What is the purpose of rolling/accelerating a new steam turbine before putting it into service?
Rolling or accelerating a new steam turbine before commissioning is a critical step followed by experienced Power turbine manufacturers to ensure safe and reliable operation. Slow rolling helps confirm smooth rotation of the rotor, shaft, and bearings, allowing early detection of rubbing, noise, or alignment issues. Gradual acceleration ensures uniform heating of turbine components, preventing thermal stress or distortion. This process also helps remove moisture from steam paths, protecting blades from erosion. Vibration levels are monitored at low and medium speeds to identify imbalance. In addition, control systems, governors, and safety trips are tested to confirm proper response. Overall, rolling and acceleration reduce failure risks and ensure long-term turbine performance.
