Gas Turbine Hot Corrosion: Causes, Effects, and Preventive Measures (June 2023)Hot corrosion is a source of nonrecoverable degradation in gas turbines. It is a chemical reaction among salts, sulfur, and heat, where the damages can reduce an engine’s life by up to 75%. One of the most effective methods is to eliminate the contaminants triggering the chemical reaction. This paper examines the causes of hot corrosion and assesses various methods of mitigation.

High Speed BalancingIndustrial compressors are run at incredibly high speeds under immense pressure every day. This stress causes the rotors inside to naturally warp and bend, creating imbalances over time due to their dynamic nature. If these imbalances go unchecked for too long they can lead to more catastrophic damage, expensive field repairs, and unplanned downtime costs surpassing $2MM per day. Consequently, there are long-standing and recommended balancing practices in place to prevent these problems.
