Coal Sorting. Coal sorting is a process of separating a single coal stream into two or more streams of different qualities. Coal sorting reduces the total tonnes of coal which has to be washed, assisting the mine's profitability by: Reducing the capital cost of a green field site, allowing total output to be achieved with a smaller washery

UP: Coal Glossary

Clean Coal Technology Because of environmental pollution concerns from the burning of coal, increased efforts are being made to develop better emission control or reduction technologies. These technologies apply to cleaning impurities from the coal itself, improving the effectiveness of the burning process, and/or improving the pollutant recovery systems for the escaping products of combustion.

Fossil fuel power station - Wikipedia

A fossil fuel power station is a thermal power station which burns a fossil fuel, such as coal or natural gas, to produce electricity.Fossil fuel power stations have machinery to convert the heat energy of combustion into mechanical energy, which then operates an electrical generator.The prime mover may be a steam turbine, a gas turbine or, in small plants, a reciprocating gas engine.
