Abstract

The EV burners with double cone are investigated numerically for NO _x reduction by evaluation of the mixing characteristics with the parameter of the modified unmixedness. In case 1, where fuel is injected from the top of the burner, unmixedness inside the burner has been reduced or improved. Experimental and numerical results showed N_x Oreduction by 13% and 5%, respectively. The reduction of the unmixedness resulted in decreased NO_x emission. These numerical results showed that NO_x reduction can be attained by mixing enhancement inside the burner.
