Publication number: 20240113319Abstract: A method includes providing steam to the solid oxide fuel cell stack, splitting exhaust gas from the cell stack into two portions, a first portion directed to a superheater and a second portion directed to an ejector and to a hydrogen separator. At least part of the first portion of the exhaust gas that is directed to the superheater is subsequently boiled in a boiler and then returned to the superheater. After being returned to the superheater, this part is directed to the ejector as high pressure steam so as to drive the ejector.Type: ApplicationFiled: September 29, 2023Publication date: April 4, 2024Inventors: John Robert PENDRAY, Achyut PAUDEL, Lars Krister HENRICHSEN, Enrique GARCIA-TORRESOLA, Jinyong LUO

Publication number: 20230261215Abstract: A method and system for recirculating an anode off gas in a fuel cell assembly includes receiving anode off gas and generating steam therefrom. A first flow of the steam is directed to a first control valve and a second flow of the steam is directed to a second control valve. The first and second control valves control steam that flows through the superheater and connects to a first ejector and a second ejector. In response to an operating parameter being equal to a threshold value, the first control valve is opened to allow the steam to pass through the superheater and subsequently at least partially drive the first ejector.Type: ApplicationFiled: February 11, 2022Publication date: August 17, 2023Inventors: John Robert PENDRAY, Charles J. VESELY, Scott Patrick BEARD

Patent number: 9709005Abstract: An apparatus comprises an internal combustion engine including an intake stream, at least one piston cylinder. An air assisted injector is configured to insert a plurality of liquid droplets into the intake stream or cylinder. The injector comprises a gas injection portion configured to deliver a gas to a mixing chamber at a first pressure and a first pulse width. A liquid injection portion is configured to deliver a liquid to the mixing chamber at a first temperature and a second pulse width, and after a predetermined delay relative to the gas so as to generate the plurality of liquid droplets having a mean diameter of up to 5 microns. A nozzle is configured to deliver the plurality of liquid droplets into the intake chamber or cylinder. The gas and the inserted liquid droplets are compressed during a compression stroke in the cylinder and fully vaporize throughout the compression stroke.Type: GrantFiled: February 18, 2015Date of Patent: July 18, 2017Assignee: CUMMINS POWER GENERATION IP, INC.Inventor: John Robert Pendray
