Check out a Thesis by Grant Ballard-Tremeer which promotes the use of vent hoods for the testing and evaluation of rural cooking stoves. http://www.ilink.co.za/~grantt/

After reading his thesis I was motivated to try and apply it to the testing of the One-Can Charcoal Making stove.

This afternoon I tested a scaled up version of the venturi burner.
The idea being to produce charcoal on a "viable" scale without the
