Investigation of Engineering and Design Considerations in Selecting Conveyors for Densified Refuse-Derived Fuel (dRDF) and dRDF: Coal Mixtures

摘要

An engineering evaluation and experimental program involving several types of conveyors applied to blends of densified refuse-derived fuel (dRDF) and blends of dRDF and coal, was conducted by the National Center for Resource Recovery. The final project report discusses the properties of waste affecting convey ability and presents experimentally determined values or observed characteristics. A procedure was selected for the assessment, selection, and operation of belt conveyors based on spillage rate. Corroborating experimental results from a recirculating test rig operated with samples of dRDF and a blend of dRDF and coal over a range of belt configurations, velocities and flow rates were also presented. Experiments conducted on a vibrating pan conveyor over a range of frequencies and stroke length, and on a small apron conveyor, were described and the test results analyzed. (Author)
