🔍 Key Concepts

• Complete vs. incomplete combustion of fuel in a boiler (relationship between CO2, CO, and O2) • How carbon monoxide (CO) forms when there is not enough oxygen or poor mixing • How CO2 levels change when combustion is more or less efficient

💭 Think About

• If combustion were perfectly complete, what main carbon-containing gas would you expect in the stack, and what gas would be almost zero? • When combustion becomes less complete, which gas increases first: CO2 or CO, and what happens to the other? • Think about which pattern (high/low CO2 and CO) best reflects a lot of unburned or partially burned fuel.

✅ Before You Answer

• Compare each choice to the ideal complete combustion case: high CO2, almost no CO • Look for the choice that shows evidence of significant incomplete burning (more CO) AND not achieving high CO2 • Verify which combination indicates that the boiler is burning fuel poorly, wasting fuel and producing more CO.
