Patent number: 10794589Abstract: A liquid fuel cartridge for a gas turbine fuel nozzle includes a tube having an inlet end and an outlet end with one or more fuel exit orifices; and a homogenizer located within the tube, adjacent and up-stream of the outlet end. The homogenizer is formed by a substantially-cylindrical body open at opposite ends, and a first row of circumferentially-spaced flanges projecting radially outwardly from the substantially cylindrical body, with radially-outer edges of said flanges engaged with an interior surface of the tube thereby creating a plurality of apertures for a liquid fuel and water emulsion. The homogenizer body may also be provided with a plurality of circumferentially-spaced radially-oriented orifices to promote better mixing of the fuel/water emulsion.Type: GrantFiled: November 8, 2013Date of Patent: October 6, 2020Assignee: General Electric CompanyInventors: Borys Borysovich Shershnyov, Alexey Yurievich Gerasimov

Patent number: 10731862Abstract: A fuel nozzle assembly for a gas turbine engine is disclosed herein. The fuel nozzle assembly may include a premixing chamber formed between an outer annular shroud and an inner annular hub, a number of swirler vanes disposed about the premixing chamber between the outer annular shroud and the inner annular hub, one or more liquid fuel injectors positioned about the swirler vanes, and a flow of liquid fuel in communication with the one or more liquid fuel injectors.Type: GrantFiled: August 26, 2015Date of Patent: August 4, 2020Assignee: General Electric CompanyInventors: Borys Borysovych Shershnyov, Geoffrey David Myers, Alexey Yurievich Gerasimov, Natalya Igorevna Vyazemskaya

Patent number: 10570821Abstract: A pre-film liquid fuel cartridge includes a main body having a water passage, a liquid fuel passage, a compressed air passage and a pre-film tip disposed at a downstream portion of the pre-film liquid fuel cartridge. The pre-film tip includes a forward end portion that is axially separated from an aft end portion and an inner side that extends therebetween. The inner side at least partially defines a pre-filming surface which terminates at an emulsion atomizing shear edge. The pre-film tip includes a plurality of water injection ports oriented tangentially through the pre-filming surface, a plurality of liquid fuel injection ports oriented tangentially through the pre-filming surface and a plurality of atomizing air injection ports axially oriented around the emulsion atomizing shear edge. An atomizing air shear edge is defined downstream from the emulsion atomizing shear edge and the atomizing air injection ports.Type: GrantFiled: April 4, 2014Date of Patent: February 25, 2020Assignee: GENERAL ELECTRIC COMPANYInventors: Borys Borysovych Shershnyov, Alexey Yurievich Gerasimov

Patent number: 10508812Abstract: A pre-film liquid fuel cartridge (20) includes a primary liquid fuel passage (106), a plurality of inner fuel ports (116) and a plurality of outer fuel ports (124) that are in fluid communication with the primary liquid fuel passage. An inner pre-filming surface (142) is defined downstream from the plurality of inner fuel ports. The inner pre-filming surface (142) terminates at a first shear edge (140). An outer pre-filming surface (152) is defined downstream from the plurality of outer fuel ports. The outer pre-filming surface (152) terminates at a second shear edge (154). The first and second shear edges are relatively oriented so that a first pre-filmed liquid fuel sheet exiting the first shear edge intersects with a second pre-filmed liquid fuel sheet exiting the second shear edge, thereby atomizing the first and second pre-filmed liquid fuel sheets.Type: GrantFiled: May 12, 2014Date of Patent: December 17, 2019Assignee: General Electric CompanyInventors: Geoffrey David Myers, Borys Borysovych Shershnyov, Alexey Yurievich Gerasimov
