Different Types of Coal. It is important to be aware that "coal" can cover a variety of finished products of differing values and requiring different treatment. The main division is between "coking" coal and "energy or steaming" coal. Coking coals, used to make coke for use in blast furnaces, have particular properties which allow it to form a ...
Coal preparation Pulverizers Unit 17 Pulverized coal system 1. Large coal particles are crushed to <10 mm [Crusher] 2. Then it is ground to below 75 micron () in an equipment called Pulverizing Mills [Mills] 3. This coal is conveyed by combustion air to the coal burners to burn in the furnace [storage/conveying] Types of PF Systems 1.
b) Thermal power plants:In thermal power plants the heat energy produced by burning fossil fuels like coal, petroleum or natural gas is used to heat water and change it into steam which rotates the turbines of generators to produce electricity. c) Hydro power plants:In hydro power plants water from rivers are stored by constructing dams.
