TURBOMACHINE COMBUSTION SYSTEM COMPRISING IMPROVED FUEL SUPPLY CIRCUIT Russian patent published in 2018 - IPC F02C7/228 F02C9/34 F23R3/34 

FIELD: engines and pumps.

SUBSTANCE: turbomachine combustion system comprises a combustion chamber, at least one starting injector, which is adapted to initiate combustion in the chamber, a plurality of main injectors distributed at constant angular intervals around the circumference of the combustion chamber, adapted for supplying fuel to the combustion chamber when combustion is initiated, and a fuel supply circuit. Combustion chamber is delimited by two axisymmetric walls – an external wall and an internal wall, which are arranged one inside the other and are connected by an annular chamber end wall. Fuel supply circuit is designed to supply at least one starting injector continuously, so that said injector is supplied with fuel both during the initiation of combustion and when supplying the chamber after initiation of combustion. Each continuously supplied starting injector is oriented toward the chamber end wall and dimensioned to spread a jet of fuel with an angular solution in a first direction of 120° to 180°. Flow rate of fuel injected by the main injectors between which the starting injectors are positioned is reduced by comparison with the flow rate injected by the other main injectors. Each starting injector is located between two successive main injectors equidistant from them.

EFFECT: invention is aimed at simplifying the fuel supply circuit.
