Patent number: 9278326Abstract: In certain embodiments, a feed injector system includes an inner channel configured to convey at least one of a solid fuel feed or a liquid reactant or moderator to a reaction zone. A first oxidizer channel extends around the inner channel, wherein the first oxidizer channel is configured to convey a first oxidizer stream to the reaction zone. A second oxidizer channel extends around the first oxidizer channel, wherein the second oxidizer channel is configured to convey a second oxidizer stream to the reaction zone. Additionally, a third channel extends around the inner channel and the first and second oxidizer channels, wherein the third channel is configured to convey at least one of the solid fuel feed or the liquid reactant or moderator to the reaction zone.Type: GrantFiled: June 27, 2014Date of Patent: March 8, 2016Assignee: General Electric CompanyInventor: Ali Ergut

Patent number: 9228744Abstract: A system includes a gasification fuel injector. The gasification fuel injector includes a mixing device configured to mix together at least two of a solid stream, a liquid stream, or a gaseous stream, or a combination thereof, to generate a mixture. The mixing device is disposed upstream of a tip portion of the gasification fuel injector, and the mixture is discharged from the tip portion.Type: GrantFiled: January 10, 2012Date of Patent: January 5, 2016Assignee: General Electric CompanyInventors: Ali Ergut, Shashishekara Sitharamarao Talya, Natesh Chandrashekar, Monty Lee Harned, Judith Pauline Oppenheim, Benjamin Campbell Steinhaus

Patent number: 9139788Abstract: A gasification system including a first feed line, a second feed line, a stabilization fuel line, and a fuel feed system controller including a processor. The processor is programmed to enable the stabilization fuel line to inject a stabilization fuel into a gasifier to initiate a stabilizer flame inside the gasifier, enable the first feed line to inject a dry fuel into the gasifier at a start-up dry fuel flow rate, increase the flow rate of the dry fuel from the start-up dry fuel flow rate to a normal operating condition (NOC) dry fuel flow rate, decrease a flow rate of the stabilization fuel as the flow rate of the dry fuel increases to the NOC dry fuel flow rate, and prevent the stabilization fuel line from injecting the stabilization fuel into the gasifier once the flow rate of the dry fuel is at the NOC dry fuel flow rate.Type: GrantFiled: August 6, 2010Date of Patent: September 22, 2015Assignee: General Electric CompanyInventors: Steven Craig Russell, Ali Ergut, Jamal Abdul Ferguson
