🔍 Key Concepts

• Typical concentrations of CO₂, O₂, and CO in normal oil-fired or diesel boiler flue gas • How test equipment ranges and sensitivities affect the sequence of gas measurements • Why measuring a gas with a high concentration first can impact later readings

💭 Think About

• Which of these gases is normally present in the highest percentage in properly adjusted combustion flue gas? • Which gas needs the most sensitive/low-range instrument setting, and would be easier to measure after you already know the approximate excess air from another gas? • If measuring one gas uses up or dilutes the sample, which gas should be checked last so that its reading is least affected?

✅ Before You Answer

• Know the normal flue gas composition for efficient combustion (approximate order of magnitude of CO₂, O₂, and CO) • Consider which instrument often has coarser scale and can tolerate sample disturbance versus which requires a more precise, stable sample • Verify which gas is usually used to judge excess air and combustion efficiency, and how that suggests whether it should be read earlier or later in the sequence
