Dear Roger What do you think of the MTS as a sawdust burner?
Rajan: if I get a chance I will test it....wait, I don't have one here! Oh. Well, next time I get one I will be able to test it with crushed 5mm pellets which won't burn in just about any stove. What a terrible fuel. As Christa mentioned, the stove has a circular rim full of fuel that needs to be tapped to feed more fuel in. At the same time the vibration causes the ash to fall out of the bottom. Depending on the way the bottom air enters (i.e. Roger's original from Gambia or my version of it) the amount of char is quite different, mixed in the ash that falls out. So it can be made to be a pyrolyser or a gasifier depending on the handling of primary air entry. It requires much more attention than an open fire with large fuel because if you don't pay some attention to the fuel level it will eventually burn through the ring of fuel at some point which lets in way too much air. That shows the fuel needs to be relatively dense to choke the airflow through it, and that the fire is operating in a negative pressure zone . Both are advantageous. Paul in Vietnam recently added a secondary air preheating tube passing through the pyrolysing zone. The MTS has the same arrangement except Roger uses two tubes. I tried it with one and it was also successful. There is every reason to expect that the MTS layout will burn sawdust properly if the lack of air flowing through the fuel can be compensated for by increasing (for example) the primary air supply at the bottom. What would be difficult would the ability to burn (well) a wide range of sawdust from shavings to powder. The air supply would be continuously changing so gasification would be hard to make constant.

Can this stove burn saw dust also ?
