Experience with coal-water mixtures
A demonstration of coal-water mixture at Florida Power and Light's Sanford plant was a technological success, but not without some difficulty. Extensive accumulation of melted ash, and atomizer wear, made the demonstration only marginal economically. Falling oil prices in 1981-82 made the conversion to COM even less attractive. Combustion tests on the suitability of several candidate coal mixtures concluded that the quantity and characteristics of the ash in the coal is the most important variable in predicting fuel performance. An examination of the characteristics of CWM with various coal-water ratios shows that the ''water penalty'' is not as severe as believed. Yet it is NOT a foregone conclusion that CWM fuels will be economical in the future.
