PROBLEM TO BE SOLVED: To provide a triple-counter-rotating swirler for flexible fuel and usage of it. SOLUTION: A flexible fuel fuel-air mixer includes an annular shroud, a center body, an inner swirler disposed around an outer surface of the center body, a low-energy-content fuel plenum having an annulus formed by inner and outer shrouds forming a gap between them, a fuel inlet, and a fuel plenum swirler disposed in the gap, an outer swirler having an inner circumferential end portion disposed around the outer shroud of the fuel plenum, and a high-energy-content fuel shroud disposed at the upstream end portion of the annular shroud outwardly from the outer swirler in the radial direction and circumferentially around the annular shroud. The high-energy content fuel shroud is in flow communication with the outer swirler. COPYRIGHT: (C)2008,JPO&INPIT
