Abstract:

This investigation evaluated current and emerging technologies for the converting waste to energy in applications scaled for use on Army fixed facilities and installations. Technologies reviewed include mass burning of wastes in package modular and field-erected systems use of refuse-derived fuel RDF in new combustion capital and as a supplementary fuel in existing Army-scale central steam generators pyrolytic conversion of waste to a gaseous and liquid fuel and anaerobic digestion of wastes to a fuel gas. The report includes application of a rating system for candidate technologies which considers dependability, practicability, conservation, environmental compatibility, economics, and length of operational history. Use of package waste-to-energy systems and use of RDF as a supplementary boiler fuel are treated in detail. Fully satisfactory methods of surveying installation solid waste to determine energy-recovery system design points are lacking, and currently used methods can result in misapplication of capital. Combustion of unprocessed and minimally processed Once-shredded solid waste in field-erected integrated waterwall combustors equipped with mechanical stokers is currently the superior energy recovery technology. Anaerobic digestion and pyrolytic conversion were found to be unproven but developing.
