【考案の詳細な説明】
この考案は、おもにアルミニウム等の軽金属を
溶解する際に使用される輻射熱を利用する燃焼炉
に関する。[Detailed Description of the Invention] This invention relates to a combustion furnace that utilizes radiant heat, which is mainly used when melting light metals such as aluminum.
従来のこの種の燃焼炉には、炉体の壁に煙道口
が開放してあつて、煙道を通じてガスを排出する
ようになつているが、この煙道口からガスと共に
熱が排出することは勿論、煙道口からの輻射熱が
期待されず、単に煙道口の断面積に限らずその周
囲壁の熱までも放出されることから、輻射熱量の
減少を余儀無いものとされていた。 Conventional combustion furnaces of this type have a flue opening opened in the wall of the furnace body, and gas is exhausted through the flue, but heat is not exhausted together with the gas from this flue opening. Of course, radiant heat from the flue opening was not expected, and since heat was radiated not only from the cross-sectional area of the flue opening but also from the surrounding walls, the amount of radiant heat had to be reduced.
この考案の目的は、以上の従来の炉に見られる
輻射熱量の減少を食い止め、煙道口よりの輻射熱
が得られ熱の有効利用を向上し得る輻射熱を利用
する燃焼炉を提供することにある。 The purpose of this invention is to provide a combustion furnace that utilizes radiant heat, which can prevent the decrease in the amount of radiant heat seen in the conventional furnaces, obtain radiant heat from the flue opening, and improve the effective use of heat.
この考案の構成は、炉体壁に開放された煙道口
前に、輻射率の大きい材質で形成したスクリーン
を炉体壁より間隔をあけ且つ煙道口を覆う状態に
固定したもので、ガスはスクリーンと炉体壁の間
隔より煙道口へ誘導されて放出するが、スクリー
ンから輻射熱が発生し、該熱を有効に利用すると
共に、炉内の熱分布を均一化するものである。 The structure of this device is that a screen made of a material with high emissivity is fixed in front of the flue opening that is open to the furnace wall, with a gap from the furnace wall and covering the flue opening. The screen generates radiant heat, which is guided to the flue by the gap between the screen and the furnace wall, and is used to effectively utilize the heat and even out the heat distribution within the furnace.
以下、この考案を実施例によつて説明する。第
１図に示す例は、炉本体１の天井壁２に煙道口３
を開放し、これに連続して煙道４が設けてある。
この炉本体１において、煙道口３の前に煙道口３
の断面積より大きいスクリーン５を、天井壁２よ
り突出した数本の支持ボルト６で支承しナツト７
で締め付けてあり、しかもスクリーン５は天井壁
２より間隔をあけて、スクリーン５と天井壁２間
にガスの煙道口３への誘導間隔を設けたものであ
る。更にスクリーン５は輻射率が大きく熱容量の
小さい材質、例えばセラミツク板で形成してあ
る。 This invention will be explained below using examples. In the example shown in FIG.
is open, and a flue 4 is provided continuously to this.
In this furnace body 1, a flue opening 3 is placed in front of the flue opening 3.
A screen 5 larger than the cross-sectional area of is supported by several support bolts 6 protruding from the ceiling wall 2, and
Moreover, the screen 5 is spaced apart from the ceiling wall 2, and a gap is provided between the screen 5 and the ceiling wall 2 to guide gas to the flue port 3. Furthermore, the screen 5 is made of a material with high emissivity and low heat capacity, such as a ceramic plate.
第２図に示す例は、煙道口３を炉本体１の側壁
８に設けた場合であつて、この煙道口３に前述と
同様の構造をもつてスクリーン５を設けたもので
ある。 In the example shown in FIG. 2, a flue opening 3 is provided on the side wall 8 of the furnace body 1, and a screen 5 having the same structure as described above is provided on the flue opening 3.
尚、図中９はアルミニウム等の被加熱物を示し
ている。 Note that 9 in the figure indicates an object to be heated such as aluminum.
この考案による輻射熱を利用する燃焼炉によれ
ば、煙道口前をスクリーンで炉本体の壁より間隔
をあけて覆つてあるので、従来煙道から放出され
ていた熱をスクリーンで止め、その熱を輻射熱と
して利用されることから、熱利用の有効性が向上
され、省エネルギー化を図ることが出来るもので
ある。 According to this combustion furnace that uses radiant heat, the front of the flue is covered with a screen at a distance from the wall of the furnace body, so the screen stops the heat that was conventionally emitted from the flue, and the heat is Since it is used as radiant heat, the effectiveness of heat utilization is improved and energy savings can be achieved.
