Coal is one of the most important fossil fuels, which is classified as a sedimentary material. Carbon-rich substances, usually brown or black. About 40% of the world’s electricity is generated by burning it. This statistics is much higher in some countries, for example the Netherlands about 94%, South Africa about 92%, China about 77% and Australia about 76% of their electricity using this fossil fuel. It has played an important role in recent centuries, not only because of its electricity generation but also because of its important role in the production of steel, cement and other industrial activities.It is generally divided into four categories: anthracite, bituminous, subbituminous and brown coal. This classification is based on the type and amount of carbon and the thermal energy released by combustion. The degree of hardness also depends on the amount of pressure and temperature that has been applied to the plants over the years.Anthracite: It has about 86% to 97% carbon and has the highest calorific value among all types of coal. This material is mainly used by metal related industries. The amount of reserves of this substance in the world is less than 1% of the total coal reserves.Bituminous: This type contains about 45% to 86% of carbon. This material is 100 million to 300 million years old in the United States. Bitumen is commonly used to generate electricity in power plants. It is also used as a fuel and as a raw material in the iron and steel industry. About 53% of the sources of this material are related to this type.
Types of coal
burning. This type accounts for about 30% of the world’s coal reserves and is mostly used in the cement industry.Lignite: This material has about 25% to 35% carbon and in this category has the lowest calorific value compared to other types of this material. The coal is relatively young and has not been exposed to extreme heat or pressure. This material is easily crushed and has a high humidity, and therefore its calorific value is low. It accounts for about 13% of the world’s total reserves of this substance.
According to the conditions of different countries, especially the following countries:
China’s coal prices hit record highs after 60 mines closed due to rain, floods and landslides
And India has multiplied coal imports several times to tackle energy shortagesWith the increasing demand for coal in various countries for energy storage and also the high demand of power plants to buy coal, the price of coal has increased significantly and has reached its highest level in the last 13 years. The next case is the Russian war, which has led to a significant increase in coal prices. But we can still provide you with coal at a different price.
