Studying the swirl air flow characteristics at the output of the model of pulverized-coal swirl burner
Investigation of dynamic characteristics of swirl air flow at the output of the experimental model of pulverized-coal swirl burner has been introduced. The intensity of mixing heated uniflow stream with swirl flow cold gas was determined. It was shown that at the ratio of air consumption through the ignition channel to the external swirl flow lower than 0,3 the area of reverse flows is direct at the output of the pulverized-coal swirl burner.
