Abstract

The present invention proposes a technique that provides cooling flow to exhaust frame in a gas turbine. The technique includes a radial fan system arrangement to provide cooling flow to the exhaust frame cooling. The radial fan provides required flow and pressure head for purging. A rotor shaft extends out from a bearing and mounts on the radial fan through a bolt. A baffle arrangement is utilized to direct flow towards a bearing side.
