DUAL-NOZZLE LANCE INJECTOR FOR GAS TURBINE, GAS TURBINE PLANT AND METHOD OF SUPPLYING GAS TURBINE Russian patent published in 2018 - IPC F23D11/38 F23R3/28 

FIELD: fuel combustion methods and devices.

SUBSTANCE: invention relates to a dual-nozzle lance injector for injecting fuel oil into a gas turbine combustion chamber, a gas turbine installation and a method for feeding a gas turbine. Lance injector for injecting fuel oil into the combustion chamber of a gas turbine includes: a tubular casing, extending along a main axis; a first inner supply conduit housed in the casing and coupled, at a respective supply end, to a first supply inlet; first nozzle (40), at a respective injection end of the first inner supply conduit; a second inner supply conduit housed in the casing and coupled, at a respective supply end, to a second supply inlet, accessible from the outside independently of the first supply inlet; and second nozzle (41), at a respective injection end of the second inner supply conduit.

EFFECT: invention simplifies the design, and also provides a common range of flow rates, wide enough to meet all load conditions.
