The invention relates to a burner for a gas turbine (10), wherein the burner (30) comprises a combustion chamber (28), a preheating device adapted to preheat air before it enters the combustion chamber (28) and a swirler (107) adapted to guide a swirler air flow (125) that comprises the preheated air to the combustion chamber (28), wherein the swirler (107) comprises a base plate (116) with a surface that confines the swirler air flow (125), wherein the surface has a hole (103) adapted to inject a liquid fuel into the swirler air flow (125) and the base plate has a channel (131 to 134) for transporting the liquid fuel to the hole (103), wherein at least a part of the channel (131 to 134) is oriented essentially parallel to the surface so that the liquid fuel can stream essentially parallel to the surface and can be preheated by the swirler air flow (125). |
