Since my post about pyrolyzing biomass stoves, I’ve been trying to understand how the Lucia Stove works. A lot of the pyrolyzing stoves are “TLUDs” (Top Lit Updraft). My understanding was that TLUDs really only work well in batch mode, while the Lucia Stove promises that more fuel can be added during a burn run. Unfortunately the WorldStove site and YouTube Videos contain just enough information to confuse me, so I went digging around the Stoves Mailing list and finally found what I was looking for, in an explanation by Nat Mulcahy to some questions posed by Clement Davis.
