In coke plants coal is carbonized not combusted to make coke which is used in the manufacture of pig iron by the iron and steel industry Although most of the carbon in the coal carbonized remains in the coke a small amount is retained in byproducts some of which are consumed as energy sources and others as non energy raw materials.Covered coal grindability and specific energy of crushing coal breakage characteristics airborne dust properties and amounts of airborne dust generation Moisture content ash content volatile and fixed carbon content were also deter mined Laboratory crushing tests were conducted on the testing stand the layout of which is shown in Figure 2.
Coal drying Coal preparation plants that employ fine coal cleaning by froth flotation can produce an unacceptable amount of moisture in the product Thermal drying in which the wet coal is dried in the hot gas generated by a coal or gas fired burner is used in some plants to reduce the moisture content Refuse and tailings management.At the same time U S imports of low sulfur coal are projected to grow from the current 28 million tons to almost 90 million tons by the year 2030 The potential need to meet tighter emissions targets may make coal imports an attractive option for coal fired power plants.

Coal is a black or brownish black sedimentary rock that can be burned for fuel and used to generate electricity It is composed mostly of carbon and hydrocarbons which contain energy that can be released through combustion (burning) Coal is the largest source of energy for generating electricity in the world and the most abundant fossil fuel in the United States.Coal facts Coal is an organically derived material It is formed from the remains of decayed plant material compacted into a solid through millions of years of chemical changes under pressure and heat Its rich carbon content gives coal most of its energy content When coal is burned in the presence of air or oxygen heat energy is released.
