LIQUID FUEL SUPPLY DEVICE FOR A GAS TURBINE PLANT Russian patent published in 2023 - IPC F02C7/22 F02C9/26 F23R3/28 

FIELD: gas turbine construction.

SUBSTANCE: invention relates to the field of gas turbine construction, in particular, to a system for supplying liquid fuel to the burners of a combustion chamber and can be used as part of a dual-fuel gas turbine power plant. The liquid fuel supply device includes a fuel supply line 1, a filtration unit 9, a fuel pump 11, a fuel return line 2, a drainage line 17, a drainage tank 15, control and shut-off valves 12, 13, while the device is additionally equipped with a hydraulic damping unit for pressure peaks 10 in the fuel supply line 1, and the fuel return line 2 is connected to the fuel supply line 1 through the unloading line 3, which is equipped with a direct-acting bypass safety valve 14, and the said unloading line 3 includes an inlet pipeline 18 to the safety valve 14 with a diameter Din and an outlet pipeline from a safety valve 19, with a diameter Dout, in the ratio Din/Dout not more than 0.85, while the liquid fuel supply device is made in the form of a monoblock and installed on a frame formed by supporting metal structures in which the drainage tank 15 is mounted in such a way that supporting metal structures are at the same time the walls of the drainage basin ka, forming a common supporting surface for the equipment of the fuel supply device.

EFFECT: improvement of the operational characteristics of the liquid fuel supply device, expressed in the expansion of the operating temperature range, increase in operational reliability and ease of maintenance when performed in the form of a monoblock.
