Q

Which type of packing is primarily utilized to control steam leakage from the casing of a modern auxiliary turbine?

🔍 Key Concepts

• Function of packing around turbine casings and shafts • How steam is sealed in high‑pressure rotating machinery • Typical construction and purpose of labyrinth seals

💭 Think About

• Think about whether this packing actually touches the shaft tightly, or relies on a different principle to restrict steam flow. • Ask yourself which choice is commonly associated with high-speed turbines rather than slow, reciprocating equipment. • Consider which material or design would best withstand high temperature and high velocity steam without rapid wear.

✅ Before You Answer

• Verify how turbine shaft seals usually work in marine engineering texts or training materials. • Check which of the options is a design/type of seal rather than just a material name. • Confirm which packing method depends on creating a series of restrictions or chambers to reduce steam leakage.
