Abstract

The U.S. Department of Energy is currently sponsoring a variety of projects aimed at developing advanced systems for power generation using coal gasification as the central conversion process. These systems include both gas turbines and fuel cells as power generating devices and emphasize hot gas cleanup for equipment protection and environmental control from coal contaminants. Gasification projects in the DOE program cover a range of scales from laboratory investigations to PDU scale plants. Fundamental studies of gasification reactions, ash chemistry, transport processes, and modeling are being conducted to uncover potential improvements that may be made to gasification processes and to ways of reducing cleanup burdens on downstream equipment. Several PDU scale projects are being sponsored to further promising processes. Gas stream cleanup emphasize hot control of particulates, sulfur, alkali, and trace species which may damage power generation equipment. A systems approach has been adopted in formulating strategies for these programs. This approach and brief description of projects in gasification and cleanup will be presented.
