Advanced coal gasification system for electric power generation. First quarterly progress report, FY-1080, October 1-December 31, 1979
The results of PDU tests TP-025-1, -2, and -3 are reported. A review of the data and the effect of various modifications on cyclone deposits was conducted. It is tentatively concluded that the mechanism of deposit formation is the result of sticky particles or liquid droplets out of the combustion and/or gasification zone impacting on the hot refractory cyclone walls as a result of change in direction of flow. Also, there must be different glue generated from Ohio No. 9 coal as compared with Pittsburgh seam coal. The most effective modification to date for alleviating cyclone deposits has been a water spray nozzle which was installed in the freeboard area of the gasifier to quench particles with a liquid film and render them nonsticky. During test TP-025-2 water spray in the freeboard area of the gasifier was used to cool the gas and particles from 1800/sup 0/F to 1300/sup 0/F. At this temperature, the deposit was practically eliminated. However, long-duration tests with Pittsburgh seam and Ohio No. 9 coals are necessary before any firm conclusions can be drawn about the effect of water spray. Significant progress was made in the construction of the cold-flow, scale-up facility. In addition, studies were made on the reactivity of various chars in the laboratory fluidized bed. Leaching studies on ash from test TP-020-2 agglomerates were completed using Westinghouse standard leach acts.(LTN)
