Abstract: Computational fluid dynamics(CFD) technology is used for optimal layout of over fire air(OFA) of large-scale municipal solid waste incinerator.The impact of different arrangements,spray angles of OFA nozzles and air ratios of two OFA layers on flue gas organization,turbulence,flue gas path length and residence time have been studied.The simulation result shows that when dual-rotating arrangement of OFA is adopt,spray angles are α1=40° and α2=35°,and air ratio of two layers is 2.5∶1,it is conducive to flue gas organization,and to ensure the complex optimization of turbulence,flue gas path length and residence time.
