🔍 Key Concepts
• Flash type evaporator operating temperature and why around 160°F (70°C) is important
• How distillate quality/salinity is controlled and what happens when conditions are not ideal
• Purpose of an automatic three-way solenoid dump valve in an evaporator system
💭 Think About
• Ask yourself: if the feed water is too cool, will evaporation and separation be more efficient, less efficient, or about the same?
• Consider what the system should do with distillate when the operating temperature drops: should it store it, discard it, or would another component be affected first?
• Think about which component (storage tanks, demisters, bilge dump, first-effect) is directly related to protecting the quality of the produced fresh water.
✅ Before You Answer
• Verify how low feed temperature affects evaporation rate and salt carry‑over in a flash evaporator
• Check the function of the three-way solenoid valve: is it designed to protect the tanks, the bilge, the demisters, or the first-effect?
• Confirm which condition (low temperature, scaling, priming) would most likely trigger dumping distillate instead of sending it to storage.
