Title:
MULTI-FUEL INJECTOR HAVING SEPERATE AIR - PREMIXING STRUCTURES FOR THE PLURALITY OF FUELS AND A CONSEQUENT COMMON MIXING STRUCTURE BEFORE THE NOZZLE OUTLET
Document Type and Number:
WIPO Patent Application WO/2012/090071
Kind Code:
A3
Abstract:
A system includes a turbine engine having a fuel injector (100). The fuel injector (100) includes fluid ducts (103,105,107), each having a fuel inlet (108,110,212) coupled to a distinct fuel source. The system includes a compressed air source that provides compressed air simultaneously to the fluid ducts (103,105,107), and a convergence point (106) where combined fuel and air streams from the ducts are mixed. The fuel inlets (108,110, 112) are in a parallel flow arrangement such that no fuel from one fuel inlet (108,110,212) is present at another fuel inlet (108,110,212)
