FUEL NOZZLES UNIT AND UNIT OF COMBUSTION CHAMBER Russian patent published in 2016 - IPC F23R3/28 F23R3/04 

FIELD: engines.

SUBSTANCE: fuel nozzles unit, used in turbine engine comprises set of fuel nozzles. Group of fuel nozzles is located inside air pressure chamber confined by housing. Each of above fuel nozzles is connected to flame tube, restricting combustion chamber, and includes housing, mixing tubes, and at least one heat-removing pipeline. Housing has inner surface limiting cooling fluid medium pressure chamber and fuel pressure chamber. Mixing tubes pass through housing, and each has inner surface limiting flow channel passing between air pressure chamber and combustion chamber. At least one of mixing tubes has at least one cooling fluid medium opening, intended for cooling fluid medium flow discharge from cooling fluid medium chamber to said flow channel. At least one heat-removing pipeline communicates with cooling fluid medium pressure chamber in flow manner for supply of cooling fluid medium flow into it.

EFFECT: invention is aimed at flame stabilization, improvement of exhaust gases emission characteristics, combustion chamber nozzles unit longer service life.
