TWO-CIRCUIT INJECTOR FOR A TURBINE ENGINE COMBUSTION CHAMBER

摘要

A start-up injector for a turbine engine combustion chamber, said injector including a fuel injection circuit; and a fuel ignition circuit including a fuel injector supplied by the fuel injection circuit and a spark plug for igniting the injected fuel. The start-up injector also includes a partitioned enclosure including a first compartment in which the fuel is ignited by the spark plug and a second compartment separated from the first compartment by a thermally conductive partition; and a main combustion start-up circuit which includes at least one fuel injector supplied by the fuel injection circuit and opens into the second compartment of the enclosure such as to inject the fuel against the wall.

1. A start-up injector for a turbine engine combustion chamber, intended to be arranged on a combustion chamber wall and terminate in the latter via an orifice of the wall, the start-up injector comprising:
a fuel injection circuit, a fuel ignition circuit comprising a fuel injector fed by the fuel injection circuit, and a spark plug of the injected fuel, the start-up injector further comprising:
a partitioned enclosure comprising a first compartment wherein the ignition of the fuel by the spark plug takes place, and a second compartment separated from the first by a thermally conductive partition, anda principal start-up combustion circuit, comprising at least one fuel injector fed by said fuel injection circuit, and terminating in the second compartment of the enclosure by being arranged so as to inject fuel against said wall.
