Test Procedures for the Determination of the Gross Calorific Value of Refuse and Refuse-Derived-Fuels by Oxygen Bomb Calorimetry. Summary of the 1977 Fiscal Year Results

摘要

Gross calorific values have been determined for refuse-derived-fuels (RDF) from two manufacturers, Teledyne National and Combustion Equipment Associates. Test procedures used are modifications of those used for coal and coke. The calorific values (moisture- and ash-free basis) obtained for Teledyne National RDF ranged from 24.51 to 25.20 MJ kg exp -1 (10,539 to 10,835 Btu 1b exp -1 ) with a standard deviation of 0.8 percent. The calorific values (moisture- and ash-free basis) of Combustion Equipment Associates ECO-FUEL II RDF range from 21.93 to 22.16 MJ kg exp -1 (9427 to 9528 Btu 1b exp -1 ) with a standard deviation of 0.4 percent. Results of 23 laboratory samples are presented at various stages of sample preparation which were derived from single field samples from each of the two sources. Calorimetric results based on an equilibrated laboratory sample are presented along with some semi-quantitative spectrochemical results. The results indicate that the techniques of oxygen bomb calorimetry can be successfully applied to a non-homogeneous refuse stream after considerable processing to prepare a homogeneous refuse-derived-fuel.
