Q

In an automatically fired boiler, the steam pressure regulator controls the supply of fuel oil to the burners by responding to variations in the __________.

🔍 Key Concepts

• Automatic boiler combustion control and what variable it is primarily trying to keep constant • Relationship between steam demand, steam pressure, and how much fuel is needed • Difference between controls that maintain water level versus those that control steam pressure

💭 Think About

• When the ship’s steam consumption suddenly increases, which measured variable changes first and most directly, telling the system to add more fuel? • Which option represents a system pressure that reflects overall load on the boiler rather than a condition local to just one component? • Which of the listed items is normally controlled by a separate device (like a feedwater regulator) instead of the fuel control?

✅ Before You Answer

• Identify which choice is a true system load indicator for the boiler, not just a local or secondary condition • Separate in your mind the function of a feedwater level controller versus a fuel/combustion controller • Ask: which parameter would the boiler designer most logically choose as the feedback signal to keep steam production matched to demand?
