COMBUSTION DEVICE OF A GAS TURBINE POWER UNIT Russian patent published in 2021 - IPC F23R3/28 

FIELD: gas-turbine equipment.

SUBSTANCE: invention relates to the combustion device of a gas turbine plant. The combustion device includes: a heat pipe forming a combustion chamber, a variety of fuel injectors, a fuel collector to which the variety of fuel injectors are connected, and a fuel supply channel connected to a fuel collector, while the fuel collector includes a first chamber to which the fuel supply channel is connected, and a second chamber to which a variety of fuel injectors are connected. The outlet of the fuel supply channel is open to the first chamber, and at least one communication port connected with the first chamber is open to the second chamber. The outlet of the fuel supply channel faces the inner surface of the wall of the first chamber. The second chamber includes an area extending from the connection hole in the direction of the combustion chamber, and the inlets of the fuel injectors are located closer to the combustion chamber than the entire connection hole.

EFFECT: invention makes it possible to eliminate deviation in the amount of the fuel injected between multiple fuel injectors connected with a single fuel collector, and to reduce the amount of NOx formation.
