As new coal fired utilities are built, they will utilize technologies specifically focused on reducing emissions, such as gasification and clean coal technologies (CCT). While these technologies do an exceptional job at reducing emissions, they generate large quantities of by-products. Since CCT is quite different from conventional pulverized coal combustion (PCC), it is not surprising that CCT byproducts are very different from PCC byproducts. Many industries use PCC byproducts because they have been available for many years and their uses are well understood. Uses for CCT byproducts are not nearly as well understood, and it will take time to generate the knowledge as well as the utilization markets.
The following Flash movies - courtesy of the UK CAER's CCT site - demonstrate the various CCT processes utilized at coal fired power plants to enhance the efficiency and environmental acceptability of coal preparation and use.
