Coal pollution mitigation - Wikipedia

Coal pollution mitigation, sometimes called clean coal, is a series of systems and technologies that seek to mitigate the health and environmental impact of coal; in particular air pollution from coal-fired power stations, and from coal burnt by heavy industry.. The primary focus is on sulfur dioxide (SO 2) and nitrogen oxides (NO x), the most important gases which caused acid rain; and

A. Abutment - In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.

Flue gas desulphurization detailed process

Feb 16, 2015 · Flue-gas desulfurization (FGD): Flue gas is the gas exiting to the atmosphere via a flue, which is a pipe or channel for conveying exhaust gases from a fireplace, oven, furnace, boiler or steam generator 7. Flue-gas desulfurization (FGD) is a set of technologies used to remove sulfur dioxide (SO2) from exhaust flue gases of fossil- fuel power

Wet Flue Gas Desulfurization (WFGD) unit based upon spray scrubber has been widely employed to control SO 2 emissions from flue gas in coal-fired power plant. To clarify the dependence of desulfurization performance on inter-phase transfer behaviors with non-ideal contacting patterns of flue gas and slurry droplets, three regions in spray scrubber are distinguished in terms of gas-slurry flow

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.
