Title: Smoke-incinerating woodstove

Patent ·
OSTI ID:6719038

A stove is described for the efficient combustion of wood comprising: a pyrolitic conversion chamber for receiving the wood fuel during a refueling period, means for generating a controlled draft of air through the fuel in the chamber and means for heating the fuel in the chamber in the presence of the controlled draft of air to generate a volatiles stream of water vapor and other volatile components, and an essentially volatiles free wood fuel; a combustion region separate from the pryolitic conversion chamber having a means for generating a controlled draft of combustion air therethrough; means for transferring the essentially volatiles free wood fuel from the pyrolitic conversion chamber to the combustion region; a temporary storage device including condensing means for separating the volatiles stream into a condensable fraction which includes the water vapor and an uncondensed fraction. It also includes temporary storage means for temporarily storing the condensable fraction during an initial period following refueling when the combustion region cannot efficiently incinerate the condensable fraction as fast as the condensable fraction is being generated; first fluid conduit means for transferring the volatiles stream from the pyrolitic conversion chamber to the temporary storage device; and second fluid conduit means for transferring the uncondensed fraction from the temporary storage device to the combustion region.
