Always a problem with charcoal gasifiers.
Alcohols work, but are flamable and exensive. Antifreeze is not a optimal solution either, its poisonous and not cheap.
The other day l was dealinig with some rock clearing, some of you guys might connect how ammonium nitrate fits in the story. Anyway, ammonium nitrate is a common fertiliser but not everyone knows is a wery soluble metal-less salt and is wery oxidising. Bingo for us.
So, if we mix a few % of AN with the water, the water doeseng freeze and as the AN breaks down in extreme heat it decomposes in to H2O and N2O, allso called nitros. Thats right, THE nitros that gets used as a power booster in sports cars. It aids combustion by adding aditional O2 in the mix, wich means only less N2 in our woodgas, richer gas.
It might be a way to kill 2 birds with one stone. I will eventualy try this but l hope someone else does this sooner and reports the resaults.
