Patent number: 8066471Abstract: Disclosed is an annular flow duct for a turbomachine, the flow duct arranged concentrically about a machine axis running in the axial direction and defined by a boundary wall of circular cross section for directing a main flow, wherein the boundary wall has a plurality of return flow passages distributed over its circumference and through which in each case a partial flow is detached from the main flow at a bleed position and returned to the main flow at a feed position situated upstream of the bleed position, and having aerofoils, arranged radically in the flow duct, of a blade ring, the aerofoil tips of which lie opposite the boundary wall, with a gap formed in each case, wherein the aerofoils are movable in a predetermined rotation direction along the circumference of the boundary wall. Furthermore, a compressor which is insensitive to pumping and flow separations, as viewed in rotation direction, the bleed position of each return flow passage lies upstream of the corresponding feed position.Type: GrantFiled: May 29, 2007Date of Patent: November 29, 2011Assignee: Siemens AktiengesellschaftInventors: Romain Bayere, Malte Blomeyer, Christian Cornelius, Torsten Matthias, Uwe Sieber

Publication number: 20100186417Abstract: A method for protecting a burner from being heated excessively during the combustion of a fuel in a combustion chamber is provided. The fuel is injected through a fuel nozzle at the same time as an inert gas in the surroundings of the injected fuel is injected into the combustion chamber in such a manner that the fuel is separated spatially from an oxidizer by the inert gas until an ignitable mixture of the fuel is produced.Type: ApplicationFiled: July 3, 2008Publication date: July 29, 2010Inventors: Malte Blomeyer, Olga Deiss, Andre Kluge, Thomas Kunadt, Berthold Köstlin, Martin Lenze, Paul Pixner, Uwe Sieber

Patent number: 7753677Abstract: Burners in prior art exhibit combustion instabilities in certain ranges. The operating range of burners is restricted by said instabilities. In an inventive burner, the combustible has a concentration distribution, whereby the concentration of the combustible reduces in a radial direction from the interior to the exterior.Type: GrantFiled: August 20, 2003Date of Patent: July 13, 2010Assignee: Siemens AktiengesellschaftInventors: Peter Berenbrink, Malte Blomeyer, Werner Krebs, Bernd Prade, Holger Streb

Patent number: 7654090Abstract: The invention relates to a burner having an annular premixing channel in which fuel can be discharged in a radially distributed manner. The radial distribution of the fuel can be regulated during operation of the burner in that fuel can be supplied, independently of one another, into a first and a second part of admission devices having admission holes varying radially in opposite direction by means of fuel supply lines. The invention also relates to a method for operating a gas turbine in which radial distribution of the fuel is regulated in a premixing channel of a burner.Type: GrantFiled: July 20, 2004Date of Patent: February 2, 2010Assignee: Siemens AktiengesellschaftInventor: Malte Blomeyer

Patent number: 7472540Abstract: The invention relates to a method for compensating variations in fuel composition in a gas turbine system consisting of at least two parallel-operated burner stages, wherein the fuel supply to at least two of the burner stages is adjusted in response to variations in fuel composition, wherein the fuel split between the burner stages, i.e. the relative increase in speed of the fuel supplied to the burner stages, is adjusted to a target value or maintained at a target value during adjustment of the fuel supply. The target value can, for example be a constant or a function of one or several variables. More particularly, the gas turbine system can comprise a pilot burner stage and a main burner stage. When the fuel supply is adjusted, the fuel split between the pilot burner stage and the main burner stage is adjusted to a target value or maintained at a target value.Type: GrantFiled: October 11, 2004Date of Patent: January 6, 2009Assignee: Siemens AktiengesellschaftInventors: Peter Berenbrink, Malte Blomeyer
