Abstract: 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.

Abstract: An injector tip for a nozzle includes a center body having a plurality of center body openings at a distal end configured to inject a fuel flow into a combustion zone of a combustor. One or more fuel passages are arranged around the center body and are configured to inject a fuel slurry into the combustion zone. One or more oxygen passages are arranged around the center body and are configured to inject an oxygen flow into the combustion zone.

Abstract: A crossfire tube for attachment between casing bosses of combustors includes a bellows assembly having a bellows with opposite cylindrical ends welded to annular flanges. The annular flanges include a bolt circle for securing the flanges to the combustor bosses. The flanges bear against a gasket for sealing against inserts welded to the casing bosses for retrofit in the sealing assembly to combustors or to seats where the inserts and bosses are formed integrally during original equipment manufacture. A telescoping cylindrical sleeve surrounds the bellows to protect from falling foreign object damage.

Abstract: A low-emission method for producing power using a gas turbine includes premixing a plurality of fuel and air mixtures, injecting the fuel and air mixtures into a combustion chamber using a plurality of fuel nozzles, and adjusting a ratio of fuel and air injected by at least one of the nozzles to control a fuel/air concentration distribution within the combustion chamber.
