Hard coal
Hard coal is composed of several basic elements: carbon, hydrogen, oxygen, nitrogen, phosphorus and sulphur. It is a sedimentary rock of plant origin, created mostly in the Carboniferous period from plant material that has been coalified in anaerobic conditions. According to the carbonification level of fuels that depends on their percentage content of pure carbon, the fuels can be divided into several types: peat (ca. 39 C%), brown coal (ca. 46 C%), flame coal (ca. 55 C%), gas coal (ca. 54 C%), orthocoking coal (ca. 59 C%), semicoking coal (ca. 60 C%), anthracite (69 C%).
Today, hard coal is one of top fossil fuels. Its quality depends on many parameters, among others on its calorific value, ash content, and sulphur content. The hard coal offered by our company comes from Kuzbas, namely the Kuznetsk Coal Basin in Russia, located in the southern part of central Siberia. The coal that we import comes from trusted mines which ensure stable required parameters including high calorific value, low ash and sulphur content, which makes it more environmentally-friendly and safer for furnaces.
