| Abstract: | In this paper, structures and characters of dual channel swirl burner with low NOx emission are theoretically analyzed, simulation experiments on air particle flow characteristic are implemented by means of cool model simulation technology. Distribution of the dense and dilute air stream along circumference in the outlet region of burner and the mechanism of the flame stabilizing ring are theoretically analyzed and experimentally researched. The mechanism of low NOx emission and flame stabilization at low load are preliminary find out in this paper. Figs 3 and refs 5. |
