Abstract

Large-eddy simulation (LES) is applied to both a pulverized coal combustion and non-conbusion field in a combustion test furnace with a practical advanced low NOx burner called CI-α burner, and investigated the effect to coal combustion on flow field and ignition mechanism. The results show that predicted flow filed and coal particle behavior are in general agreement with the experiment. Coal combustion storongly affect flow filed. Primary air jet and swirling flow is enhanced by the burned gas expansion. Moreover, a recirculation flow formed by strong swirling flow is observed near the burner region and keeps satable coal combustion by transporting hot gas and increasing coal particle residence time.
