🔍 Key Concepts

• Study the flow path around the brine space of the distiller (chamber 23) and trace where concentrated brine could continuously leave the unit. • Compare the purpose of a flow‑control orifice (like item 19) versus a drain valve versus a jet ejector in typical distiller systems. • Look at how the hydrokineter (21) is piped and decide whether it is meant to circulate/heat water or to discharge brine overboard.

💭 Think About

• If excess brine is removed "during normal operation," would this be done by a manual valve or by an automatically acting device in the circuit? • Follow the piping from items 19, 21, and 22: which one actually leads to an outlet that can carry brine away from the distiller shell while it is running? • Ask yourself which component is designed to control incoming feed, and which is designed to continuously draw off a side stream of liquid. That second function is what prevents brine buildup.

✅ Before You Answer

• Verify which symbol in the illustration represents a jet ejector and see where its suction line connects (brine space or somewhere else). • Confirm whether orifice 19 is in the feed inlet line or the brine discharge line. • Check if the drain valve shown is labeled or drawn as a normally closed/manual valve, which would NOT operate continuously during normal steaming.
