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)

## 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 (%)

Example Problem #2:

Using the same process as above, first define the variables required by the formula. In this case, these values are:

concentration of CO2 (ppmv) = 8

concentration of CO (ppmv) = 3

Entering these values yields:

Ecombustion = 8 / (8 + 3) *100 = 72.72 (%)
