🔍 Key Concepts

• thermal shock in refractory (furnace brick) materials • how rapid temperature changes affect brickwork vs gradual changes • which boiler operations introduce sudden cooling or heating to hot surfaces

💭 Think About

• Which choice involves the fastest sudden temperature change to the furnace brick: heating or cooling? • Think about which action would expose very hot brickwork to a much cooler fluid or air stream in a short time. • For each option, imagine the temperature of the brickwork and what happens to it in the next few minutes – does it change slowly or abruptly?

✅ Before You Answer

• Identify which option creates a rapid temperature difference between the brick surface and what it is exposed to. • Eliminate options that describe gradual or controlled temperature changes. • Focus on the choice where a cold medium contacts or flows past very hot metal/brick surfaces quickly.
