How hot is hot? Prolly about as hot as a masonry stove would get,
~1,200*F (?). www.tempcast.com or
http://www.vtbrickoven.com/masonry/masonry.html
Not the "hot" of a standard wood burner.
You might could get away with mixing the catalyst/soap/alcohol
("glycerin layer") with WVO, SVO or WMO (waste motor oil,
hydraulic and transmission fluid) in a furnace or boiler
specifically designed for WMO. The combustion in these units is
very efficient due to the hp air input (www.cleanburn.com or
other types).
You could also prolly use the "paste log" mentioned below in a
downdraft wood gasifier
