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.
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...

The 2011 Environmental Defense Fund report, "Mercury Alert: Cleaning up Coal Plants for Healthier Lives" found that 25 plants alone are responsible for nearly a third of all mercury emissions in the power sector, while providing .
, the flue exhaust from a coalfired power plant is commonly bubbled through a mixture of lime or limestone and water. The resultant reaction typically captures 95 % or more of the SO 2. Approximately 8085 % of worldwide FGD units installed in power plants use wet limestone scrubbing vs. other technologies. What happens to the SO 2 captured in ...
Oct 05, 2010· Because coal power derives all of its energy from producing steam, dry cooling has a greater impact on the efficiencies of coalfired plants than on most natural gasfired ones., Coal boilers also use small amounts of water for boiler blowdown. In this process, water is bled from the boiler to get rid of impurities that accumulate and form ...

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.
