  "textContent": "The invention relates to a burner (1) for a gas turbine, comprising a pilot combustor (5), a supply module providing pilot fuel (20) and pilot air (21) into a pilot combustion room (23) being enclosed by a pilot burner housing (22) comprising a tapered exit throat (24) discharging a concentration of radicals and heat generated in a pilot combustion zone (25) into a main combustion room (15) enclosed by a burner housing (4). Further said burner (1) comprises an equalizer (6), which is provided with a plurality of holes through which a main flow of air (7) enters a cavity (8), wherein said burner further comprises a fuel injector (9) downstream the equalizer (6) to supply a main flow of fuel (12) into the main flow of air (7), wherein a burner axis (3) is defined by the center of the pilot combustion zone (23) and the center of the main combustion zone (14), wherein said burner further comprises a swirler (13) downstream the injector (9) to give a designated flow distribution to the flow of fuel (12) and air (7) entering downstream said main combustion room (15). To mainly reduce space requirement the equalizer (6) is built in such a manner that the main air (7) flow enters the cavity (8) in a basically radial direction with regard to the burner axis (3), wherein a channel leads from the equalizer (6) to the swirler (13) arranged circumferentially around the pilot burner housing (22), said channel and said swirler being built in such a way that the main air flow (7) from said equalizer is directed in a basically axial and circumferential direction.",
