Scale formation in a flash-type evaporator is usually found in the _______________.
AI Explanation
The correct answer is C) tubes of the salt water feed heater.
In a flash-type evaporator, scale formation is typically found in the tubes of the salt water feed heater. This is because the salt water feed heater is where the seawater is preheated before entering the flash chamber, and as the water temperature increases, dissolved salts and minerals can precipitate out and form scale deposits on the heat exchanger surfaces.
The other options are incorrect because the flash chamber walls, distiller condenser tubes, and air ejector condenser tubes are not the primary locations where scale formation is usually observed in a flash-type evaporator system.
