This fuel from Carboniferous period is now one of the most common heating up materials. Is suitable to use for central heating at house, glass houses and to burn in furnaces to melt steel. Extracting process is very long if tunnels collapse often it is also very dangerous. All this influence the costs of mining and the price of distributed coal. Poland and China are now the biggest producers of so called black gold. Because of denationalization of ironworks and foundries the extraction of coal decreases however, once again it becomes more and more popular as a heating material at homes and flats. Coal is much cheaper than natural gas or fuel oils.

Energetic features (calorific value) are strictly connected to carbon concentration in coal mined. Our company sell only coal that’s concentration of carbon is over 80%. It makes good calorific value and susceptible to combustion.
