Systems and Methods for Late Lean Injection Premixing

摘要

A late lean injection combustor assembly may include a first interior in which a first fuel supplied thereto is combustible, a flow sleeve annulus including a second interior in which a second fuel supplied thereto is combustible, at least one fuel injector disposed about the second interior, and at least one elongate premixing conduit disposed about the flow sleeve annulus and in fluid communication with the at least one fuel injector. The at least one elongate premixing conduit may be in fluid communication with a compressor discharge air and the second fuel such that the compressor discharge air and the second fuel are premixed within the elongate premixing conduit before entering the second interior by way of the at least one fuel injector.

1. A late lean injection combustor assembly including a first fuel, a second fuel, and compressor discharge air, the late lean injection combustor assembly comprising:
a first interior in which the first fuel supplied thereto is combustible; a flow sleeve annulus comprising a second interior in which the second fuel supplied thereto is combustible, the flow sleeve annulus fluidly coupling the first interior and the second interior; at least one fuel injector disposed about the second interior, the at least one fuel injector configured to supply the second fuel to the second interior; at least one elongate premixing conduit disposed about the flow sleeve annulus and in fluid communication with the at least one fuel injector; and the at least one elongate premixing conduit being in fluid communication with the compressor discharge air and the second fuel such that the compressor discharge air and the second fuel are premixed within the elongate premixing conduit before entering the second interior by way of the at least one fuel injector.
