Why Rotor Blade Failures in Steam Turbines Demand Attention: A Data-Driven Perspective
Steam turbines are the workhorses of thermonuclear power plants and large ships, but their efficiency and safety hinge on one critical component: the rotor blade. Last-stage rotor blades (LSRBs) are prone to failure due to prolonged exposure to high-speed wet steam (HSWs). These failures aren’t just costly—they can lead to catastrophic accidents, with fractured blades causing cascading damage to other components running at high speeds.

Avoiding Bearing Failure Through Proper Grease Management
More than 60% of bearing failures are due to lubrication, and grease failures contribute more than the oil. Whenever the bearings are replaced in the housing, mostly the housing is fully packed with the grease without keeping empty space and started operating the bearing after the housing end cover is sealed.
