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.

A method of controlling the injection of liquid into an inflow duct of a prime mover or driven machine, the method comprising: providing an injection device for a total nominal mass flow, the injection device having a number of pressure atomizer nozzles that are arranged in a distributed manner substantially uniformly over a cross section of the inflow duct to provide sufficient pumping distance, each nozzle being configured for throughput of a partial mass flow of the total nominal mass flow, the injection device having at least one symmetry line defining two sides; at a least three sequential injection mass flows which are below the total nominal mass flow, for each injection mass flow, admitting liquid to only some of the nozzles, wherein on each side of the symmetry line, liquid is admitted to the nozzles so that in sum the partial mass flows of the nozzles to which liquid is admitted is the same on each side of the symmetry line in order to avoid asymmetry of thermodynamic states that would be damaging to a compressor downstream of the injection device and would reduce the pumping distance; wherein at least two nozzles are combined to form a nozzle group, liquid being jointly admitted to the nozzle group having an associated group throughput of liquid, and control being provided for selective admission of liquid to the nozzle group, such that flow of liquid to different nozzles of the injection device may simultaneously be controlled; wherein at least two atomizer nozzles are arranged on at least one nozzle tube, with liquid being jointly admitted to the nozzles arranged on each of said at least one nozzle tube; and wherein nozzle tubes arranged essentially symmetrically to the symmetry line are combined to form a group to which liquid is to be jointly admitted. 2. The method of claim 1, wherein on each side of the symmetry line, liquid is admitted to nozzles arranged essentially in mirror image to one another. 3. The method of claim 1, wherein the nozzles are combined to form nozzle groups such that the same partial mass flow is passed through in each group as group throughput. 4. The method of claim 1, wherein the nozzles are associated with tubes that are combined to form groups such that the same partial mass flow is passed through in each group as group throughput. 5. The method of claim 1, wherein the nozzles are combined to form groups so that at least a first of the groups has a first group throughput and at least a second of the groups has a second group throughput which is smaller than the first group throughput. 6. The method of claim 5, wherein the second group throughput is 50% of the first group throughput. 7.

The method of claim 9, wherein the group throughput of a group is in each case twice the group throughput of the next smaller group so that the groups have a binary graduation of the group throughputs. 11. The method of claim 1, wherein the nozzles are associated with tubes that are combined to form groups so that when liquid is admitted to the nozzles the group throughputs of the individual groups have a geometric graduation. 12. The method of claim 11, wherein the group throughput of a group is in each case twice the group throughput of the next smaller group so that the groups have a binary graduation of the group throughputs. 13. The method of claim 1, wherein at least two tubes are combined to form a group, liquid being jointly admitted to the tube group having an associated group throughput of liquid. 14.
