Abstract

The relationship between the bulky density of MSW and its lower heating value was clarified as part of research for the establishment of the MSW feed rate stabilization system in stoker-type MSW incinerator. The compaction characteristic of MSW was also examined through experimentation with artificial MSW.<BR>A strong correlation was admitted to exist between bulky density and the lower heating value of MSW. The presumption of the lower heating value became possible by measuring bulky density, although population and regional difference played an influential role in the bulky density concept.<BR>There was great volume change for MSW in the feed part, and this became crucial when considering the compaction of MSW for the presumption of the MSW feed rate. The compaction characteristic curve obtained by the experiment consisted of the part expressed in the second approximation evaluation and in the first approximation equation. Though the curves depended on the composition of the MSW and/or the compaction experimental method, their shapes were basically similar.
