この発明は炉内の温度が均一で熱エネルギー効率のよい
バッチ式の焼成炉に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a batch-type firing furnace that has a uniform temperature inside the furnace and is highly efficient in thermal energy.
従来例にかかるバッチ式の焼成炉の代表的なものを第１
図および第２図に示した。The first typical example of a conventional batch-type firing furnace is
and Fig. 2.
図にもとづい°〔その構造を説明すると、炉の本体１の
内壁に、その壁面に沿ってヒータ２が配設され”Ｃおり
、本体１の空間に被焼成品３を設置し°Ｃ焼成を行うよ
うに構成されている。Based on the figure, the heater 2 is installed on the inner wall of the furnace main body 1 along the wall surface, and the product 3 to be fired is placed in the space of the main body 1 and fired at °C. is configured to do so.
したがって、被焼成品５はその周囲にあるヒータ２の熱
により加熱され、焼成されることになる。Therefore, the product to be fired 5 is heated by the heat of the heater 2 around it and is fired.
ところが、ヒータ２が壁面に沿って配置される構造罠な
っていることから、本体１の空間を太きくすれば、それ
だけ被焼成品３に対する加熱温度のバラツキが生じるこ
とになる。また、多くの被焼成品３を空間に充填すると
、ヒータ２に近い被焼成品３のみが高温に曝されること
になる。一方、ヒータ２かも遠い位置、つまり空間の真
ん中に近い被焼成品３は焼成に十分な温度に加熱されな
くなシ、焼成のバラツキを発生させるととＫなる。However, since the heater 2 has a trap structure in which it is arranged along the wall surface, the wider the space in the main body 1, the more variation in heating temperature for the product to be fired 3 will occur. Moreover, if many products 3 to be fired are filled in the space, only the products 3 to be fired near the heater 2 will be exposed to high temperature. On the other hand, the article 3 to be fired at a position far from the heater 2, that is, close to the center of the space, will not be heated to a temperature sufficient for firing, which will cause variations in firing.
さらに１ヒータ２はその半分が炉壁に面しＣいるため、
ヒータ２からの輻射熱の％は被焼成品３を加熱するため
に利用されず、熱エネルギーの利用効率の悪い構造とな
り゛〔いる。Furthermore, half of heater 2 faces the furnace wall, so
% of the radiant heat from the heater 2 is not used to heat the product 3 to be fired, resulting in a structure with poor thermal energy utilization efficiency.

１内の温度分布を調べたところ、−１４図〜第６図のよ
うな温度分布を示すことが明らかとなった。In the conventional batch-type firing furnace shown in FIG. When we investigated the temperature distribution inside the furnace main body 1 at each line "H, b-bg, and C-a in Figure 6, it became clear that the temperature distribution showed the temperature distribution as shown in Figures -14 to Figure 6. .

傍が高温であり、１２９９〜１３０ａｔの温度分布領域
に入るのはｂ−ｂｍの平面よりやや上にあることが判明
した。In other words, as is clear from Figures 4 to 6, the variation in temperature distribution on the a-a line plane is ±5°C, and b
-The variation in temperature distribution on the plane of line b is ±Z5″C
In addition, the variation in temperature distribution in the plane of Ic c - c ls was ±12.5'C. It was also found that the temperature near the furnace wall was high, and the temperature distribution region of 1299 to 130 at was slightly above the b-bm plane.

あシ、電力消費量も多いものであった。In this way, in conventional batch-type firing furnaces, there are variations in the temperature distribution within the furnace, and even if you take each plane in the furnace, you can see variations in the temperature distribution within that plane. In addition, in conventional firing furnaces, the temperature inside the furnace is set at 1300°C, that is, the temperature at the center of the furnace is set at 1300°C. 00
t, the power consumption per hour was approximately 42xW, which was a large amount of power consumption.
したがって、この発明は炉内の温度分布が均一なバッチ
式の焼成炉を提供することを目的とする。Therefore, an object of the present invention is to provide a batch-type firing furnace in which the temperature distribution inside the furnace is uniform.
また、この発明・よエネルギー効率がよく、熱損失の少
