Demonstration test of refuse-derived fuel as a supplemental fuel in cement kilns

Technical Report ·
OSTI ID:5627919
Fluff refuse-derived fuel (RDF) from Baltimore County, Maryland, residential solid waste was successfully tested as a supplementary fuel with pulverized coal in a large rotary cement kiln. RDF was produced at the Baltimore County Resource Recovery Facility, a joint project of Baltimore County and the State's Maryland Environmental Service. Tests were conducted by Teledyne National in cooperation with the Lehigh Portland Cement Company. A total of 1400 tons of RDF was burned in a 700 ton-per-day kiln, contributing an average of 30% of the kiln heat. There were four days of initial testing followed by a 27-day extended test of which 20 days involved burning RDF. Cement quality and chemistry, RDF characteristics, and air emissions were determined.
