Also known as ‘steam coal’, thermal coal is the primary variety of coal used in boilers to generate steam to produce power. It is commonly used in power plants and kiln fuels for the production of cement.
Anthracite is another variety of coal that’s almost entirely comprised of carbon (90% to 98%), making it the hardest form of coal. Anthracite is difficult to ignite, but is known for being the cleanest burning form of coal as it gives off the least amount of pollutants. It’s ability to provide ‘clean’ energy makes it a good option for organisations looking for a more eco-friendly power generation option. Anthracite is used for domestic furnaces as well as in steam-powered generators. It can also be liquified to be utilised in internal combustion engines.
Petroleum coke, also known as ‘petcoke’ is a byproduct of the oil refining process. After fuel products and lubricating oils have been processed from crude oil, the excess is superheated through a process called ‘coking’. This produces a stable, carbonaceous solid fuel that is often used in coal-fired power plants and cement kilns.
