Main propulsion steam turbine casing drains generally discharge to the ________.

Question 1 of 27070

Main propulsion steam turbine casing drains generally discharge to the ________.

🔍 Key Concepts

• Function and normal operating pressure of main propulsion steam turbine casing drains • Where condensate and non-contaminated drains are usually routed in a closed feedwater/condensate system • Difference in purpose between contaminated drain tank, atmospheric drain tank, and bilge

💭 Think About

• Ask yourself: Are turbine casing drains normally considered clean (condensate) or dirty/contaminated? • Which destination would allow recovery of heat and water back into the steam cycle instead of wasting it? • In normal operation, would you want these drains exposed to the atmosphere or kept under vacuum/controlled conditions?

✅ Before You Answer

• Verify which tank/system is directly associated with the condenser and condensate return line-up on a typical steam plant diagram. • Check which option would most likely be used for oily or chemically contaminated drains, not for relatively clean condensate. • Confirm whether turbine casing drains normally operate under vacuum or atmospheric conditions in a main propulsion plant.
