Question 1 of 27070

In a two stage flash evaporator, heated feed water is vaporized in the __________.

🔍 Key Concepts

• Flash evaporation process – where liquid suddenly vaporizes when pressure drops • Difference between heating surfaces (where temperature is raised) and flash chambers (where actual boiling/flash occurs) • Role of vapor separators/effects in separating steam from brine droplets

💭 Think About

• Ask yourself: In a flash evaporator, does the water boil because of added heat at that point, or because the pressure is reduced after it has already been heated? • Which component is mainly for raising the feed water temperature, and which component is mainly for allowing flashing (rapid vaporization) to occur? • What is the job of a vapor separator compared with the place where flashing actually happens?

✅ Before You Answer

• Identify which option names a heating device rather than a flashing space • Identify which option(s) describe low‑pressure chambers designed for rapid vaporization of hot feed water • Confirm which component’s primary purpose is separation of droplets, not initial vaporization
