Combustion Air Calculator

Share this calculator:

The purpose of this Combustion Air Calculator is to assist you in calculating the quantity of combustion air needed for a certain combustion process. This calculator makes it easy to determine how much air will be required for combustion processes in a variety of settings, including industrial applications, heating, ventilation, and air conditioning (HVAC), and more.




How To Use The Combustion Air Calculator

Using the calculator is straightforward. Enter the temperature of the combustion process in degrees Celsius and the percentage of oxygen required for optimal combustion. Once you click the “Calculate” button, the calculator instantly computes the amount of combustion air needed.

Here’s a breakdown of the calculation performed by the Combustion Air Calculator:

  1. Input: Temperature (in °C)
    • The user enters the temperature of the combustion process in degrees Celsius through the input field.
  2. Input: Oxygen Percentage (in %)
    • The user enters the desired oxygen percentage for optimal combustion through the input field.
  3. Calculation: Combustion Air
    • The calculator takes the input values of temperature and oxygen percentage to compute the required combustion air.
    • It uses the ideal gas law and the ratio of oxygen to air in atmospheric conditions (which is approximately 21%) to determine the amount of air needed for the specified oxygen percentage.
    • The calculation formula is: Combustion Air = (Oxygen Percentage / 21) * (273 / (273 + Temperature))
      • The oxygen percentage is divided by 21 to obtain the proportionate air requirement.
      • The temperature value is converted to Kelvin by adding 273 to it, as the ideal gas law requires temperatures in Kelvin.
      • The proportionate air requirement is multiplied by the temperature conversion factor to calculate the combustion air value.
  4. Display: Result
    • The calculated combustion air value is displayed prominently in the output area of the calculator.
    • The result is presented in bold and red text to make it easily visible.

By following this breakdown, the Combustion Air Calculator enables users to input the temperature and oxygen percentage, and then it calculates and presents the precise amount of combustion air required for optimal combustion based on the provided parameters.
