Combustion in high-speed swirling flow is an alternate process to the high-intensity, low-weight combustion chamber for gas turbines. The increase in combustion intensity due to the centrifugal force field, the more-rapid dilution, and the greater stability of the cooling film on the outer wall, are the main advantages of this system. Further, the high air velocity may give a better pneumatic spray of kerosene injected in liquid phase. A test combustion chamber with premixed air and kerosene injected tangentially into an annular channel of outer diameter 100 mm and inner diameter 60 mm is used to check the validity of this concept. Velocities upstream of the flame, which was stabilized by means of a wedge-shaped flameholder, were of the order of 110 to 180 m/sec. Stability limits of the flame have been measured. They correspond to a fuel-air equivalence ratio of 0.65 for the lean limit, and 1.55 for the rich limit. Temperatures of 2300°K were obtained by means of a double-throat pneumatic pyrometer. Combustion is complete at a distance of 125 mm downstream from the flameholder.
