Abstract:
1. A gas-turbine burner, comprising: a plurality of main swirl generators, each main swirl generator featuring an inflow opening formed by a main swirl generator edge; and an inflow guide means having a flow guide surface running from one of the inflow openings to an adjacent inflow opening, the flow guide surface extends from and is adjoined by a plurality of main swirl generator edges forming the plurality of inflow openings and extends to a burner casing and radially widens out from the main swirl generator edge, wherein the plurality of main swirl generators are arranged central-symmetrically around a pilot burner, and wherein the flow guide surface runs radially outside the plurality of main swirl generators, and wherein the flow guide surface extends from a first section facing radially outwards to a second section facing radially inwards lying at the inflow opening, wherein the inflow guide means connects the burner casing running around the plurality of main swirl generators to the plurality of main swirl generators, and wherein the inflow guide means closes off a gap between the burner casing running around the plurality of main swirl generators and the plurality of main swirl generators by adjoining the burner casing on a first end and adjoining a main swirl tube on a second end.
