Patent ID: 7815129

Claim:
An apparatus for continuously delivering and non-intermittently introducing a liquid into a main compressor flow of a gas turbine, comprising: a supply line; a delivery line; a delivery device for delivering a mass flow of the liquid from the supply line to the delivery line; at least one atomizing element communicating with the delivery line; a branch line which branches off from the delivery line being arranged in the delivery direction downstream of the delivery device and upstream of the atomizing element; at least one changeover and/or regulating member for shutting off and/or throttling the branch line being arranged in combination with the branch line; a pressure measuring point being arranged in the delivery line; a first pressure regulator connected to the measured pressure, filtered via a high-pass filter for the selection of high-frequency changes of pressure, as a controlled variable and to the position of a regulating member, arranged in the branch line, as a manipulated variable to compensate for high-frequency changes of pressure; and a second pressure controller connected to the measured pressure, filtered via a low-pass filter for the selection of low-frequency changes of pressure, as a controlled variable to compensate for low frequency pressure fluctuations and to the position of an output controller of the delivery device.
