Question 1 of 27070

While underway at sea, the feed water inlet temperature to a boiler economizer is determined by the __________.

🔍 Key Concepts

• Function of a boiler economizer in a steam plant and what fluid it heats • Where feedwater temperature is normally controlled and adjusted in a marine steam system • Difference between superheating, desuperheating, and turbine bleed steam uses

💭 Think About

• Which component in the choices directly affects the temperature of water going into the economizer, rather than the steam leaving the boiler? • In a typical marine steam plant, where is cooler feedwater mixed with or heated by steam to reach a desired inlet temperature? • Which option represents a point where steam is intentionally cooled to control feedwater temperature?

✅ Before You Answer

• Identify which choice is directly connected to feedwater control, not just steam conditions elsewhere in the system • Eliminate any option that mainly affects steam temperature after the boiler rather than water entering the economizer • Focus on the component used to adjust temperature by mixing steam and water before it reaches the economizer
