Firewood burning is an old skill, and the difficulty of burning a kiln is quite high. The success or failure of the firewood works depends on the relationship among soil, fire, firewood and kiln. The architecture of a wood kiln is generally divided into four sections: fire chamber, kiln chamber, chimney and flue. The principle of kiln burning is as follows: the heat, ash and flame generated by the combustion of wood in the fire chamber act and effect on the ceramic blanks in the kiln chamber, and are discharged by the white smoke. The design of the kiln is therefore focused on: combustion (including temperature rise and heat preservation) is facilitated; the adhesion of fire and ash on the green body is facilitated; the exit path of the fire (side flame, back flame or direct flame). The existing firewood kiln has some problems: in the process that flame and flue gas rise from top to bottom, each corner of furnace chamber can not be fully covered, the effect of generating the ash glaze is not good, the heat preservation and cooling effect of kiln are not good, the inlet port of air chamber is easily blocked by falling ash, the temperature uniformity of horizontal cross section can not be realized in the hole arrangement of inhaling of furnace chamber bottom, in view of this, the present case produces from this.
