Combustible Gases

Common combustible gases include methane, propane, butane, hydrogen, and acetylene, which can ignite or explode when mixed with air and exposed to a source of ignition.
Here’s a more detailed list:
Common Combustible Gases:
Methane (CH4): Natural gas
Propane (C3H8):
Butane (C4H10):
Hydrogen (H2):
Acetylene (C2H2):
Ethane (C2H6):
Ethylene (C2H4):
Carbon Monoxide (CO):
Hydrogen Sulfide (H2S):
Ammonia (NH3):
Other Gases:
Iso-butane (i-C4H10):
Ethanol (C2H6O):
Methanol (CH3OH):
Propylene (C3H6):
Pentane (C5H12):
Silane (SiH4):
Important Considerations:
Flammability Limits:
The concentration of a combustible gas in air must be within a specific range (Lower Explosive Limit – LEL and Upper Explosive Limit – UEL) for combustion to occur.
Combustion Process:
Combustion requires a fuel (combustible gas), an oxidizer (oxygen), and an ignition source (heat).
Safety:
Combustible gases are dangerous and require careful handling and storage.
Detection:
Gas detectors are used to monitor the concentration of combustible gases in the air and trigger alarms when levels exceed safe limits.
