Ok so let me geet this strait, the two methol and ethol are pretty much the same. One is a bit hotter burning.
From Brad: Methyl hydrate = methanol / wood alcohol
denatured alcohol = ethanol / grain alcohol
IIRC, ethanol (denatured alcohol) burns a little hotter (more BTU/lb)
From RichH: Methyl Hydrate is simply another 'tech name' for wood alcohol or methanol
The High Heat Value (HHV) for methanol is ~10,000 BTU/lb.; for ethanol ~13,000 BTU/lb.
Denatured Alcohol is simply ethanol with a wee bit of methanol added to make it 'poisonous'.
The use of the term methyl hydrate instead of wood ALCOHOL or methyl ALCOHOL is to lessen the chance of alcohol addicted persons from mistakenly drinking it and going blind or dying.
So what can I use in my old Coleman stove? It looks like this one. Just not as clean, and with a few scorch marks on the wind protector things...
