The purpose of the present study was to develop for two major cities, design recommendations and procedures for the disposal of refuse, a low sulfur fuel, with heat recovery in utility grade boilers. An earlier study in this area resulted in the identification of optimal system design configurations and quantification of benefits to the environment and the economy. The program has applied that knowledge to specific case study areas. Arrangements with two cities having high SO2 burdens and growing solid waste burdens were made; these were Philadelphia, Pennsylvania, and Cleveland, Ohio. Information required for the study was collected and analyzed. Specific design packages were then developed for each city. The report presents projections describing the future nature of the city refuse-fuel inventories, specific recommendations as to plant types, sizes, and sites, cost analyses of operations involving the utilization of such systems, and estimated reduction in SO2 and particulate emissions. From these data, the conclusion can readily be drawn that the systems recommended would be more cost-effective than the methods that are now in use. (Author)
