A method and a device for combusting gaseous fuel which contains hydrogen or consists of hydrogen, includes a burner which provides a swirl generator (1) into which liquid fuel is feedable centrally along a burner axis (A), forming a liquid fuel column which is conically formed and which is enveloped by, and mixed through with, a rotating combustion air flow which flows tangentially into the swirl generator (1). The gaseous fuel is fed inside the swirl generator (1) largely axially and/or coaxially to the burner axis (A), forming a fuel flow with a largely spatially defined flow pattern (9) which is maintained inside the burner and bursts open in the region of the burner outlet.

What is claimed is: 1. A method for combusting gaseous fuel, the method comprising:providing a gas turbine having a burner and a combustion chamber, the burner comprising a swirl generator and into which burner liquid fuel can be fed centrally along a burner axis, forming a conical liquid fuel column, and which liquid fuel column is enveloped by, and mixed through with, a rotating combustion air flow which flows tangentially into the swirl generator;feeding a gaseous fuel having a hydrogen portion of at least 50% inside the swirl generator at least one of axially and coaxially to the burner axis, forming a fuel flow with a spatially defined flow pattern which is maintained inside the burner;mixing the fuel flow thoroughly with combustion air to form an air-fuel mixture;bursting open the air-fuel mixture in the region of the burner outlet, including forming a backflow zone in the combustion chamber; andcompletely combusting the air-fuel mixture inside the combustion chamber while maintaining the backflow zone.
