Publication number: 20230151966Abstract: A burner component of a burner. The burner has a flow channel, in which combustion air flows in a flow direction from upstream to downstream. The burner component includes a wall portion, which adjoins the flow channel; a plurality of injection nozzles, which are arranged in the wall portion; and a plurality of vortex generators, which are arranged on the wall portion. The vortex generators have a concavely curved sloped surface rising in the flow direction to improve the distribution of the fuel in the combustion air.Type: ApplicationFiled: December 10, 2020Publication date: May 18, 2023Applicant: Siemens Energy Global GmbH & Co. KGInventors: Stefan Dederichs, Michael Huth, Ramsatish Kaluri, Udo Schmitz, Anatol Schulz, Daniel Vogtmann

Patent number: 11313562Abstract: A method for operating a burner arrangement of a heat engine, particularly a gas turbine, having a plurality of burners, each having at least one pilot burner and main burner, in which method, on the basis of a preset operation of the heat engine, the total quantity of fuel supplied to the burners is maintained substantially constant in a load-controlled manner: in a first group of burners, for each burner, both the pilot burner as well as the main burner are supplied with fuel; in a second group of burners, the fuel supply to the main burners is interrupted, while the pilot burners continue to be operated; and the fuel quantity remaining as a result of the interruption of the fuel supply to the main burners of the second group is redistributed to the still active main burners of the first group. CO emissions are reduced as a result.Type: GrantFiled: January 22, 2019Date of Patent: April 26, 2022Assignee: Siemens Energy Global GmbH & Co. KGInventors: Udo Schmitz, Carsten Seiler, Stefan Wyhnalek

Patent number: 9127842Abstract: A burner incorporating a pilot cone and a mounting insert is provided. The pilot cone is constructed as a pilot cone assembly which is decoupled from the mounting insert. Further, an operating method for increasing the service life of a burner which incorporates a pilot cone assembly and a mounting insert is provided. The pilot cone assembly has a cone side and incorporates at least one further side where the further side is arranged to be essentially parallel to one of the sides of the mounting insert and spaced apart from it, so that between the further side and the side of the mounting insert there is a defined gap. In an operation of the burner, the gap is significantly reduced by the thermal expansion in at least at one point of contact between the further side and the side of the mounting insert. Finally, an assembly method is provided.Type: GrantFiled: May 27, 2009Date of Patent: September 8, 2015Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Andreas Böttcher, Thomas Grieb, Matthias Hase, Peter Kaufmann, Werner Krebs, Tobias Krieger, Patrick Lapp, Mark F. Rubio, Udo Schmitz, Daniel Vogtmann, Ulrich Wörz

Patent number: 7080515Abstract: A gas turbine engine (120) includes a cylindrical basket (146) having an axis (14) and a single main burner assembly (12) disposed within the basket. A burner insert (34) is disposed in an annular space between the burner assembly and the basket. The insert includes a face perpendicular to the axis of the basket. A plurality of passageways (114) are formed in the basket, positioned proximate to and downstream of the burner insert for allowing passage of a portion of an oxidizer flow (42) into a combustion chamber (30). A fluid flow path (38), defined between a combustion chamber liner portion (32) of the basket and a casing (40) spaced radially outward from the combustion liner portion, discharges a fluid into a flow reversal region (118) proximate an inlet (20) of the burner assembly. A fuel outlet (44) is disposed in the flow reversal region.Type: GrantFiled: September 19, 2003Date of Patent: July 25, 2006Assignee: Siemens Westinghouse Power CorporationInventors: Samer P. Wasif, Udo Schmitz, Robert Bland, Karsten Jordan, John Carl Glessner, J. Scott Markovitz, Bernd Prade, David Kargetta, Stephen Ramier, Stefan Dahlk
