In a propane-operated flamethrower, the gas is expelled through the gun assembly by its own pressure and is ignited at the exit of the barrel through [[piezo ignition]].

Liquid-operated flamethrowers use a smaller tank with a pressurized gas to expel the flammable liquid fuel. The propellant gas is fed to two tubes. The first opens in the fuel tanks providing the pressure necessary for expelling the liquid.<ref>{{cite web|last=Harris |first=Tom |url=http://science.howstuffworks.com/flamethrower3.htm |title=HowStuffWorks "How Flamethrowers Work" |date=25 October 2001 |publisher=Science.howstuffworks.com |access-date=2010-03-04}}</ref> The other tube leads to an ignition chamber behind the exit of the gun assembly, where it is mixed with air and ignited through piezo ignition. This pre-ignition line is the source of the flame seen in front of the gun assembly in movies and documentaries. As the fuel passes through the flame, it is ignited and propelled towards the target.
