Abstract
A burner apparatus which comprises a pilot burner including a nozzle and swirlers disposed around the nozzle, and a plurality of main burners which are arranged around the pilot burner and each of which comprises a nozzle and swirlers disposed around the nozzle; and the angle of the swirlers for the pilot burner is set larger than the angle of the swirlers for the main burner so that the angles of the two types of swirlers cross. NOx production can be considerably reduced with a very simple structure based on the present invention for combustion in boilers and gas turbines.
