Warping of superheater screen tubes can be caused by __________.

🔍 Key Concepts

• thermal shock and how rapid temperature changes affect metal tubes • difference between steady high temperature vs. sudden cooling after overheating • how gas flow and baffling influence tube temperature distribution

💭 Think About

• Think about what physically makes a straight metal tube bend or warp. Is it more about the absolute temperature, or uneven/rapid temperature changes in different parts of the tube? • Compare conditions that cause gradual metal creep versus sudden distortion. Which of the choices best matches a sudden, uneven stress on the tube metal? • Ask yourself which condition would cause one side or section of a tube to contract much faster than another side or section.

✅ Before You Answer

• Identify which options describe rate of temperature change rather than just "high" temperature. • Consider which options would likely produce uneven temperature along or around the tube (inside vs. outside, top vs. bottom). • Before choosing, be sure the option you pick clearly involves thermal shock or uneven cooling/heating, not just a hot environment.
