A comprehensive program is underway to evaluate the Westinghouse fluidized bed coal gasification system for a combined cycle power plant. Such a plant is expected to be lower in capital costs, lower in pollutant emissions and have the potential for higher overall plant efficiency when compared with conventional power plants. A 15 ton/day Process Development Unit (PDU) has been constructed at Waltz Mill, PA, to investigate the coal gasification process, and testing has been in progress since early 1975. Most of the reactor design criteria initially specified for the PDU have been realized in the test operations completed to date. Test runs have been conducted with a variety of coal and char feedstocks including non-caking or mildly-caking Wyoming and Indiana coals as well as highly caking Pittsburgh coals. Steady state tests of extended times have been achieved with high carbon utilization efficiencies and production of acceptable product fuel gas. Plans are in progress to demonstrate the process on a larger scale.
