A combustion chamber for gas turbine engines, particularly aircraft turbojet engines, which is constituted of an outer casing, at least one flame tube inserted therein, and incorporating at least one ignition device for the produced, respectively, supplied fuel-air mixture. The ignition device comprises two high-capacity ignition or spark plugs which are presently arranged in series in a single axial plane in the flame tube, and further including an ignition fuel nozzle, whose fuel injection spray cone will simultaneously encompass the ignition spark zones of both high-capacity spark plugs.

Combustion chamber for gas turbine engines, particularly an ignition

A combustion chamber including an outer casing having a flame tube within it defining an annular space between them which receives air from the engine compressor. The flame tube has diametrically opposed pairs of air inlet ports through which air from the annular space flows substantially radially into the flame tube. A flow guide on the exterior of the flame tube is associated with each air inlet port. The upstream end of each flow guide is open to air from the compressor and the downstream end extends inwardly and downstream and partitions the upstream portion of its respective air inlet port from the annular space. A fuel tube extends into each flow guide. A curved baffle may extend radially inwardly at each air inlet port and define an arcuate louver between the baffle and the downstream edge of its respective air inlet port. Each air inlet port may have a square upstream portion merging into a circular downstream portion. A porous metering member may be provided in each fuel tube along with a flow restrictor.

Combustion chamber for gas turbine engines

A combustion engine for gas turbine engines, constituted of an outer housing and having at least one flame tube inserted therein which is suppliable with secondary or mixing air through the intermediary of an annular passageway formed between the outer housing and the flame tube while, on the other side, the primary zone within the flame tube has fuel-enriched combustion air conveyable thereto, and wherein there are provided at least two fuel atomizer nozzles which are controllable independently of each other.

A combustion chamber for gas turbine engines or power plants having devices for the gaseous processing of the fuel which is introduced therein, characterized by the combination of the following features:
