Synthetic Aggregate From Incinerator Residue by a Continuous Fusion Process.

摘要

A pilot plant demonstration was carried out on a simple and highly inexpensive system for converting municipal incinerator residues into dense road aggregates. Residues were hammermilled,burned-out,rapidly fused in a continuous manner,then cooled and crushed to produce good quality road aggregate for use in bituminous concrete. Residual aluminum in the crushed aggregate presently would preclude its direct use in Portland cement concrete. Full-scale plant design and cost estimates were prepared. These show that the complete residue fusion system producing 120tons/day of aggregate in conjunction with a typical 600ton/day refuse incinerator would cost $300,000. Operating costs for the aggregate plant including capital charges would be $4to $5per ton of aggregate.
