Coal Past, Present and Future From the first lightbulb to

In addition to electric power, coal is used for steelmaking and cement production. Coke, produced from coal, is used in blast furnaces for smelting of iron ore to produce molten iron, a primary component of steel. The molten iron is combined with scrap steel and a flux (usually limestone) in a basic oxygen furnace, producing pure liquid steel

Low-CO2 cement production with activated clay

CO2 is a natural constituent of limestone, the main component of cement. For each ton of cement clinker produced, around 790 kilograms of process-related CO2 is emitted. Around two thirds of this results from the limestone used, which releases CO2 in a chemical reaction in the production process. At the same time the process requires large amounts of energy, because for the production of

Carbon Dioxide Emission Factors for Coal

Carbon, by far the major component of coal, is the principal source of heat, generating about 14,500 British thermal units (Btu) per pound. The typical carbon content for coal (dry basis) ranges from more than 60 percent for lignite to more than 80 percent for anthracite. Although hydrogen generates about 62,000 Btu per pound, it accounts for only 5 percent or less of coal and not all of this

COAL GRINDING AND DRYING IN CEMENT INDUSTRY

The preparation of coal in cement works comprises the grinding and drying of raw coal delivered to the works. In cases where the coal consumption rates are high and coal from different sources are used, it is advantageous to blend the various coals in conjunction with stockpiling so as to obtain a fuel that is physically and chemically as closely uniform as possible and thus, to achieve well
