🔍 Key Concepts

• Role of auxiliary exhaust steam in a steam plant (heating, deaeration, small auxiliaries) • Where exhaust steam from auxiliary machinery is normally collected before being used for heating or other services • Function and steam flow through main condenser, feed pumps, distilling plant, and air heaters

💭 Think About

• Think about which component actually receives and collects exhaust steam from many auxiliary machines, rather than just using steam itself • Ask yourself: which of these choices is normally on the low‑pressure side of the steam cycle where exhaust steam would logically be routed? • Consider the typical path: boiler → turbine/auxiliaries → exhaust → ? → condensate return. Where on that path would you tap steam for auxiliary exhaust uses?

✅ Before You Answer

• Verify which component is designed as a collection point for exhaust steam from turbines and auxiliaries • Check which item is part of the condensing system rather than simply a steam consumer • Confirm which unit would most logically supply low‑pressure steam for heating or other ship services
