Title: Improvements relating to combustion chambers for combustion turbines, jet propulsionengines and the like
IPC: F23R3/30
Filed: 1956-05-22
Abstract: 809,300. Generating combustion products under pressure. DAIMLER-BENZ A.G. May 22, 1956 [May 25, 1955], No. 15794/56. Class 51 (1). In a combustion chamber, for example of a gas turbine engine or a ram jet unit, a baffle plate 10 is disposed inside the chamber in the main flow of combustion air and is adapted to produce in that flow a toroidal eddy 12 in whose core portion the direction of flow is opposite to the general direction of the main flow through the chamber, a passage 11 being provided for forcing additional combustion air into the core portion of the eddy so as to increase the kinetic energy of the existing eddy. The opening 13 by which the additional air is discharged into the chamber is disposed upstream of the baffle plate, and the baffle plate extends radially outwardly beyond the opening. In Fig. 1 the main flow of combustion air enters the chamber through a volute 7 which imparts a swirling movement thereto as indicated by the arrow 9. Gases discharge from the chamber through the annular outlet 15 around the baffle plate 10. Fuel supplied through the pipe 16 issues through injector 17 into the additional air being supplied through the pipe 11 into the toroidal eddy. In Fig. 2 the blow pipe 21 for additional air passes from the inlet end of the combustion chamber to adjacent the baffle 10, the air discharging from the pipe being caused to flow in an upstream direction into the core of the toroidal eddy by means of the tubular portion 23 integral with the baffle plate. Fuel is supplied to the additional air through the pipe 26 as in the first embodiment. The additional air may be given a swirling motion by means of swirl vanes 27 disposed around the fuel pipe 26. In place of the volute 7 shown in Figs. 1 and 2, the main air supply may enter axially and flow between radially-disposed swirl vanes. In the ram-jet unit shown in Fig. 4, ram air enters through the inlet 34 and is caused to swirl by means of the swirl vanes 31. Additional air entering through the pipe 33 is caused to flow in an upstream direction by means of the guide device 35, 23 associated with the baffle plate 10. In Figs. 2 and 4, the fuel supplied through the pipes 26 is vaporized before discharge into the combustion space.
