Process for corrosion protection of turbine internal components

摘要

A method and system of applying a corrosion inhibitor to the interior component parts of a turbine to provide corrosion protection to the components is disclosed. The intake and exhaust openings in the turbine are sealed using plastic and/or metal covers to contain the corrosion inhibitor inside the turbine. An air horn connected to an outlet vent in one of the covers induces air into and from the turbine's interior. A fog of corrosion inhibitor is introduced into the turbine through at least one inlet vent in a different cover located diagonally at an opposite end of the turbine. A sprayer is used for introducing the corrosion inhibitor into the inlet vent while the air horn is operating so that the corrosion inhibitor is caused to be drawn into and through the interior of the turbine to coat the interior component parts of the turbine. The corrosion inhibitor is introduced into the inlet vent until the corrosion inhibitor coats all exposed surfaces of the components inside turbine. The selection of vents as inlet and outlet vents and the positioning of the air horn and sprayer are then altered to allow a reverse flow of the fog to again saturate the turbine internals with corrosion inhibitor. All openings in turbine are subsequently sealed to contain the corrosion inhibitor inside the turbine.
