Fuel Gases - Combustion Values
Combustion values for fuel gases like natural gas, propane and butane - Btu per cubic feet.
Combustion (heat) values for some fuel gases:
| Fuel Gas | Combustion Value (Btu/ft3) | Specific Gravity |
|---|---|---|
| Acetylene | 1498 | 0.91 |
| Blast furnace gas | 92 | 1.02 |
| Butane | 3184 | 1.95 (heavier than air) |
| Butylene (Butene) | 3077 | 1.94 |
| Carbon Monoxide | 323 | 0.97 |
| Carburated Water Gas | 550 | 0.63 |
| Coke oven | 570 | 0.40 |
| Digester (Sewage) Gas | 690 | 0.80 |
| Ethane | 1783 | 1.06 |
| Hydrogen | 325 | 0.07 |
| Manufactured Gas | 500 - 600 | |
| Methane | 1011 | 0.55 |
| Natural Gas | 950 - 1150 | 0.660 - 0.708 (lighter than air) |
| Propane | 2504 | 1.77 |
| Propane-Butane Mix | 2500 - 3200 | |
| Propylene (Propene) | 2332 | 1.45 |
