Publication number: 20230392783Abstract: A burner supply tube, and a burner arrangement having such a burner supply tube, which includes a tube wall extending having a tube diameter and at least one integrated fuel channel extending from a fuel input at an upstream tube end to a fuel output at a downstream tube end. To enable an integrated design, the fuel channel is along the majority of the tube length helical with a gradient of at least 0.5 times and at most 5 times the tube diameter.Type: ApplicationFiled: August 11, 2021Publication date: December 7, 2023Applicant: Siemens Energy Global GmbH & Co. KGInventors: Lennart Felix, Anders Haevaker, Olle Lindman, Jan-Erik Lundgren, Simon Svanström, Marcus Oscarsson

Patent number: 11371438Abstract: A cooled machine component having a body with at least one integrated cooling channel having a lattice structure for guiding a cooling fluid through an interior, the lattice structure arranged as a void space penetrated by a plurality of hollow or solid struts. The lattice structure has an inlet for providing the cooling fluid to be guided through the void space of the lattice structure, and has an outlet for receiving the cooling fluid, the outlet being fluidically connected to a hollow interior of at least one of the plurality of hollow struts. At least a subset of the hollow struts provides a fluidic connection for cooling fluid from the outlet to a plurality of further downstream discharge ports. Walls of the body surrounding each of the plurality of further downstream discharge ports are physically connected to corresponding jackets of the at least one of the plurality of hollow struts.Type: GrantFiled: September 26, 2017Date of Patent: June 28, 2022Assignee: SIEMENS ENERGY GLOBAL GMBH & CO. KGInventors: Jan-Erik Lundgren, Erik Munktell

Patent number: 11204166Abstract: A burner of a turbomachine, particularly a gas turbine engine, has at least one burner section having an annular wall surrounding a respective section of a burner interior, the annular wall including: an annular inner surface delimiting the burner interior, and a plurality of dampening cavities for the dampening of thermo-acoustic vibrations in the burner interior, each dampening cavity being connected to the annular inner surface through at least a dampening hole. A method of manufacturing such a burner includes additive manufacturing of the annular wall as an integrally formed component, or additive manufacturing of the upstream burner section, wherein the intermediate burner section and the downstream burner section as integrally formed component.Type: GrantFiled: June 29, 2018Date of Patent: December 21, 2021Assignee: Siemens Energy Global GmbH & Co.

Patent number: 11098896Abstract: A burner of a turbomachine has an upstream burner section providing a first fuel and an oxygen containing fluid to an upstream end of a burner interior, a downstream burner section for providing a second fuel to a downstream end of the burner interior, and an intermediate burner section between the two sections. The intermediate burner section has an annular wall surrounding a mid-section of the burner interior. The annular wall has an annular cooling fluid passage, for guiding the oxygen containing fluid, and an annular fuel passage for guiding the second fuel to the downstream burner section, the annular fuel passage being more distant to the burner interior than the annular cooling fluid passage. Two annular slots are incorporated into the annular wall. The upstream burner section has at least one integrated fuel tube through a body of the upstream burner section, configured to feed the annular fuel passage.Type: GrantFiled: August 18, 2017Date of Patent: August 24, 2021Assignee: Siemens Energy Global GmbH & Co.

Patent number: 10781696Abstract: A turbomachine component, gas turbine combustor component, or burner component, including a body with a first, second and third section, the sections being integrally formed with another and built from a same material, and an end face of the first section of the body. The end face, during operation, is exposed to a first temperature higher than a second temperature of a cooling fluid. The second section is located between the first and third section and is formed in parts as a lattice structure. The lattice structure has a plurality of rod-shaped struts, wherein each of a first set of the plurality of struts has a first end, the first end being connected to the first section, and a void penetrated by the plurality of struts, the void providing at least one fluid passage via which the cooling fluid is guidable through an interior of the second section during operation.Type: GrantFiled: July 29, 2016Date of Patent: September 22, 2020Assignee: Siemens AktiengesellschaftInventors: Jonas Eriksson, Andreas Graichen, Nicklas Johansson, Jenny Larfeldt, Jan-Erik Lundgren, Daniel Lörstad, Erik Munktell
