Coal is a complex combination of materials, and the combination can greatly differ from one formation or deposit to another. These differences result from: 1. The varying types of vegetation from which the coal originated. 2. The depths of burial, and the temperatures and pressures at those depths. 3.
Sulfur in coal exists in inorganic and organic forms, the former being mostly pyritic sulfur. Total sulfur contents in major coalfields are in the range of roughly wt%. In coal combustion, to generate electric power and process heat, the sulfur is emitted as SO2, which is seen as one of the main causes of acid rain. This effect has led ...
Coal Cleaning Process Description12,9 Coal cleaning is a process by which impurities such as sulfur, ash, and rock are removed from coal to upgrade its value. Coal cleaning processes are categorized as either physical cleaning or chemical cleaning. Physical coal cleaning processes, the mechanical separation of coal from its
Other articles where coal processing is discussed: coal mining: Coal preparation: As explained above, during the formation of coal and subsequent geologic activities, a coal seam may acquire mineral matter, veins of clay, bands of rock, and igneous intrusions. In addition, during the process of mining, a portion of the roof and floor material.

Since the reserves of good coking coals are being depleted, coal preparation is necessity for a modern cokeoven plant. In addition, with the development of large capacity units in cokemaking and blast furnace technology, the better quality and uniformity of feed coals has been required. The Coking Process of Coal in the Oven Chamber
Fig. : A coal mine Coal Gas Coal gas is obtained during the processing of coal to get coke. It is used Coal gas was used for street lighting for the first time in London in 1810 and in New York around 1820. Now a days, it is used as a source of heat rather than light. These days, bitumen, a petroleum product, is used in place of coaltar
