Experimental and Numerical Study of a Two-Stage Swirl Burner

In this study, we developed the design process and optimization of structural parameters a new low-NOx burner based on combustion technology flame stabilization principle. Firstly, basis two-stage swirl burner, applied fuel-graded introduced central nozzle structure to explore influence law graded NOx emissions. Secondly, previously optimized structure, matching between first- second-stage cyclone blades is analyzed obtain optimum solution for heat exchange efficiency front length. Finally, conical blunt in conjunction with principle, discuss effects different half cone angles stabilization, length, burner. The research paper provides reliable direction burners.
