ABSTRACT:
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. A blower connected to the turbine introduces air into the turbine's interior. A fog of corrosion inhibitor is added to the air and introduced into the turbine through at least one inlet vent in the turbine for introducing the air from the blower into the turbine's interior, and introducing the corrosion inhibitor into the inlet vent while the blower 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 step of introducing the corrosion inhibitor into the inlet vent is performed until the corrosion inhibitor appears at the outlet vent at the opposite end of the turbine from where the inlet vent is located or until the corrosion inhibitor coats all exposed surfaces of the components inside turbine. All openings in turbine are subsequently sealed to contain the corrosion inhibitor inside the turbine.
