Utilization Potential of Coal Combustion By-Products-Somerset Power Plant Case Study

摘要

The report documents an 18-month study resulting in analyses of the economic potential of selling ash and ash-derived products from the Somerset Station Power Plant. Twelve different uses were examined for selling the by-products in western New York State and the Toronto Metropolitan market area. Among the applications: fly ash could be used as a partial replacement for cement in concrete mixtures, and as a mineral filler in bituminous pavements; bottom ash could be used as an anti-skid material for winter highway maintenance. The report includes an evaluation of coal combustion by-product applications; a survey of nearly 270 potential users; chemical and physical testing of fly ash; an evaluation of technical specifications for possible market applications; and a determination of raw material markets. All of this information became the basis for evaluating the potential markets for the by-products. Although the study was specifically aimed at marketing Somerset Station bottom and fly ashes, the methodology can be applied to other plants Statewide. In addition, the report discusses a number of by-product applications not feasible for Somerset but which may be useful for other plants.
