Test procedures for the determination of the gross calorific value of refuse and refuse-derived-fuel by conventional bomb and large bomb calorimetry :

Abstract

This report provides the results of investigations during fiscal year 1979 to develop test procedures for the determination of the calorific value of refuse and refuse-derived-fuel (RDF) by means of oxygen bomb calorimetry. The results of' 138 calorimetric measurements are discussed, along with 32 calorimeter calibration measurements, for 20 different RDF samples. In addition, determinations have been carried out on these RDF samples for air dry loss, residual moisture, furnace ash, bomb ash, and sulfur content to correct the calorimetric data for their presence; the latter group of measurements amounts to 283 experiments. The calorimetric (and related) measurements can be categorized into five classes: (1) measurements carried out in conjunction with ASTM round robin testing of RDF-3, (2) measurements on an Americology RDF extracted using both selective and non-selective sampling methods, (3) measurements required to compare data obtained from the small (2.5 gram capacity) and large (25 gram
