Abstract
A multi-fuel combustion system for a turbine engine, the multi-fuel combustion system having a combustion chamber formed by a combustor liner. The combustion chamber defines a first combustion zone and a second combustion zone. A first fuel system is fluidly coupled with the first combustion zone, where a rotary fuel slinger provides a first fuel to the first combustion zone. A second fuel system is fluidly coupled with the second combustion zone, where a gaseous fuel injector provides a second fuel to the second combustion zone.
Claims18
A multi-fuel combustion system for a turbine engine, the multi-fuel combustion system comprising:
- a combustion chamber formed by a combustor liner, the combustion chamber defining a first combustion zone and a second combustion zone;
- a first fuel system fluidly coupled with the first combustion zone, wherein the first fuel system includes a rotary fuel slinger for providing a first fuel to the first combustion zone;
- and
- a second fuel system fluidly coupled with the second combustion zone, wherein the second fuel system includes a gaseous fuel injector for providing a second fuel to the second combustion zone, wherein the second fuel is a gaseous hydrogen fuel;
- a first ignitor extending through the combustor liner into the first combustion zone to ignite the first fuel;
- and
- a second ignitor extending through the combustor liner into the second combustion zone.
A slinger multi-fuel combustion system for a turbine engine comprising a compressor section, combustion section, and turbine section in a serial flow arrangement and a drive shaft coupled to one or more portions of the compressor section or the turbine section, the drive shaft defining an engine centerline, the slinger multi-fuel combustion system comprising:
- a combustion chamber having a radially-extending portion and an axially-extending portion;
- a liquid fuel injector having a slinger operably coupled to the drive shaft and having an outlet for emitting atomized liquid fuel into the radially-extending portion of the combustion chamber using centrifugal force from rotation of the drive shaft;
- a gaseous fuel injector having a gaseous fuel injector outlet for emitting gaseous hydrogen fuel into the combustion chamber downstream of the outlet of the liquid fuel injector such that combustion of the gaseous hydrogen fuel eliminates at least a portion of emissions from combustion of the atomized liquid fuel to reduce total emissions from the slinger multi-fuel combustion system;
- and
- a first ignitor and a second ignitor;
- wherein the combustion chamber is defined by a combustor liner;
- wherein the combustion chamber defines a first combustion zone and a second combustion zone downstream of the first combustion zone;
- wherein the liquid fuel injector is fluidly coupled with the first combustion zone;
- wherein the first ignitor extends through the combustor liner into the first combustion zone to ignite the atomized liquid fuel in the first combustion zone;
- wherein the gaseous fuel injector is fluidly coupled with the second combustion zone;
- wherein the second ignitor extends through the combustor liner into the second combustions zone to ignite the gaseous hydrogen fuel in the second combustion zone to eliminate at least the portion of the emissions from combustion of the atomized liquid fuel in the first combustion zone.
