An intermediate chamber is used in conjunction with labyrinth packing on main turbine shaft glands to provide a __________.

🔍 Key Concepts

• Labyrinth packing purpose on main turbine shaft glands • Function of an intermediate chamber between stages of packing • Relationship between shaft gland arrangements and condenser vacuum / sealing steam systems

💭 Think About

• Think about what problem the intermediate chamber is solving in a turbine gland system: is it protecting vacuum, protecting pressure, or moving steam somewhere else? • Which of the options describes something that would logically be connected to the space between packing rings, rather than to the throttle or directly to the condenser? • In low internal pressure or low vacuum conditions, what risk exists at the shaft glands, and how would the intermediate chamber help manage that?

✅ Before You Answer

• Identify the primary job of shaft glands with labyrinth packing on a main turbine (what are they trying to prevent or control?). • Decide whether the intermediate chamber is more likely connected to sealing steam / leak‑off lines or to the air ejector suction / condenser. • Eliminate any answers that clearly relate to parts of the system farther away from the shaft gland (for example, throttle valves or air ejector inlets).
