🔍 Key Concepts

• Automatic boiler combustion control – what variable must be controlled first to adjust fuel safely? • Relationship between steam pressure, air flow, and fuel flow in an automatically fired boiler • Which components actually measure conditions vs. which simply respond to them

💭 Think About

• Ask yourself: in an automatically fired boiler, what is the primary condition that tells the system to increase or decrease the fuel oil flow? • Think about which option directly controls FUEL, and which options are more related to AIR or WATER control instead. • Which device would most likely send a control signal to a fuel metering valve, rather than just mechanically changing air or sensing water level?

✅ Before You Answer

• Identify which choice is associated with steam pressure sensing and how that relates to fuel demand. • Separate in your mind the functions of air control, water level/feedwater control, and fuel control – only one should be directly tied to the fuel oil metering valve in this question. • Verify which device would create a control signal (not simply a passive mechanical effect) that can be used to position the fuel metering valve.
