A stator vane for an industrial turbine, the vane includes a serpentine flow cooling circuit for cooling of the airfoil, and a separate purge air channel to supply purge air to the rim cavities. The purge channel is formed as a separate channel from the serpentine flow channels so that the purge air is not heated by the hot metal and has smooth surfaces so that pressure losses is minimal.
