Anthracite:
Anthracite coal is the highest quality of solid fossil fuels. It consists of 95% carbon and the water rate is low. It is the hardest type of coal and gives off more heat when burned than others. It is found in very small amounts in nature and is therefore difficult to find. It is brightly colored and difficult to ignite.
Lignite:
It is soft, easily crumbled, brittle and dull in appearance. Lignite coal, which has a low carbon content, contains very high moisture. Lignite coal is largely used for electricity generation in our country and in the world.
Coal:
Its calorific value is one of the highest quality coals. In hard coal, carbonization is at a more advanced stage. It is a high calorie coal. For this reason, the energy obtained from hard coal is more than the energy obtained from lignite. Since it is more expensive, it is not preferred to be used in homes. It is mined in the Zonguldak region of Turkey. Hard coal is a type of coal that is between anthracite and lignite in terms of its degree of coalification. It is also known as mining coal. It is rich in carbon and volatile substances. The carbon percentage reaches 75 – 90.
Graphite:
Graphite is pure carbon found in nature. The main difference between graphite and diamond is its amorphous structure. Graphite is used in making arc lamp coals and in lubricants. If it is mixed with clay in a certain ratio, a substance is obtained that is used to make pencil nibs.
