Enter the concentration of CO2 (ppmv) and the concentration of CO (ppmv) into the calculator to determine the Combustion Efficiency. 

Combustion Efficiency Formula

The following formula is used to calculate the Combustion Efficiency. 

Ecombustion = CO2 / (CO2 + CO) *100
  • Where Ecombustion is the Combustion Efficiency (%)
  • CO2 is the concentration of CO2 (ppmv) 
  • CO is the concentration of CO (ppmv) 

To calculate the combustion efficiency, divide the concentration of CO2 by the sum of the concentrations of CO2 and CO, then multiply by 100.

How to Calculate Combustion Efficiency?

The following two example problems outline how to calculate the Combustion Efficiency.

Example Problem #1:

  1. First, determine the concentration of CO2 (ppmv). In this example, the concentration of CO2 (ppmv) is given as 10.
  2. Next, determine the concentration of CO (ppmv). For this problem, the concentration of CO (ppmv) is given as 2.
  3. Finally, calculate the Combustion Efficiency using the equation above: 

Ecombustion = CO2 / (CO2 + CO) *100

Inserting the values from above and solving the equation: 

Ecombustion = 10 / (10 + 2) *100 = 83.33 (%)

FAQ

What factors can affect combustion efficiency?

Combustion efficiency can be influenced by several factors including the fuel type and quality, the condition and design of the combustion system, the air-to-fuel ratio, and the operating conditions such as temperature and pressure. Variations in any of these factors can lead to changes in the efficiency of the combustion process.

Why is it important to measure combustion efficiency?

Measuring combustion efficiency is crucial for optimizing fuel usage and minimizing environmental impact. High combustion efficiency means that fuel is being used effectively, which can lead to cost savings and reduced emissions of pollutants and greenhouse gases. It also helps in identifying system malfunctions or areas for improvement in combustion processes.

How can combustion efficiency be improved?

Improving combustion efficiency can involve several strategies, such as optimizing the air-to-fuel ratio, using higher quality fuels, maintaining the combustion equipment regularly, and implementing advanced control systems. Additionally, retrofitting older systems with newer, more efficient technologies can also significantly enhance combustion efficiency.
