PDF FINE COAL DRYING AND PLANT PROFITABILITY

Where coal is burned in oxygen rather than air it means that the flue gas is mostly CO2 and hence it can more readily be captured by amine scrubbing at about half the cost of capture from conventional plants A number of oxyfuel systems are operational in the USA and elsewhere and the FutureGen 2 project involves oxycombustion Mar 11 2010 Washington DC An innovative coaldrying technology that will extract more energy from high moisture coal at less cost and simultaneously reduce potentially harmful emissions is ready for commercial use after successful testing at a Minnesota electric utilityThe DryFiningTM technology was developed with funding from the first round of the US Department of Energys Clean Coal Power
