Reducing the Moisture Content of Clean Coals, Volume 3: Belt Filter Press contains the results of an EPRI investigation into the performance of an alternative clean coal dewatering device. Investigators at EPRI's Coal Quality Development Center (CQDC) designed test so that mathematical relationships predicting filter cake moisture and solids capture could be developed. They also compared the economics of installing and operating a belt filter press with a vacuum disc filter, which is its nearest equivalent. For 100M [times] 0 clean coal from the Upper Freeport seam, the belt filter press produced filter cake with an average moisture content of 30 percent. This moisture is 5 to 10 percentage points higher than moistures from a vacuum disc filter. Economic analysis shows that the belt filter press costs an additional $72,000 a year to operate in place of a vacuum disc filter.
