Coal Technology Corporation (CTC) believes that the new CTC high gravity, high production, batch type centrifugal dryer technology can play a significant role in improving the product quality as well as costs of operation in coal processing plants. It is further believed that the new centrifugal dryer technology can form an important part in systems used to clean up the millions of tons of coal fines in refuse piles and ponds. Work has progressed to the point where the new centrifugal dryer technology is nearly ready for commercialization. The primary objective of this project is to prove the concept in a commercial coal processing plant environment. The proof of concept tests will include testing with a variety of coals from different regions. A further objective will be to optimize the efficiency and the cost effectiveness of the new centrifugal dryer technology. To supply some perspective on the ability of the new centrifuges to successfully dry a variety of coals from various coal fields, it was decided that coals ranging from very fine to course size consists and with both low and high inherent moistures would be tested. Coals tested include: Pittsburgh no. 8 seam (Pennsylvania), Pittsburgh no. 8 seam (West Virginia), and Blue Creek Seam (Alabama). 6 figs.
