Zusammenfassung:	Disclosed is a burner apparatus which comprises a pilot burner (11) comprising a nozzle (11a) and swirlers (11b) disposed around the nozzle, and a plurality of main burners (12) which are arranged around the pilot burner and each of which comprises a nozzle (12a) and swirlers (12b) disposed around the nozzle; and the angle ( theta ) of the swirlers for the pilot burner is set larger than the angle ( phi ) 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 combustors in boilers and gas turbines.
