Q

Throttling a burner air register on an auxiliary boiler could result in __________.

🔍 Key Concepts

• air-fuel ratio in boiler combustion • effects of insufficient air supply on flame quality • relationship between excess air and soot/smoke formation

💭 Think About

• What happens to combustion when you reduce the amount of combustion air but keep the same fuel flow? • How does a lack of air affect the color and cleanliness of the flame and stack gases? • Would throttling air usually lead to cleaner or dirtier heat-transfer surfaces inside the boiler?

✅ Before You Answer

• Check how restricted air flow changes the completeness of combustion. • Consider whether throttling air would normally increase or decrease soot deposits. • Think about whether better combustion generally requires more or less available oxygen for a given fuel rate.
