A husk burning furnace having a husk smoke-burning chamber formed by an inner peripheral perforated wall defining a pot-shaped primary gas burning chamber and an outer peripheral perforated wall surrounding the inner peripheral perforated wall. Means are provided to feed the husk particles into the smoke-burning chamber from the lower side of the latter in a floating manner where they are smoke-burnt to become smoke-carbonized husk particles, while generating unburnt gas. The smoke-carbonized husk particles are taken out of the furnace while the unburnt gas is introduced into the primary gas burning chamber so as to be burnt in the primary gas burning chamber. The gas together with flame is introduced further into a secondary gas burning chamber connected to the upper end of the inner peripheral perforated wall to generate colorless hot gas containing no substantial quantities of dust particles. Meanwhile, the smoke-carbonized husk particles are suitably discharged to the desired place.
A husk burning furnace characterized by comprising, in combination, an inner peripheral perforated wall defining a pot-like cylindrical primary gas burning chamber provided at its upper end with an opening constituting a hot gas outlet, an outer peripheral perforated wall surrounding said inner peripheral perforated wall and defining therebetween a conically annular husk smoke-burning chamber provided with a husk supply port opening at a lower part thereof, a husk supplying device connected to said husk supply port and adapted to forcibly move husk particles upwardly to feed and supply the latter, a secondary gas burning chamber connected to the upper end of said hot gas outlet, a hot gas discharge port communicated with said secondary gas burning chamber, a smoked-carbon discharge port adapted to upwardly discharge the husk particles smoke-carbonized in said smoke-burning chamber, and an outer cylindrical wall accommodating the above-mentioned constituents.
