🔍 Key Concepts

• Steam turbine-generator protection systems and why they trip to prevent damage • Role of the condenser and vacuum / back pressure in a marine steam plant • What happens to turbine operation when condenser vacuum is lost or reduced

💭 Think About

• Ask yourself: What does the term back pressure refer to in relation to a turbine exhaust and condenser? • Which of these conditions would most likely cause a loss of condenser vacuum and an unsafe rise in exhaust (back) pressure? • Which of the listed conditions would threaten turbine efficiency and mechanical safety by changing the pressure at the turbine exhaust side?

✅ Before You Answer

• Be clear on the difference between lube oil pressure trips and back pressure trips — they protect against different hazards. • Connect insufficient vs. excessive cooling water to what happens to condenser temperature and vacuum (and therefore back pressure). • Verify which listed condition directly affects condenser vacuum/back pressure, not some other part of the system.
