Compressor, esp. for turbine group, pref. power stations has dispersion device with conical body in mouth section of blow-off channel, for dispersion of blow-off flow

摘要

The compressor has a blow-off channel (9) opening into an outlet duct (8) to introduce a blow-off flow (11). This is dispersed by a dispersion device (13) in a mouth section (12) of the channel. The device has a conical part, and this is positioned centrally or eccentrically in the mouth section, to project out of the channel and into the duct. The device also has a retainer bar. The conical part is hollow and has a conical wall with passage.
