Patent ID: 8387394

Claim:
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, wherein the inflow guide means connects the burner casing running around the plurality of main swirl generators to the plurality of main swirl generators, 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, wherein the flow guide surface is curved so that it is aligned radially with and in the area of the burner casing and is aligned essentially axially at the inflow opening so that it is essentially parallel with the plain swirl generator pipe.
