This study aims to investigate how the position of secondary air affects incineration performance and pollutant emissions.
Computational Fluid Dynamics modeling using ANSYS FLUENT 2021 R1
Three configurations of secondary air inlets were tested
Solid waste modeled as porous medium
Comparative analysis using contour plots to visualize results
CO emissions reduced by 92.5%
NO concentration reduced by 90% and 95% in different cases
Optimized configuration increases calorific value while reducing pollutant emissions
