Abstract:
A method of combusting a first fluid and a second fluid comprising the steps of:directing the first fluid in a central coaxial flow generally perpendicularly through a first fluid passage that extends through an injector faceplate, and into a combustion chamber;shrouding a length of the central coaxial flow adjacent to the injector faceplate with an outer coaxial flow, the shroud being formed by directing a portion of the second fluid through an annular/conical passage in the injector faceplate that surrounds the first fluid passage, the annular/conical passage being arranged such that the outer coaxial flow is directed radially inward and impinges on the central coaxial flow a distance after the central coaxial flow has exited the first fluid passage and after the outer coaxial flow has exited the annular/conical passage.
