Abstract
A blade carrier for an axial-flow compressor is provided with cooling passages, through which a cooling medium flows in a closed circuit. The cooling passages run at least approximately in the peripheral direction inside the blade carrier and are located in a closed water circuit which essentially comprises a circulating pump (31), a pressure-keeping vessel (32) and a heat exchanger (35). The cooling passages are arranged in a ring shape, each cooling ring (27) being provided with a feed line (28) and a discharge line (29). At least every second successive cooling ring is attached to a separate cooling path in the longitudinal direction of the blade carrier.
