Q

The final heating of the feed water in a flash type distilling plant is carried out by __________.

🔍 Key Concepts

• Flash-type distilling plant flow path – trace the sequence: feedwater heater → first-stage feedbox → flash chamber → condenser • Difference between sensible heating (raising temperature without boiling) and vaporization/flash • Purpose of distiller condensers in multi-stage plants

💭 Think About

• In a flash-type unit, at what point is the feed water brought up to its final temperature just before flashing into vapor? • Which component’s main job is to remove heat from vapor, and which component’s main job is to add heat to incoming feed water? • How does the condensate temperature in later stages help preheat feed water as it moves forward in the system?

✅ Before You Answer

• Trace the temperature changes of the feed water through each listed component and decide where it reaches its highest temperature before flashing • Confirm which component is primarily a heater for feed water versus a condenser for vapor • Verify how heat recovery from condensing vapor is used in multi‑stage distillers to improve efficiency
