System for injecting of fluid into working medium of gas turbine has dual nozzle for two media connected to water pipe and combustion gas pipe and opening into intake section for working medium before or at compressor

摘要

The system for the injecting of a fluid into a working medium (5) of a gas turbine installation with a compressor (17) comprises a combustion gas branch pipe (31), a water pipe (35), and a dual nozzle (39) for two media connected to the water pipe and combustion gas pipe. The dual nozzle opens into the intake section (9) for the working medium before or at the compressor. The system has a nozzle assembly with at least one dual nozzle for two media and is installed in the intake duct (13) of an intake section. Independent claims are also included for the following: (A) a compressor with the proposed injection system; (B) a gas turbine installation with a compressor; and (C) a method for the injecting of a fluid into the working medium of a gas turbine installation with a compressor.
