Liquid-fed ceramic melter testing for the Hanford Waste Vitrification Plant waste.

摘要

The HWVP Project is proceeding aggressively on simultaneous design and development paths. The major development goals are intended to support design and process definition, waste form qualification, and site and permitting activities. In achieving these goals the HLW glass producer shares many of the challenges of the commercial glass industry. A reliable feedstream with consistent composition and physical properties is required to maximize throughput. The prevention of secondary phases such as spinels, insoluble alkali salts, and reduced metals is crucial to maintain a high on-stream factor and long melter life. The treatment of process off gases to maximize process recycle and eliminate environmentally harmful gases and particulate matter is a necessity. Finally, by thoroughly understanding the process and its control, a high-quality glass can be produced that will meet disposal requirements. This paper focuses on liquid-fed, ceramic-lined melter and off-gas treatment equipment testing to date. Following the process description and related testing requirements, the results of melter testing are presented with emphasis on FY 1988 test results. 4 refs., 5 figs., 6 tabs.
