与えたことを特徴とする。Means for Solving the Problems: The present invention is intended to solve the above problems, and includes providing a heat generation source and a heat storage body that supply heat to the exhaust flow path, and an air system that introduces air into the exhaust flow path. The present invention is characterized in that an introduction system is provided, and the heat generation source is given a heat generation capacity to raise the temperature of the reducing high temperature gas discharged from the firing space in the furnace to a temperature equal to or higher than the combustion start temperature.
作用: 陶芸炉の焼成作業は第4図に示す如く、時点t、。Action: The firing operation in the pottery furnace begins at time t, as shown in FIG.
t2間の「あぶシだき」、時点t2 、 t3間の「攻
めだき」、時点℃S + t4間の「ねらし」に分けら
れ、燃料の供給は時点t4において断たれる。焼成作業
には酸化性雰囲気の下において行われる酸化焼成と還元
性雰囲気の下において行われる還元焼成とがあり、還元
焼成は時点t2+ tS間の「攻めだき」を雰囲気を還
元性にして行うものである。It is divided into "abusing" between t2, "attacking" between time t2 and t3, and "aiming" between time ℃S + t4, and the fuel supply is cut off at time t4. Firing operations include oxidizing firing, which is performed in an oxidizing atmosphere, and reduction firing, which is performed in a reducing atmosphere.Reduction firing is performed in a reducing atmosphere during the "aggressive" period between time t2 + tS. It is.
上記本発明による陶芸炉は灯油バーナを使用する従来の
陶芸炉の欠点(還元焼成を行うときに黒煙および煤を発
生するという欠点)を伴わないもので、このものにおい
ては発熱容量を充分大きくして排気流路内に設けられた
熱の発生源が排気流路への空気の供給系と共働して排気
を燃焼状態に移行させ、それによって黒煙および煤の発
生が起らないようにする。すなわち、本発明による陶芸
炉の排気流路は排気を燃焼させる燃焼装置の一要素とさ
れてAるのである。The pottery furnace according to the present invention does not have the drawbacks of conventional pottery furnaces that use kerosene burners (such as generating black smoke and soot during reduction firing), and has a sufficiently large heat generating capacity. The heat generation source provided in the exhaust flow path cooperates with the air supply system to the exhaust flow path to move the exhaust gas into a combustion state, thereby preventing the generation of black smoke and soot. Make it. That is, the exhaust flow path of the pottery furnace according to the present invention is considered as one element of the combustion device that burns the exhaust gas.
