What is the effect of high CO2 levels in boiler emissions?

High levels of CO2 in boiler emissions are typically indicative of a potentially hazardous situation. While some CO2 is a normal byproduct of combustion, excessively high concentrations can suggest incomplete combustion or other combustion inefficiencies. This can lead to unsafe conditions, including buildup of carbon monoxide (a toxic gas), reduced efficiency, and increased risk of overheating or failure of boiler components. Monitoring CO2 levels is therefore crucial for maintaining safe operating conditions and optimizing fuel usage. Increased attention to CO2 levels is important for both safety and regulatory compliance.
