Latest Patents

Among her latest patents is a design for a combustor featuring fuel sweeping structures. This innovative combustor includes an end cover and at least one fuel nozzle that extends from the end cover, partially surrounded by a combustion liner. The design incorporates an outer sleeve that is spaced apart from the combustion liner, creating an annulus between them. Additionally, it features a fuel injection assembly that includes a fuel injector extending through the outer sleeve, the annulus, and the combustion liner to the secondary combustion zone. A fuel supply conduit is positioned outside the outer sleeve, extending to the fuel injector, and a shielding assembly is coupled to the outer sleeve, partially surrounding the fuel supply conduit. The combustor also includes at least one fuel sweep opening defined in the outer sleeve and located within the shielding assembly.

Another notable patent is for a cartridge tip designed for turbomachine combustors. This cartridge tip consists of a main body with an outer annular wall and an inner core, each extending between respective upstream and downstream ends. The inner core is radially spaced apart from the outer annular wall, defining an annular air passage. The design includes a pilot fuel circuit that extends between a pilot inlet at the upstream end of the inner core and a pilot outlet at the downstream end. A main fuel circuit also extends between a main inlet in the upstream end of the inner core and multiple main outlets that are circumferentially spaced apart and located upstream from the pilot outlet.
