Limestone Influence on PAH Emissions from Coal AFBC ...

Jan 01, 2002· Limestone incorporation to coal feed during coal atmospheric fluidized bed combustion (AFBC) to control legislated emissions promotes the polyaromatic hydrocarbon (PAH) emissions. This is a fact that has been corroborated working in a laboratory pilot plant at the same conditions used at the coal FBC power stations.

Power plant emissions of sulfur dioxide and nitrogen ...

The reduction in SO 2 and NO x emissions through the late 2000s was primarily the result of coal plants employing strategies to reduce emissions, not a reduction in the use of coal overall. In fact, coal generation set record highs in 2007 when significant SO 2 reduction was already underway.
