Abstract
A method of operating a delivery apparatus and a delivery apparatus are disclosed for the continuous delivery of a liquid. The method and the apparatus are suitable in particular for use in a water injection system for injecting water into a main flow of a gas turbine. The delivery apparatus includes a plurality of delivery devices connected parallel to one another. In a first method step, the delivery devices of the delivery apparatus are assigned to at least two delivery device groups. The delivery device groups with the respectively assigned delivery devices are then switched to the active state from the rest mode in a rolling manner in time segments in order to deliver the liquid mass flow. In each case at least one delivery device is therefore operated in the rest mode in a rolling sequence per time segment.
