How to Use the Calculator
- Select the type of fuel from the dropdown menu. For standard fuels like natural gas, propane, etc., the calculator provides default air-fuel ratios.
- Enter the fuel flow rate in kilograms per hour (kg/h).
- If you're using a non-standard fuel, select "Other" and enter the fuel composition. The calculator will prompt you to input the air-fuel ratio.
- Click the "Calculate" button to determine the theoretical air requirement and air-fuel ratio.
- The results will be displayed in the respective fields.
Working Principle
The calculator determines the theoretical air required for complete combustion based on the stoichiometric air-fuel ratio. For complete combustion, each unit of fuel requires a specific amount of air.
Common Air-Fuel Ratios
- Natural Gas: 9.5 kg air per kg of fuel
- Propane: 9.5 kg air per kg of fuel
- Butane: 9.5 kg air per kg of fuel
- Methane: 9.5 kg air per kg of fuel
- Ethane: 9.5 kg air per kg of fuel
Note: These are approximate values. For precise calculations, consider factors like fuel impurities, combustion efficiency, and environmental conditions.
