Evaluation of Rotary Drum Air-Classification of Shredded and Unshredded Municipal Solid Waste

摘要

The report describes the capabilities of the Rotary Drum Air Classifier (RDAC) demonstrated at an Albany, NY shredding plant. Air classification using the RDAC has been proposed as an effective and efficient method for producing a better refuse-derived fuel (RDF), with better combustion characteristics and reduced concentrations of metals and chlorine-bearing wastes. During this project a 40-ton-per-hour, transportable RDAC was used to air-classify over 3,000 tons of shredded municipal solid waste (MSW) and over 100 tons of unshredded MSW. The RDAC was found to be effective in removing undesirable, heavy materials from the shredded and unshredded MSW. RDF made using the classifier produced more steam per pound than the usual, unclassified RDF.
