What two measurements are used to determine combustion efficiency?

• A. Flue gas pressure and water temperature
• B. Flue gas temperature and percentage of CO2
• C. Oxygen levels and fuel type
• D. Heat output and exhaust temperature

Answer: (B)

Combustion efficiency is a measure of how effectively a fuel is burned to produce heat. The correct answer involves the flue gas temperature and the percentage of carbon dioxide (CO2) emitted during the combustion process. Flue gas temperature is significant because it indicates how much heat is going up the chimney instead of being used for heating. Ideally, you want to minimize waste heat in the flue gases, so monitoring this temperature can help assess how well the combustion process is converting fuel into usable heat. The percentage of CO2 in the flue gases is a clear indicator of the combustion process's efficiency. A higher level of CO2 suggests more complete combustion of the fuel, meaning that more of it is being converted into energy rather than being wasted or producing harmful emissions. An optimal level of CO2 is typically targeted to ensure that combustion is occurring efficiently. Together, these two measurements enable you to evaluate how well the combustion system performs, allowing for adjustments that can enhance efficiency and reduce emissions.
