The impact that coal characteristics have on power plant performance has become a matter of increasing interest to utilities. Coal quality/plant performance relationships can affect the value of coals, decisions as to coal washing, setting penalties for delivery of coal that fails to meet specifications, and justifying buying better coals (at higher costs) before public utility commissions. The study described in this paper was directed to identifying the impact that changing coal characteristics have on boilers and related coal and gas handling systems. The basis for the study was TVA data for the period 1962-1980. Models were developed for boiler efficiency, boiler availability, and maintenance costs as a function of such coal characteristics as ash, sulfur, and moisture content and boiler age. Boiler load and maintenance efforts were considered as variables in some of the models, but were found not to be statistically significant. Although the results of this study are strictly applicable to only the TVA system, they can serve as guides or first approximations for other utilities.
