Advanced physical fine coal cleaning: Final report

Technical Report · Tue Dec 01 00:00:00 EST 1987

OSTI ID:5331256

The contract objective was to demonstrate Advanced Energy Dynamics, Inc., (AED) Ultrafine Coal (UFC) electrostatic physical fine coal cleaning process as capable of: producing clean coal products of no greater than 2% ash; significantly reducing the pyritic sulfur content below that achievable with state-of-the-art coal cleaning; recovering over 80% of the available energy content in the run-of-mine coal; producing product and refuse with surface moisture below 30%. Originally the demonstration was to be of a Charger/Disc System at the Electric Power Research Institute (EPRI) Coal Quality Development Center (CQDC) at Homer City, Pennsylvania. As a result of the combination of Charger/Disc System scale-up problems and parallel development of an improved Vertical-Belt Separator, DOE issued a contract modification to perform additional laboratory testing and optimization of the UFC Vertical-Belt Separator System at AED. These comparative test results, safety analyses and an economic analysis are discussed in this report. 29 refs., 25 figs., 41 tabs.
