Question 1 of 27070

The temperature of the steam supply to the saltwater feed heater, in a flash type evaporator can be manipulated by a/an __________.

🔍 Key Concepts

• Flash type evaporator operation – how steam heats seawater to produce distillate • Methods of controlling steam temperature vs. controlling steam pressure or flow • Difference between a bypass valve, an attemperator, and a sensor/valve control loop

💭 Think About

• Ask yourself: which device is specifically designed to change the temperature of the steam itself, not just the pressure or on/off flow? • Which options are actual control devices acting directly on the steam, and which are only sensing or indirect controls? • In typical marine evaporator systems, how is overheating of heating surfaces or excessive vapor temperature prevented?

✅ Before You Answer

• Identify which choice is primarily a pressure control device, not a temperature control device. • Identify which choice involves only a sensor and not a means of directly changing steam temperature. • For each remaining device, ask: does it act by mixing or diverting steam/condensate in a way that directly affects the steam temperature entering the heater?
