A full-scale of combusting and pyrolyzing various mixtures of sludge and refuse derived fuel (RDF) in a multiple hearth furnace was conducted to gather design data for incorporating a resource recovery system in the 15-mgd expansion to a 30-mg water reclamation plant. The objectives of the project were to (a) determine the minimum amount of RDP required for autothermic (self-burning) sludge volume reduction, (b) ascertain whether a fuel gas suitable for firing a lime recalcining furnace can be produced by pyrolyzing RDF and sludge, and (c) find what energy is available from the process for reducing the remaining purchased energy requirements of the water reclamation plant. The testing program involved two distinct operating modes--incineration and pyrolysis. Under incineration, emphasis was placed on causing complete combustion of the solids feed without addition of auxiliary fossil fuel. Under pyrolysis, emphasis was placed on fuel gas production under autothermic operation. The testing equipment and procedures are described. The principal results were that: incineration and pyrolysis of sludge can be accomplished autothermically in a multiple hearth furnace using RDF as an auxiliary fuel source; mixtures of sludge and RDF were autothermically pyrolyzed to produce a fuel gas that was combusted to a temperature in excess of 2000/sup 0/F. The exhaust from combustion of pyrolysis gas is suitable for use in a waste heat boiler to produce 600 psig, 825/sup 0/F steam for electrical power generation; no significant adverse environmental effects; and economic analysis indicates this resource recovery system is cost effective now and will become more so in the future.
