Steam turbine users understand the steam turbine rotor is a critical component, and protecting it is key to successful operation. Rubs during startup between labyrinth shaft seals and the rotor present a number of issues. New seals typically rub during the first few starts, negating valuable maintenance dollars invested to restore seal clearances. Furthermore, shaft seal rubs can cause a bowed rotor, which damage the tight clearance of blade tip seals. In severe cases, the rotor is permanently damaged. Risks quickly turn into costly maintenance dollars as well as the financial impact associated with the decrease in turbine performance.
