Low pressure steam is used to keep air from leaking into turbine casing along the turbine shaft. For this purpose, which of the following steam systems is used?

🔍 Key Concepts

• Purpose of gland systems on steam turbines (what problem they solve) • Difference between sealing steam and leak-off steam around the shaft glands • Typical pressure and temperature of steam used to prevent air ingress into a condenser-type turbine

💭 Think About

• Ask yourself: Is the question about removing steam that has already leaked past the glands, or about supplying steam to form a barrier so air cannot get in? • Which system’s main job is to protect the vacuum in a condensing turbine by keeping air out at low-pressure locations? • Would superheated, high‑temperature steam be appropriate right at the shaft seals, or is a lower‑pressure, lower‑temperature steam usually used?

✅ Before You Answer

• Identify which choice describes a system that supplies low‑pressure steam to the shaft glands, not removes it. • Eliminate any option that clearly relates to high‑pressure or superheated steam, since the question specifies low pressure steam. • Make sure the chosen system’s primary function is to prevent air ingress at the turbine shaft rather than just handling or recovering leakage.
