What is the ultimate reading of CO2 (carbon dioxide) for natural gas?

The ultimate reading of CO2 for natural gas is typically around 11.9%. This value reflects the optimal CO2 concentration in the combustion products of natural gas, ensuring efficient combustion and minimal environmental impact.

Natural gas combustion ideally produces carbon dioxide in a balanced way where the fuel is completely combusted, maximizing energy output and minimizing harmful emissions. If the CO2 concentration deviates significantly from this value, it may indicate incomplete combustion or other efficiency issues. Understanding the proper reading of CO2 helps technicians ensure that gas appliances are functioning correctly and safely.

Values like 9.9%, 10.9%, and 13.9% do not represent the optimize ratio for natural gas combustion and therefore are less relevant in this context. Maintaining a reading closer to 11.9% is crucial for efficiency and ensuring that combustion gases are within acceptable limits for safety and environmental standards.
