🔍 Key Concepts

• Boiler combustion control system purpose (maintain proper burning of fuel for efficiency and safety) • Difference between controlling total air flow vs. controlling the proportion of air to fuel • What device is designed to keep the fuel-to-air proportion correct over a wide load range

💭 Think About

• Ask yourself: Which option directly keeps the relationship between how much fuel is burned and how much air is supplied in the correct proportion, regardless of load? • Consider which device is usually the master control that automatically trims both fuel and air to maintain efficient combustion, instead of just changing one side of the system. • Think about which setting you would adjust to get maximum combustion efficiency across the operating range, not just to increase or decrease flow of one medium.

✅ Before You Answer

• Identify which option specifically refers to a ratio or proportion between two variables rather than a single flow or pressure. • Verify which components (back pressure, dampers, air regulators) mainly affect quantity only (fuel or air) and which one actually maintains the fuel-air balance. • Ask: For best boiler efficiency, do engineers usually focus on a precise fuel/air ratio or only on air volume or oil pressure alone?
