Abstract

911,759. Generating combustion products under pressure. GENERAL ELECTRIC CO. May 20, 1959 [June 2, 1958], No. 17110/59. Class 51 (1). In the combustion equipment shown in Fig. 1, which may be used in gas turbine, rocket and jet propulsion engines, a mixture of fuel and air or other atomizing fluid is injected through a nozzle 5 located on the axis of the flame tube 2 at the closed end 4 thereof. The vertex angle of the conical jet 7 is about 20 degrees, but may be up to 60 degrees. Primary air is introduced through an annular nozzle 9, a circumferential row of ports containing nozzle vanes 10a, 10b, and a circumferential row of flaring nozzles 11, the directions of the primary air jets being such that they assist the fuel jet 7 in producing a toroidal flow 8. The nozzles 11 may be replaced by circular holes, and the pairs of vanes 10a, 10b may each be replaced by a nozzle similar to 11. The toroidal flow 8 retains the particles of fuel (which may be Bunker C oil) in the primary zone for sufficient time to ensure ignition and initial combustion. Secondary air is admitted through ports 12, 13, 14, spaced from the end of the fuel nozzle 5 at respective distances of about ¥, 1“ and 1¥ times the diameter of the flame tube 2, the respective diameters of the ports being about <SP>1</SP>/ 20 , <SP>1</SP>/ 13 to <SP>1</SP>/ 16 and 1/ 10 times the diameter of the flame tube. Additional rows of secondary air ports may be provided. Louvres (not shown) are provided in the flame tube wall for admitting cooling and insulating air to its inner surface. In a modification, Fig. 4, the domed end 4 is replaced by a conical member 15 surrounded by a shroud comprising a cylindrical part 18 and a disc part 17. Primary air enters a chamber 19 through a circumferential row of metering ports 17a and then passes into the flame tube 2 through circumferential rows of plain ports 15a and louvred ports 15b, 15c. Primary air also enters the flame tube 2 directly through an annular nozzle 9c. As before, the directions of the primary air jets are such as to produce a toroidal flow 8. The nozzle 9c may be omitted, the cylindrical part 18 then being smaller in diameter than the flame tube 2 and projecting into it to afford a narrow annular nozzle through which cooling and insulating air enters along the inner surface of the flame tube.
