Abstract
A method for using an injector to combust a first fluid and a second fluid comprises a directing the first fluid step and a shrouding step. The directing step comprises 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. In the shrouding step, a length of the central coaxial flow adjacent to the injector faceplate is shrouded with an outer coaxial flow. The shroud is 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 is 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. Transpiration of either of the fluids through the injector faceplate permits combustion a higher temperatures. The combustion at higher temperatures permits the use of precombusted first and/or second fluids. Further, the shroud may be discontinuous to enable inter injection combustion of shrouded fluid by the shrouded fluid passing through gaps in the shroud. Temperature of 1300 degrees Fahrenheit and higher may be obtained with the method.
