   A really simple way to get cleaner burns from an unmodified heating stove is
to do top-down burns. Load the big logs into the bottom, kindling and paper at
the very top, let burn down totally to ash and start over.

   Don't just add a heat exchanger, make it a secondary burning chamber as
well. Put a 5 or even 10 gallon drum on top of the stove with adjustable air
inlets where the smoke first comes into the stove. Maybe add a small blower
to those inlets as well. Or, if your stove already has a secondary burning
chamber, try adding a very small blower to that secondary air inlet.
