ABSTRACT:
A burning method and apparatus, using solid type fuel, comprising a combustion chamber in combination with a heat-extractor labyrinth chamber through which an artificial draft is generated mechanically. The artificial draft can be generated by intake and exhaust fans and/or blowers operating at accurately controlled speeds.
In a specific stove-type embodiment, the draft-flow within the combustion chamber is utilized by a reversal of its flow pattern for either conventional up-draft burning, or preferably, for down-draft burning, with the gases exiting through the heat extractor compartment at close to ambient temperature and a short horizontal flue into the atmosphere. In this embodiment, the intake fan also serves to distribute usable heat from the surfaces of the combination and heat extractor compartments.
