Abstract
NO.sub.x abatement results with EGR obtained in practice have been drastically less than those predicted by kinetic calculations. This disparity can be eliminated in all heterogeneous combustion processes by complete mixing to the microscale of exhaust gas recirculation with intake air prior to introduction into the heterogeneous burner. To achieve the required mixedness the air and EGR must be folded together in a controlled fashion in a turbulent flow having mean flow streamlines structured so that turbulent diffusion and molecular diffusion need only act to mix at relatively small distances. Scaleable vortex mixing means to achieve this folding together and mixing are disclosed. Complete vortex mixing of air and EGR prior to the supply of this 'oxidizer mix' into heterogeneous combustion systems such as diesel engines, stationary turbines, large burners, and power plants produces radical NO.sub.x reductions at low cost.
