Abstract
1,274,370. Spray nozzle for turbines. MOTO. RENUND TURBINEN-UNION MUNCHEN G.m.b.H. 8 July, 1970 [9 July, 1969], No. 33227/70. Heading, F4T. A fuel nozzle 4, comprises cylindrical housing 10 and piston-type insert 11, for delivering a fuel/air mixture to a gas turbine engine and has a plurality of fuel delivery ports and a plurality of air intake ports such that when the nozzle 4 is mounted in a gas turbine engine upstream of an upstream flame tube wall 3, fuel jets emitted from the delivery ports entrain compressor air to cause it to be injected through the intake ports and preliminarily mixed with the jets before passing through transfer ports (17) to swirl chamber 18. Air flows in the directions indicated by arrows F, G, H, K, L, M, O to supply air for combustion and for cooling flame tube 2. Fuel, under pressure, is supplied through line 12 via metering orifices (13) (Figs. 5 and 6, not shown) in insert 11 into annular compartment 15, entraining air via. holes 16, the air/fuel mixture being subsequently forced through ports (17) (Figs. 5. and 6, not shown), circumferentially displaced and inclined with respect to orifices (13), and into swirl chamber 18 where the air and fuel are. thoroughly mixed and to which additional air is supplied' through tangential holes (19). A spray cone 21 may protrude from chamber 18 intoorifice. 22 to effect uniform fuel atomization and distribution, and a central fuel hole or holes 25 may supply additional fuel to chamber 18.
