College of Environment al Science and Engineeri ng , South China Univers ity of Technol ogy Guangz hou 510006) Abstract Numerical simulation of combustion process in a MSW Incinerator of 750 t/ d is conducted using Computational Fluid Dynamics ( CFD) met od and t e effect of combustion process on t e control of dioxin and t e process of selective non- catalytic reduction is studied. T e average temperature and concentration of gas composition at t e furnace outlet is in a good consistent wit t e designed value, w ic indi cates t at calculation met od is valid. T e combustion of flue gas is completed, w ic could meet t e demands on t e control of dioxin. T e conditions in t e region around from 10 meters to 26meters of t e ex aust eat boiler couldmeet t e requirements on t e process of selective non- catalytic reduction.
