Engineering development of advanced physical fine coal cleaning for premium fuel applications. Quarterly technical progress report No. 2, January--March 1993
The main purpose of this project is engineering development of advanced column flotation and selective agglomeration technologies for cleaning coal. Development of these technologies is an important step in the Department of Energy program to show that ultra-clean fuel can be produced from selected United States coals and that this fuel will be a cost-effective replacement for a portion of the premium fuels (oil and natural gas) burned by electric utility and industrial boilers in this country. Capturing a relatively small fraction of the total utility and industrial oil-fired boiler fuel market would have a significant impact on domestic coal production and reduce national dependence on petroleum fuels. Significant potential export markets also exist in Europe and the Pacific Rim for cost-effective premium fuels prepared from ultra-clean coal. The replacement of premium fossil fuels with coal can only be realized if retrofit costs, and boiler derating are kept to a minimum. Also, retrofit boiler emissions must be compatible with national goals for clean air. These concerns establish the specifications for the ash and sulfur levels and combustion properties of ultra-clean coal discussed below. The cost-shared contract effort is for 48 months beginning September 30, 1992, and ending September 30, 1996. This report discusses the technical progress made during the second 3 months of the project, January 1 to March 31, 1993.
