Abstract
A burner () for a combustion chamber of a gas turbine, especially in a power plant, includes an oxidizer feed device () for feeding a gaseous oxidizer into a mixer chamber () of the burner (), a gaseous fuel feed device () for feeding a gaseous fuel into the mixer chamber (), and a liquid fuel feed device () for feeding a liquid fuel into the mixer chamber (). In order to improve the operation of the burner () with liquid fuel, the liquid fuel feed device () has a main feed line () which feeds liquid fuel to a plurality of injection orifices (). Some of these injection orifices (), with regard to a main outflow direction () of the burner (), which has an oxidizer-fuel mixture, which flows from the mixer chamber (), at an outlet opening () of the mixer chamber (), are arranged in series. Some or all of these injection orifices () are designed so that a main injection direction () of the respective injection orifice () has a radial component which extends radially to the main outflow direction ().
