Hummmm

Ok.... lets start with the real basics...

You should experiment with a test tube and some wood in it...

Heat it with a stopper in it (high temp silacone prefered)(or ceramic or
 alumina or graphite or etc.)

with a glass tube for venting.... then (use safety goggles) light the output
 occasionally

You will note that at various temperatures you get off components that burn...

you might also collect and fractionate the compounds coming off (sure you can
figure out how to do that n..no?) and then see which ones burna dn at what
 temperatures they will turn to compustable fumes rather than solids...

crude testing ..but adequate for stove design initially....

What needs to be done then is several things...

First the reductant candidate (wood) must be heated to give off its reducable
compuinds.... or elements...

then you send these through a series of baffles and vants designed to keep a
 stable temperature range and oxident - reductant ratio in each baffle series
 to make sure that the combustion is full in each stage....

temeratures are VERY high in such stoves (usually white hot) but combustion of
 the wood is VERY complete with little particulate matter... and what is
 emitted is easy to trap in "tornado" style traps.... the output temperatures
 are also very low... if done right you can run the output exhaust out through
nothing more complex than plastic PVC piping as it is usually no warmer than
 about 120F max

The goal is to

seperate into murnable components

burn each component as hot and as fully stociometrically as possible

baffle outputs to seccor as much energy from the remainging gasses as possible

use centrifical speeration ont he remaining output gasses and matter to
 seperate out the bulk of the contrained particulate matter

*************************


Feel free to ask many mroe specific questiosn of you like...


shoulds we work through the process of designing and dimensioning and
 ...engineering such as stove here?

might be fun?
