- W4212916516 abstract "The objectives of the project were to: demonstrate stable, reliable, long term, continuous operation of a pressurized, downflow, entrained, laboratory scale coal gasification pilot plant; develop a mathematical model of the gasification reactor which will characterize the gasification properties of the coals and correlate the data; and apply the model to studies of integrated gasification, combined-cycle efficiencies. A total of 296 test runs were made for a total of 800 operating hours. Cold gas efficiencies of 73 percent at specific gasification rates of 115 pounds coal/hour ft/sup 3/ atmospheres have been achieved. Extensive equipment modifications have been made to overcome problems with non-uniform coal feeding, feed injector plugging, refractory overheating, heat recovery section plugging and scrubber discharge plugging. An extended series of runs on a range of feed coals and char were conducted. Using the results, a semi-emperical mathematical model was developed. Mathematical models of the entrained gasifier integrated in various ways with a combined cycle system have been developed and used to study the effect of mode of integration, coal type, gasifier heat loss and gasifier steam feed rate on combined cycle performance. As part of the project Ford Bacon and Davis of Utah Inc. (FBDU) performed a detailed cost and engineering analysis of the scaled up high rate entrained gasification process. Their conclusions are favorable based on the simplicity of the process, thermal efficiency and the use of commercially-proven equipment. (LTN)" @default.
