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

FIELD: power engineering.

SUBSTANCE: invention relates to the field of power engineering, specifically to 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 system comprises a liquid fuel supply line 1 to the gas turbine combustion chamber burners, a liquid fuel return line 2 from the gas turbine combustion chamber burners. The liquid fuel supply line 1 contains in series, one after the other, a dual liquid fuel filter 3, membrane tanks 7, a liquid fuel pump 4, a liquid fuel recirculation valve 17, an emergency shut-off valve 5, a control valve 6. On the liquid fuel return line 2, in series an emergency shut-off valve 8 and a control valve 9 are installed one after another. The liquid fuel supply line 1 is connected to the liquid fuel return line 2 through the liquid fuel recirculation line 26, which includes a resistance regulator 25, which is connected at one end to the recirculation valve 17, and at the other the end is cut into the pipeline of the return line of liquid fuel 2.

EFFECT: increasing the operational reliability of the liquid fuel supply system while simplifying its design and control algorithm, as well as reducing the cost of its manufacture.
