-generated electrical energy for many different things, here are a few of them:





The whole process of transforming coal into electrical energy has several techniques and is identical to the procedure utilized to transform oil and gas into electrical energy:

A device termed as a pulverizer crushes the coal in to a fine dust.

The coal dust blends with very hot air, which will help the coal burn off more effectively, then the mixture moves to the furnace

The burning coal heats up normal water inside a central heating boiler, producing heavy steam.

Steam produced with the central heating boiler powers an engine known as a turbine, changing heating energy from burning coal into mechanized energy that rotates the turbine engine.

The rotating turbine is utilized to power an electrical generator, a piece of equipment that transforms mechanized energy into electrical energy. Such a thing happens when magnets inside of a copper coil within the generator rotates.

A condenser cools down the heavy steam shifting throughout the turbine. Since the heavy steam is condensed, it transforms back to normal water.

The water comes back to the central heating boiler, along with the cycle takes place once again

Electricity-generating facilities distribute electricity utilizing a transformer, which boosts the voltage on the electrical energy in accordance with the quantity necessary as well as the length it needs to travel. Voltages in many cases are as much as 500,000 volts at this stage.


Electrical energy streams alongside transmitting lines to substation transformers. These transformers lessen the voltage to be used in the local regions to become served.


In the substation transformers, electrical energy moves alongside distribution lines, which may be either below or above the floor, to towns and cities. Transformers yet again lessen the voltage—this time to about 120 to 140 volts—for risk-free use within houses and companies. The distribution procedure is instant. By the point you’ve flipped the switch to turn the light on, electrical energy has become provided.


advantages and disadvantages of coal

Natural gas and oil can also be utilized to make electrical energy. So how exactly does coal compare with the other non-renewable fuels? When it comes to supply, coal features a very clear advantage. The Usa has almost 300 billion tons of recoverable coal. That is sufficient to last about 300 years if we carry on using coal on the exact same rate as it’s used by us nowadays. Additionally, coal is really a flexible energy

. You can use it as being a stable fuel or it could be transformed into a gasoline to exchange pricey imported fuels.


But how about prices? The mining, transport, electrical energy generation, and pollution-control expenses associated with making use of coal are raising, but both natural gas and oil have become more costly to use as well. This really is, partly, simply because the usa need to import most of its oil supply from other nations around the world. It’s sufficient coal, nonetheless, to deal with its electrical energy requires, with plenty of remaining to foreign trade some coal too.


The price tag on making use of coal should continue being a lot more competing, in comparison with the increasing price of other energy sources. The fact is, producing electrical energy from coal is less expensive than the price of generating electrical energy from gas. In the usa, 23 of the 25 electrical power plants with all the cheapest managing prices are utilizing coal. Low-cost electrical energy, for instance that produced by coal, indicates reduced running expenses for home owners. This benefit can help boost coals competition in the current market.
