Abstract
A new CFD-code "3d-MSW" to predict the waste bed combustion in the stoker-type Municipal Solid Waste Incinerators (MSWI) was developed. 3d-MSW was validated by comparison with the combustion tests in a pilot incinerator. The calculation results could predict the waste bed combustion under not only normal air but also oxygen enrichment air. Grate moving velocity in an actual incinerator was also evaluated by applying the new code. 3d-MSW could present the influence of the grate moving velocity on gas temperature and carbon monoxide concentration. 3d-MSW is very useful as a simulation tool for understanding the phenomenon of the waste bed combustion in the stoker-type MSWI.
