Analysis of waste for combustion: the case of Osaka City, Japan

摘要

An analysis of the composition of waste for combustion is presented. The experimental protocol adopted for this study is the one used in Osaka city. Results over several years are given. A new format by which to describe physical, proximate and elemental composition as well as heat properties, is presented. Empirical values of the proximate composition of combustible components are given. These values are for composition estimates of some wastes. It is not clear exactly where and how much ash is generated in a municipal waste incinerator. Waste composition data enable the ash mass balance of an actual incinerator to be estimated. The methodology of elemental analysis is discussed. Chlorine and sulfur were determined by the tube combustion and bomb combustion methods. Comparisons suggest that the tube combustion method is preferable for pollution assessment.
