Flue Gas Volume Calculator
Total Exhaust Volume From a Combustion Event
Every kilogram of fuel burned produces a predictable volume of flue gas, depending on fuel composition and excess air level. Multiplying that per-kg factor by total fuel burned gives the total flue gas volume produced.
The Formula
Total Flue Gas Volume = Fuel Mass × Flue Gas Volume per kg Fuel
Worked Example
Burning 200 kg of fuel that produces 12.5 Nm3 of flue gas per kg:
Volume = 200 × 12.5 = 2,500 Nm3
How to Use This Calculator
- Enter the total Fuel Mass burned.
- Enter the Flue Gas Volume produced per kg of fuel.
- Select Calculate to get total flue gas volume.
