🔍 Key Concepts

• Refractory materials and their purpose in high-temperature areas • Difference between structural refractories (load‑bearing / gas-side) and insulating refractories (primarily for thermal insulation) • Typical uses of firebrick, plastic chrome ore, and castable insulation in boiler/furnace construction

💭 Think About

• Think about which materials are designed to be directly exposed to hot combustion gases versus those meant mainly to reduce heat loss. • Consider which material might not have enough strength, abrasion resistance, or temperature rating to serve as a gas-side layer or a floor material. • Ask yourself: in a wall already provided with 2-inch thick insulation block, which material would you choose for the hot-face lining that actually sees the flame and gas flow?

✅ Before You Answer

• Verify which of the listed materials is primarily an insulating material rather than a heavy-duty hot-face refractory. • Check typical maximum service temperature and erosion/abrasion resistance for each material type. • Confirm which materials are normally used as working linings (firebox walls/floors, gas-side surfaces) versus backup insulation only.
