CE Concrete saw a window of opportunity in the 1980's to join the greener power generation. With the help from Volvo wheel loaders and articulated haulers they are able to contribute to the greener power movement by extracting limestone that is used by coal power plants to scrub exhaust emissions and for dust control in underground coal
Coal-burning power plants already use limestone scrubbing to remove sulfur dioxide from their smokestack emissions, he said. It might be possible to combine sulfur and carbon dioxide removal in one step or in successive steps. Alternatively, Accelerated Weathering of Limestone might be more appropriate for power plants that burn
Limestone Electric Generating Station is a coal-fired power station owned and operated by NRG Energy near Jewett, Texas. On Oct. 9, 2007, the Texas Commission on Environmental Quality (CEQ) released the draft air permit for the plant. Environmental groups are mobilizing against the plant; NRG is

Gas has lately eclipsed coal as the most used fuel in U.S. power generation, according to the Energy Information Administration, and many plants across the country have opted to convert to the fuel. NRG said it would cost millions to convert its Limestone plant to gas, and that switching to PRB coal would incur no significant cost penalty.

Flue gas desulfurization Flue gas desulfurization is commonly known as FGD and is the technology used for removing sulfur dioxide (SO 2) from the exhaust combustion flue gases of power plants that burn coal oroil to produce steam for the turbines that drive their electricity generators. The most common types of FGD contact the flue gases with an alkaline sorbent such as lime or limestone
By Brad Buecker, Contributing Editor. Stricter environmental regulations are forcing many utilities to install flue gas desulfurization (FGD) systems to control sulfur dioxide (SO 2) emissions below levels that can be attained by burning Powder River Basin (PRB) coal

Another by-product of Coal use, which we've touched on only once or twice, is the "sludge" generated by at least some types of "Flue Gas Desulphurization", "FGD", devices, which, by regulation, are now being installed on all new Coal-fired electric power plants, and which have been retrofitted on most existing ones.
use of limestone in coal power plant. How it Works: Water for Coal Union of Concerned Scientists. The choice of cooling system used in a coal plant affects not only its water requirements but also the efficiency of the power plant as a whole.
Fluidized bed combustion (FBC) is a combustion technology used to burn solid fuels. In its most basic form, fuel particles are suspended in a hot, bubbling fluidity bed of ash and other particulate materials (sand, limestone etc.) through which jets of air are blown to provide the oxygen required for combustion or gasification.
