🔍 Key Concepts

• Boiler combustion control – the relationship between air supply (forced draft) and fuel supply • Safe firing rate changes – avoiding smoky fires, flameout, or furnace explosions when increasing load • Difference between air quantity (pressure/volume) and air distribution (burner registers)

💭 Think About

• When you increase the firing rate (more heat), what must happen to the air supply so combustion stays complete and safe? Think about which one must change first to avoid a rich (fuel-heavy) mixture. • What could happen if you add fuel faster than you add air in an enclosed furnace? Which choice would prevent that condition? • Look at the options that directly change overall forced draft pressure versus those that mainly redirect or split existing air. Which is more directly tied to safe firing rate increase?

✅ Before You Answer

• Identify which options actually change total air supply/pressure to the furnace, not just how it is distributed. • Consider which sequence maintains a slightly lean or balanced air-fuel ratio during a load increase, rather than a fuel-rich mix. • Verify which actions (register adjustment vs. system pressure change) are typically used as fine-tuning versus primary combustion control.
