🔍 Key Concepts

• Function of a deaerating feed tank in a steam plant and how it is supplied (steam, drains, returns) • How pressure can build up in a closed vessel when connected to higher-pressure systems • Purpose and operation of a relief valve on pressure vessels

💭 Think About

• Which of the listed connections can introduce steam or condensate at a pressure higher than the normal operating pressure of the deaerating feed tank? • If that supply control valve were to fail open, which connection could rapidly increase internal pressure inside the tank? • Which options describe flows that are mostly at or near condenser pressure or atmospheric pressure, and which describe flows that could be significantly above atmospheric pressure?

✅ Before You Answer

• Identify which line(s) normally carry high-pressure steam or drains versus low-pressure or near-vacuum flows • Consider which connection, if uncontrolled, poses the greatest overpressure hazard to the tank shell • Verify that the chosen option directly relates to a credible overpressure source, not just large volume or normal drainage

Because the tank receives high-pressure drains.

Because the tank receives auxiliary exhaust.

Because the tank drains to the main condenser.
