Abstract
An embodiment of the present invention provides a method and system of operating a combustion system that has Lean direct injection (LDI) functionality. The method and system provides a passive cooling system for an injector of the LDI system. The method and system may also provide a means to direct the flow of the fluid exiting the injector of the LDI system.
Claims20
A method of reducing a level of emissions generated by a system, the method comprising:
- providing a combustion system for generating power, wherein the combustion system comprises:
- a primary combustion system comprising at least one primary fuel nozzle that generates a stream of combustion products;
- a secondary combustion system located downstream of the primary combustion system;
- wherein the secondary combustion system comprises at least one injector for delivering a fluid into the stream of combustion products;
- providing an airstream, wherein the airstream supplies air to the primary combustion system and the secondary combustion system;
- apportioning the fuel between the primary combustion system and the secondary combustion system.
