Zusammenfassung:A method of cooling a turbine having internal moving components to a predetermined temperature is disclosed. The method comprises taking the turbine offline. While the turbine is offline, nitrogen is flowed through the turbine until the turbine reaches the predetermined temperature while controlling the flow of nitrogen from at least one injection point to prevent damage to the moving components of the turbine by achieving uniform cooling of the internal moving components. Then the flow of nitrogen is stopped. A method and assembly for cleaning a turbine having a deposit formed on an internal surface of the turbine is also disclosed.
