🔍 Key Concepts

• Boiler refractory firebrick support methods on marine boilers • Difference between mechanical anchors and mortar only attachment • How brick shapes/slots interact with metal anchors in high-temperature areas

💭 Think About

• Think about what happens to both steel casing and firebrick when the boiler cycles from cold to very hot. Which method allows for expansion and contraction without the brick falling out? • Ask yourself whether ships’ boiler bricks are usually held mainly by glue-like mortar or by some kind of interlocking mechanical arrangement. • Visualize the inside of a boiler casing: how would maintenance crews replace a damaged brick section without having to cut or burn off a lot of hardware?

✅ Before You Answer

• Verify which option provides a positive mechanical connection between brick and steel casing, not just surface adhesion. • Check which choice would best resist vibration and thermal shock common in marine service. • Eliminate any option that would likely crack or loosen quickly as temperatures change and the casing flexes.
