하향식 고정층 폐기물 가스화기에 대한 CFD 해석

Waste-to-energy plants based on gasification using municipal solid waste (MSW) as their fuel are highly efficient rather than conventional sources of energy such as coal, oil or natural gas. This study proposes a Computational Fluid Dynamics (CFD) model of MSW gasification with air in a downdraft fixed bed gasifier. 3D commercial code ANSYS was used to predict the CFD analysis results of MSW gasification and to provide process fundamentals with regards to syngas production from MSW gasification. Values for temperature, velocity, and syngas species contours were obtained from the analysis and compared with experimental results. CFD predicted values compliment the trend obtained experimentally, indicating the accuracy of the analysis model followed.
