Interesting question..

Putting grooves in the sides of the arrow, to protect some of the flame from being blown-out, might be a useful improvement..

The people identifying that oil/petrochemicals burn are right, but you want to have the viscosity of the fuel be such that it'll burn easily ( low-viscosity, vaporizes easily ) and it won't be blown-off ( high viscosity, doesn't burn easily ), so then you have to solve your airspeed, to optimize the fuel for that airspeed..

So, a fuel which may work well on a 20lbs bow might not work well on a 60lbs draw bow..

Bullets apparently just use white phosphorous in their tails ( tracers ).
