Reverse cleaning system of fuel gas nozzle and cleaning method of fuel gas nozzle

Abstract

The invention relates to a reverse cleaning system of a fuel gas nozzle and a reverse cleaning method of the fuel gas nozzle, and aims to mainly solve the problems, such as small flow caused by the phenomena such as channel scales, oxidation or blockage of the outlet multiple-small-hole structure of the fuel gas nozzle when the fuel gas nozzle has been used for a long time. A liquid outlet locatedat the side edge of the lower portion of a normal pressure container in a liquid storage assembly is connected to a liquid inlet of a circulating pump in a circulation assembly through a pipeline, one path of a liquid outlet of the circulating pump is connected to a liquid inlet located in the upper portion of the normal pressure container through a pipeline via a stop valve A, the other path ofthe liquid outlet of the circulating pump is connected with a liquid inlet located in the upper portion of a sealable pressure-bearing container in a cleaning assembly through a filter assembly, the fuel gas nozzle is arranged in the pressure-bearing container, a natural gas outlet on a natural gas nozzle penetrates through the pressure-bearing container through a pipeline to be connected to the liquid inlet located in the upper portion of the normal pressure container through a stop valve B. The system and the method is mainly applied to overhauling and adjusting of industrial fuel gas turbine combustion chamber nozzles, and can also be applied to overhauling and adjusting of parts with similar structures in other industries.

Description

technical field [0001] The invention relates to a gas nozzle reverse cleaning system and a gas nozzle reverse cleaning method, which belong to the field of thermal energy and power engineering and the field of cleaning devices. Background technique [0002] Regular repair and maintenance of industrial gas turbines, including condition inspection, performance testing, replacement, adjustment and maintenance of wearing parts such as compressors, combustion chambers, turbines and auxiliary systems at all levels, etc. The reverse cleaning system of gas nozzles is an industrial gas turbine combustion chamber One of the important tools for nozzle inspection and adjustment. The long-term use of gas nozzles has problems such as small flow rate caused by fouling, oxidation or blockage of the outlet multi-hole structure channel, which seriously affects the reliability of the combustion chamber operation and brings safety hazards to the operation of the gas turbine. At present, ultras...
