Re: Flame arrestor?
A 'flame arrestor' works by providing a heat sink to reduce the temperature of the fuel/oxidant mix below the spontaneous ignition temperature. The flame cannot travel through or across it without cooling below that critical point and stopping the chemical reaction.
If you think about it, the burners in a water heater, furnace, BBQ, kitchen stove all work the same way. A mix of flammable fuel/air is fed into them but the flame stays outside the burners, not traveling back up into the feed. The metal absorbs heat, preventing the flame front from traveling back up to the source.
