Question 1 of 27070

To provide emergency feedwater supply to a steaming boiler, if it becomes necessary to secure the DC heater, suction should be taken on the distilled water tank using the __________.

🔍 Key Concepts

• Emergency feedwater arrangements on steam plants • Normal role of the DC (de-aerating) heater in the feed system • Which device can take suction from a distilled water tank and safely deliver water to a steaming boiler

💭 Think About

• Trace the normal path of feedwater from the condenser to the boiler and identify where the DC heater fits in that line • Ask which listed piece of equipment is specifically intended for emergency use when normal feed paths are unavailable • Consider which option can operate with suitable pressure and water quality to feed a boiler directly and safely

✅ Before You Answer

• Verify which device is specifically designated as emergency feed equipment in typical steam plant diagrams or descriptions • Check whether each option normally takes suction from the distilled water tank or from another point (such as the condenser hotwell or main feed system) • Confirm which option can provide adequate pressure to overcome boiler pressure and feed a steaming boiler under emergency conditions
