Question 1 of 27070

When heated, brickwork in a boiler is kept from buckling by the installation of __________.

🔍 Key Concepts

• Thermal expansion of furnace/boiler brickwork when heated • How rigid vs. movable supports affect brick structures under heat • Which components in boilers are specifically designed to allow movement rather than provide insulation

💭 Think About

• Ask yourself: when brickwork heats up and expands, what feature would allow it to change size without cracking or buckling? • Which of the choices is primarily meant to control movement of the structure, not just temperature or support? • Think about the difference between protecting against heat loss and allowing parts to shift as they get hot.

✅ Before You Answer

• Identify which options are mainly for insulation (reducing heat transfer) versus for movement/expansion control. • Consider which device is commonly used in many structures (piping, boilers, bridges) to accommodate thermal expansion. • Verify that your choice would actually prevent buckling by letting the brickwork move or expand, rather than just making it hotter or cooler.
