Method of controlling the injection of liquid into an inflow duct of a prime mover or driven machine

The injection of finely atomized liquid-droplets into the intake air flow of a compressor is used, for example, to improve the output of a gas turbine. If the atomization is effected via pressure atomizer nozzles, it is advantageous, when the injection device is operated with a portion of the design...

Zusammenfassung:	The injection of finely atomized liquid-droplets into the intake air flow of a compressor is used, for example, to improve the output of a gas turbine. If the atomization is effected via pressure atomizer nozzles, it is advantageous, when the injection device is operated with a portion of the design mass flow, to admit liquid to only some of the atomizer nozzles of the injection device. The atomizer nozzles may be arranged on nozzle tubes, liquid being jointly admitted to all the atomizer nozzles arranged on a respective nozzle tube, operated in such a way that the same mass flow is injected on each side of a symmetry line. To this end, nozzle tubes may be combined to form groups, to which liquid is jointly admitted, and the tubes of a group may be arranged in mirror image to one another relative to the symmetry line.
