Re: Down draft stoves are grate!

["Ron Larson" <ronallarson@qwest.net>]

Rogerio, Piet, et al

    I agree with Piet (not to promote the DDS) - if we limit ourselves to
the style of fuel feeding described by Piet and Khan.

    But I think there is plenty of evidence from the gasifier community
(Reed, Das,....) that downdraft works well for pellets and gas production.
I also think that we should heed the good words offered by Dean Still on
some advantages they have found with DD.

    But my main point is that I can find no-one doing stove R&D
incorporating both DD and air control (implying a closed batch load of fuel)
with a small controllable port for primary air control).  This looks
potentially attractive and I hope someone can report on whether it has some
advantages.

    Perhaps yours is the group to give it a try, since the DD stove
described by Piet is rather close to your own designs as I understand them
(meaning a large metal plate and a chimney).
