The layout of your coal grinding system must take into account the available heat sources for drying the raw coal as well as the fire and explosion hazards of coal and coal dust. The entire grinding plant must therefore be shock-resistant and equipped with a number of explo-sion relief valves. From the raw coal .

FIGURE 7-2. Coal production and consumption in the U.S. in the past 150 years. [Source: Energy Information Administration.] Coal Formation As described in the general discussion of the carbon cycle (Chapter 6), coal was formed from prehistoric plants, in marshy environments, some tens or hundreds of millions of years ago.
In coal-fired power plants coal mills are used to pulverize and dry to coal before it is blown into the power plant furnace. The coal is feed into the coal mill through a central inlet pipe where gravity is used to lead the coal to the bottom of the mill, where the grinding table and some heavy rollers pulverizes the coal to particles.

INDIAN SCENARIO OF COKING COAL PLANTS 9Prior to 1950, there were no Beneficiation plants, since selective mining was in practice. 9The first Indian coal washery was set up at West Bokaro in 1951, followed by the second one installed at Jamadoba in 1952 – both by M/s Tata Iron and Steel Limited.
transport the coal dust in special vehicles for distances of up to 1000 kilometres. The large-scale substitution of rare energy sources with coal dust is possible with centralised coal grinding plants in structural developed regions. Decentralised supply The mobile coal grinding plant developed by Loesche closes the coal dust supply gap.
Coal gasification is the process of producing syngas–a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), natural gas (CH 4), and water vapour (H 2 O)–from coal and water, air and/or oxygen.. Historically, coal was gasified to produce coal gas, also known as "town gas".Coal gas is combustible and was used for municipal lighting, and heating ...
