Description
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen.
As a fossil fuel burned for heat, coal supplies about a quarter of the world’s primary energy and two-fifths of its electricity. Some iron and steel making and other industrial processes burn coal.
Coal briquettes have long been produced as a means of using up ‘small coal’, the finely broken coal inevitably produced during the mining process. Otherwise this is difficult to burn as it is hard to arrange adequate airflow through a fire of these small pieces; also such fuel tends to be drawn up and out of the chimney by the draught, giving visible black smoke.
Our coal is suitable for industrial usage and home furnace during winter season due to its Gross Calorific Value is quite high. Made from small particle and dust of coal which is waste from coal mining. With reasonable price, it can be reasonable option for your needs.
