Results of computational and experimental studies in support of the design of a low NO{sub x} oil burner are presented. Radial density stratification is utilized in the Radially Stratified Flame Core (RSFC) burner to reduce the air-fuel mixing in the flame`s near burner flow field and increase the fuel-rich zone residence time in order to reduce NO{sub x} emissions. In the course of the modeling, relationships were established between flow field and flame characteristics in search of an optimal flow pattern leading to low emissions without excessive flame length. The optimal flow pattern was dominated by two internal recirculating zones (IRZ), both produced by the rotating burner air flow. The key burner variables are the radial distributions of the axial and tangential components of the burner air velocity, the fuel spray angle and droplet size distribution. The trends of the modeling data are compared with those of experimental data obtained in full scale tests.
