Storage and management of standby rotors for catalytic gas turbines
Thread Content
For the company’s catalytic unit gas turbine, a set of spare rotors was purchased from the manufacturer; the replacement of the turbine rotor is carried out simultaneously during the major maintenance shutdown of the unit, with a maintenance cycle of 2 years. I would like to ask everyone: how do you handle the storage, inspection, and necessary maintenance of spare rotors over a period of 2 years? Thank you!
I think a dedicated protective case filled with nitrogen, that can be placed upright, would work
I don’t know much about it, so I’m here to learn a bit*. In my opinion: 1. It is necessary to keep the environment in which the rotor is stored clean to prevent corrosion over time; 2. Corrosion of the shaft should be avoided – it is recommended to store it vertically if possible, and if it is stored horizontally, regular rotation of the rotor is essential; 3. It is best to inspect the rotor ahead of its next use to ensure it is in good working condition.
