A fossil fuel furnace operating with CO2 levels 1% lower than the design parameters can lose how much of its energy efficiency?

In the operation of fossil fuel furnaces, carbon dioxide (CO2) levels are critical indicators of combustion efficiency. When CO2 levels are lower than the design parameters, it typically suggests that the combustion process is not complete, resulting in an increase in unburned fuel and associated losses.

When the CO2 levels decrease by 1%, this often indicates that some fuel is not being converted into energy, leading to a reduction in the overall energy efficiency of the furnace. Research and industry standards suggest that a decrease in CO2 levels by approximately 1% can correlate to a loss in energy efficiency of around 5%.

This relationship is vital for understanding how adjustments in CO2 levels can impact the performance of combustion systems. Maintaining optimal combustion conditions, including proper CO2 levels, is crucial for maximizing energy efficiency and minimizing waste in fossil fuel applications.
