Coal cleaning test facility campaign report No. 4: Kentucky No. 11 seam coal
The cleanability characteristics of Kentucky No. 11 Seam coal are the subject of Campaign Report No. 4 issued by EPRI's Cleaning Test Facility (CCTF). In July 1983, the CCTF cleaned Kentucky No. 11 Seam coal in three different flowsheets with the goal of reducing potential sulfur dioxide (SO/sub 2/) emissions. Test results show that coal cleaning is able to lower potential SO/sub 2/ emissions by about 50 percent (from nearly 10 lb/MBtu in the raw coal to about 5 lb/MBtu in the clean coal) with energy recoveries greater than 80 percent. Boiler ash loadings, on a lb/MBtu basis, are also significantly reduced - a 90 percent or greater reduction can be achieved with coal cleaning. Based on empirical indices, coal cleaning does not significantly affect the slagging and fouling potential of Kentucky No. 11 Seam coal. However, the Tennessee Valley Authority which was burning Kentucky No. 11 Seam coal raw was having severe slagging and fouling problems, causing a significant derating at its Cumberland Power Station. When TVA began burning a blend of cleaned Kentucky No. 11 Seam and Kentucky No. 9 Seam coals, they saw improvements in terms of slagging and fouling, resulting in a recovery of most of the derated capacity. 11 refs., 24 figs., 24 tabs.
