Preparation of Coal for Coal-Water Mixtures

摘要

Preparation of several coal samples was undertaken to provide sufficient quantities for a matrix of tests designed to evaluate equipment for formulating, handling, and burning coal water mixtures. This work was done for Gulf Research and Development Company (GR and DC), which is a subcontractor to Combustion Engineering Incorporated (C-E), for work on the Department of Energy (DOE), Contract DE-AC22-82PC50271, Combustion and Fuel Characterization of Coal Water Mixtures. Three coal samples of approximately five tons each were beneficiated to level 4 (2% +- .4% ash, dry basis) in an 8-in. heavy-medium cyclone for preliminary evaluation. Based on a detailed washability analysis provided by GR and DC, a preliminary run on each of the samples was conducted to provide data for predicting the operational parameters required to produce the desired product. Using the predictive data, processing the remainder of each sample was completed. Additional quantities of coal selected from the original sources will be processed in larger quantities. 4 references, 10 figures, 5 tables. (ERA citation 09:035120)
