FOAMING PNEUMATIC POWER TYPE SYSTEM FOR INJECTING AIR/FUEL MIXTURE INTO TURBO-MACHINE COMBUSTION CHAMBER

PROBLEM TO BE SOLVED: To provide a pneumatic power type injection system capable of shortening time characteristic of spraying and vaporizing fuel over all operation speed of a turbo-machine. SOLUTION: This pneumatic power type injection system 2 for injecting air/fuel mixture into the turbo-machine combustion chamber is provided with a tubular structure 4 opened at an end 4b on the downstream side to carry air/fuel mixture and having an axis XX', at least one air supply channel 6 opened for the tubular structure 4 to introduce air into the tubular structure at pressure PA, an annular fuel passage 8 formed around the axis XX' in the tubular structure 4, connected with at least one fuel supply channel 10 in which fuel flows at pressure PC, and opened at an end 8b on the downstream side in the tubular structure 4, and a means for injecting gas into at least one fuel supply passage 10. Gas has a pressure PGbeing higher than PAand exceeding PCto cause foaming of fuel introduced into the structure. COPYRIGHT: (C)2006,JPO&NCIPI
