🔍 Key Concepts

• refractory material purpose in a boiler furnace (protects metal from heat and rapid temperature change) • effects of thermal shock vs. steady temperature on brick/ceramic materials • difference between problems caused by fuel quality / water treatment and those affecting steel vs. refractory

💭 Think About

• Ask yourself: Which option changes the temperature of the refractory surface the fastest and most violently? • Which choices mainly damage metal pressure parts (tubes, drum, shell) rather than the brick/ceramic lining? • Think about a brick or ceramic tile: what kind of temperature exposure is most likely to crack or spall it?

✅ Before You Answer

• Identify which answer choice directly produces thermal shock in the refractory rather than long-term slow heating. • Separate issues that cause corrosion/scale in tubes from those that cause cracking or spalling of the furnace lining. • Verify which conditions would make the refractory expand and contract repeatedly in a short time, stressing the material.
