EVALUATION OF COMBUSTION CHAMBER DESIGN USING CFD

Abstract

This paper compares two designs of a gasification chamber for combustion of biomass from the view of combustion quality and the resulting gaseous emissions. To explain the difference in the emission values of the two different designs computational modeling is used to visualize basic processes important for combustion taking place in the combustion chamber, notably velocity field, temperature field and mass fractions of combustion air in assumed gasification products. Due to high computational demand, the model is heavily simplified, notably by the absence of chemical reactions between air and gasification products but is accurate enough for this study.
