🔍 Key Concepts

• Thermal shock and how it affects refractory materials in boilers • Difference between slow, uniform temperature changes and sudden temperature changes on brickwork and castable refractory • What happens to previously baked and cured refractory when exposed to quick temperature swings after it has been in service

💭 Think About

• Think about which condition creates the largest temperature gradient between the hot face and the cold face of the refractory in the shortest time • Consider whether brand‑new refractory and previously fired refractory respond the same way to temperature changes, or if one is more brittle and crack‑prone • Ask yourself when cracks and spalling (pieces popping off) are most likely to occur: when heating up, when running steady, or when shutting down

✅ Before You Answer

• Be clear on what baked out and fired means in terms of moisture content and curing of the refractory • Identify which option involves the most severe thermal stress over a short time period • Rule out any choices that mainly describe steady, uniform temperature conditions rather than sudden changes
