🔍 Key Concepts

• Marine steam power plant feedwater system arrangement (first stage, second stage, and deaerating/feed tanks) • Where auxiliary exhaust steam is routed during full‑power operation • Difference between bleed steam from turbines and auxiliary exhaust

💭 Think About

• Think about what happens to steam from the main and auxiliary turbines after they have done their work—where does that exhaust go during normal sea speed? • Which steam source is most suitable (pressure and temperature) for heating and deaerating large quantities of feedwater continuously? • During full load at sea, which system is designed to recover waste heat rather than ‘use up’ high‑value steam?

✅ Before You Answer

• Verify which heaters typically use bled (extraction) steam versus which use exhaust steam in a standard marine steam plant diagram • Check the usual steam source connected to the deaerating feed tank (DFT) in your training manual’s system schematic • Confirm that the chosen source operates and is available continuously at sea under full power, not only in port or at low loads
