“…Two of the 2.5 kg samples from each group were milled to 2 mm particle size and then, to obtain gram-size test samples, each of these parent samples was subdivided using a rotary riffler rather than the usual method of coning and quartering. The results, which we believe resolve the processing and sampling questions, are discussed in detail elsewhere [5]. In brief, the results are as follows:…”

“…The resulting % CV, 0.4%, is the measurement error of the calorimeter with an actual sample of MSW. For comparison, the % CV for measurements of -tJi" on the corresponding pairs of "identical" gram-size samples of MSW obtained with the same bomb calorimeter used in the cellulose measurements was 0.5% [5]. Average corrections for the processed MSW measurements are listed in the fourth column of table 3.…”

“…5 Twelve and one-half minutes prior to ignition, the flow of water to the quick-cool heat exchange tube is diverted to the calorimeter vessel and the water remaining in the quick-cool tube is flushed out with compressed air. The combustor is then flushed with oxygen for 10 minutes at a flow rate of 30 L/min.…”

A large capacity calorimeter was designed and constructed in order to determine the enthalpies of combustion of kilogram-size samples of municipal solid waste (MSW) in flowing oxygen near atmospheric pressure. The combustion of the organic fraction of the samples was complete to greater than 99.9+%. The percent coefficient of variation (100 X standard deviation/average), % ev.of calibration measurements using microcrystalline cellulose was 0.2%. The % CV of the measurements of the enthalpy of combm.tion of a processed MSW s.ample was 0.4%. The combined systematic errors due to departure from usual design standards and conventional operating procedures is estimated to be less than 0.4% of the calorific value.
