🔍 Key Concepts

• Complete vs. incomplete combustion in oil- or gas-fired boilers • How carbon dioxide (CO₂) and oxygen (O₂) levels change with excess air • Why carbon monoxide (CO) appears in flue gas and what it indicates

💭 Think About

• Which gas tells you that combustion is complete and efficient, and how does its percentage change as excess air increases? • Which gas directly indicates unburned fuel or incomplete combustion in the furnace? • Is nitrogen actively involved in the combustion reaction, or is it mostly an inert background gas in the flue sample?

✅ Before You Answer

• Identify which gases are direct products of combustion of carbon in the fuel • Identify which gas is a clear indicator of incomplete combustion (wasted fuel / unsafe condition) • Decide whether nitrogen content meaningfully reflects combustion efficiency, or simply tracks the amount of air passing through the boiler
