Original Abstract

This paper presents an experimental study of the effect of fuel-staging in combination with internal flue gas recirculation technology (FuGR) on NOx formation and flame characteristics. The experiments have been performed in a large-scale furnace fired by a natural gas swirl burner of industrial type. During the experiments five parameters have been varied following the plan designed with respect to Design of experiments (DOE) methodology. The parameters have included burner heat output, excess air ratio, position of secondary gas nozzles defined by their radial position and tangential orientation with respect to burner axis, and the diameter of primary gas throttle. The results show that the combination of gas staging together with FuGR indicates a marked decrease in NOx emissions.
