A new, emerging flue gas desulfurization technology has been described by the IAEA. It is a radiation technology where an intense beam of electrons is fired into the flue gas at the same time as ammonia is added to the gas. The Chendu power plant in China started up such a flue gas desulfurization unit on a 100 MW scale in 1998.

In order to eliminate the SO 2, the flue exhaust gases from a coalfired power plant are usually passed through a spray of limestone slurry in the scrubber. The resultant reaction typically traps over 90% of the SO 2. Nearly 80%–85% of the global FGD units set up in power plants use wet limestone scrubbing compared to other technologies.
In June 2006, NRG Energy proposed plans to build a new 744 megawatt pulverized coal power plant at its existing 1,614 MW Limestone Station, located in Jewett about 120 miles northwest of Houston. The new unit, named Limestone III, would cost billion and enter service in 2012, if allowed to proceed.

Thermalbased power plants can produce electricity from coal or other fuel sources. The coalfired process requires three different steps to turn energy released from burning coal to generating electricity for consumption. Coal fired power plants, while producing power, require a lot of water and produce a lot of pollutants like ash and CO2.

For older coalfired power plants this included installing scrubber systems in the smokestacks to filter sulfur from the exhaust. "In 1985, Plains Electric built a power plant in nearby Prewitt, New Mexico and the project manager needed a source for limestone that would pass the qualifications required for the power plant emissions," he says.

Texas has a wide variety of energy sources. Once dominated by natural gas and coal, the power mix has been changing rapidly. Wind generation replaced coal in the number two position in 2017. ERCOT has also approved the planned connection of much new generation capacity to the Texas electric grid, none of it coal. The permitted new connections to the grid include 2,000 megawatts from solar ...
It depends on the type of coalfired boiler. If it''s a Bubbling Fluidised Bed (BFB) or Circulating Fluidised Bed (CFB) boiler then limestone could be added to the bed material to give a desulphurising effect. If it''s a Pulverised Fuel (PF) boiler...
Higher efficiencies mean that less fuel is used to generate the rated power, resulting in lower costs and the formation of fewer greenhouse gases. For example, a 60 percentefficient gasification power plant could cut the formation of carbon dioxide by 40 per cent, compared to a typical coal combustion plant.
