Coal Drying Improves Performance and Reduces Emissions

2017-9-6  The outdoor stockpile coal drying system was designed to provide coal containing approximately 28 to 30 percent moisture for the test burn. Coal drying was accomplished by heated air (approximately 110oF) delivered by a network of pipes located beneath the coal pile. The flow rate of drying air was approximately 53,000 CFM. The coal was dried for about 50 days and during that time period, the coal moisture was reduced by 6.1 percent, from 37.5 to 31.4 percent. After 50 days of drying, the coal was visibly drier and dustier than the coal typically stacked out and reclaimed by the Coal Creek Coal
