🔍 Key Concepts

• Purpose of the turning gear on a main turbine before warm‑up • What happens to a turbine when it sits and cools unevenly (rotor bowing / hogging) • Which component actually rotates vs. which ones are stationary (bearings, glands, nozzles, rotor)

💭 Think About

• When a turbine has been stopped for a while, what physical changes can occur inside due to uneven temperature or cooling? Which part of the turbine would be most affected by that? • What does the turning gear actually move when it is engaged? Think about which choice corresponds to the part being slowly rotated. • If you fail to slowly roll the turbine before putting steam on, which part is most at risk of rubbing, bending, or going out of alignment?

✅ Before You Answer

• Identify which of the four choices is the rotating element of the turbine. • Ask yourself: which component is most likely to warp or bow if left in one position and then heated quickly? • Eliminate any options that are primarily stationary components or systems that wouldn’t be directly stressed by not rolling the turbine.
