Which of the following problems can occur from improper main turbine warm-up?

Question 1 of 27070

Which of the following problems can occur from improper main turbine warm-up?

🔍 Key Concepts

• Thermal expansion and how metal components change size when heated too quickly • How rotors, blades, and casings fit together with very tight clearances in a turbine • Why manufacturers specify a controlled warm‑up rate for large turbines

💭 Think About

• If the turbine is heated unevenly or too fast, what could happen to parts that must stay precisely aligned, like the rotor and blades? • Think about the turbine casing: if one side gets hotter faster than the other, what kind of mechanical problem might that create? • Which of the listed problems are directly related to changes in shape, size, or alignment due to quick temperature changes?

✅ Before You Answer

• For each option, ask: "Could this realistically be caused by rapid or uneven heating of turbine parts?" • Consider whether only one component (rotor, blades, or casing) would be affected, or if all might be vulnerable to poor warm‑up practices. • Verify your thinking against the idea that tight clearances in turbines make them sensitive to even small distortions or misalignments.
