Cooling Effect of Coal Drying on CO2 Mass,(PDF) Effect of Coal Drying on Emissions | Nenad Sarunac,,This process reduces coal moisture, sulfur, mercury, and ash content and thereby should increase unit efficiency, reduce pollution and reduce CO2 emissions. Performance tests were conducted pre and post-DryFineTM installation to quantify the effect on unit operation and gas phase emissions. Operation of the DryFine process resulted in lower coal feed rates and lower flue gas volumes. The lower,drying of coal in coal mill,Coal Drying Improves Performance and Reduces Emissions. Additionally, with less fuel moisture, more complete drying of coal can be achieved in the mill. This results in increased mill exit temperature (the temperature of the coal and primary air mixture at mill exit), better conveying of coal in the coal pipes and less coal pipe plugging problems.Lehigh University: Energy Research Center: Current,,"Coal Drying Improves Performance and Reduces Emissions" "Effect of DryFine(TM) Low Temperature Coal Drying Process on Emissions from a Coal-Fired Power Plant" "Technology Breakthrough Paper: Coal Drying" FOSSIL ENERGY CATEGORIES • Introduction • Coal Drying • On-Line Coal Monitoring • Coal Pipe Balancing • Process Optimization • MATS Compliance • Carbon
