METHOD OF CLEANING OF FUEL MANIFOLD WITH INJECTORS OF COMBUSTION CHAMBER OF GAS-TURBINE ENGINE OF FUEL COKING PRODUCTS Russian patent published in 2015 - IPC F02C7/22 F23D11/38 F23D14/50 

FIELD: machine building.

SUBSTANCE: invention relates to the machine building, in particular to the methods of cleaning of fuel manifold with injectors of the combustion chamber of the gas-turbine engine off the fuel coking products. The method of cleaning of fuel manifold with injectors of the combustion chamber of the gas-turbine engine off the fuel coking products includes cleaning of the manifold with injectors for heated chemical injection, and monitoring of the degree of cleaning of the injectors with difference that the chemical is injected under the supercritical state at temperature and pressure not exceeding the permitted temperatures and pressures on the condition of the manifold strength, and degree of cleanness of the injectors is checked by the chemical flowrate through the manifold that achieves permanent rated value. The manifold with the injectors is cleaned as part of the engine. Organic or inorganic substance is supplied as the chemical.

EFFECT: invention ensures cleaning of the manifolds to the set technical characteristics which parameters are determined at the testing equipment by the pumping through of the fuel, the used reagents are nontoxic and inert in relation to the manifold materials, the method ensures ecological cleanness and low price, does not require expensive preparatory operations.
