いた。
Conventionally, as shown in FIG.
c, the lid body 13 is inserted into the opening formed in the furnace bottom wall portion, the monolithic refractory 19 forming the furnace bottom surface 1a is provided inside the lid body 13, and the furnace bottom surface 1a is The discharge passages 12 were arranged to be connected smoothly.
しかし、炉内補修等のために、炉全体を徐冷し
た後蓋体１３を下方に抜出して炉底部１ｂを開放
する際、不定形耐火物１９が焼結すると共に、徐
冷によつて極めて硬くなつた固化スラグ２０が焼

を下方から人為的に鉄棒等で突崩して落下させる
作業が必要となり、その作業が困難かつ危険であ
る。
However, when the lid body 13 is pulled out downward to open the furnace bottom 1b after the entire furnace has been slowly cooled for repairing the inside of the furnace, the monolithic refractory 19 is sintered and extremely Since the hardened solidified slag 20 sticks to the entire upper surface of the sintered monolithic refractory 19, the monolithic refractory 19 remains even after the lid 13 is removed.
And the solidified slag 20 remains like a lid, so the remaining monolithic refractory 19 and solidified slag 20
It is necessary to manually collapse the concrete from below using an iron rod or the like, and this work is difficult and dangerous.
また、蓋体１３を取付けるに際して、作業者が
マンホールから炉内に入り、不定形耐火物１９を
内張りしなければならず、この作業も困難かつ危
険であり、作業性や安全性の面で改良の余地があ
つた。 In addition, when installing the lid body 13, a worker must enter the furnace through a manhole and line the furnace with the monolithic refractory 19, which is difficult and dangerous, and improvements should be made in terms of workability and safety. There was room for.
本考案の目的は、炉底部を開放する作業及び閉
塞する作業のいずれも容易かつ安全に行えるよう
に、かつ、そのために操業中に炉のトラブルが生
じやすくなる不都合が無いように、蓋体を改良す
る点にある。 The purpose of this invention is to make it possible to easily and safely perform both the work of opening and closing the bottom of the furnace, and to avoid the inconvenience of causing trouble with the furnace during operation. There are points to improve.
〔問題点を解決するための手段〕
本考案の特徴構成は、炉底部を開放する蓋体
を、その炉底部に接続した溶融廃棄物の排出路を
囲む炉壁の少なくとも下部、及び、前記炉底部を
囲む炉壁で形成し、前記蓋体と炉本体との接合部
を炉内底面よりも上方で、前記高温炉床に燃焼用
空気を供給するノズルよりも下方に配置したこと
にあり、その作用効果は次の通りである。[Means for Solving the Problems] The characteristic configuration of the present invention is that a lid body that opens the furnace bottom is attached to at least the lower part of the furnace wall surrounding the molten waste discharge path connected to the furnace bottom, and the lid that opens the furnace bottom. It is formed by a furnace wall surrounding the bottom, and the joint between the lid and the furnace body is arranged above the bottom surface of the furnace and below the nozzle that supplies combustion air to the high-temperature hearth, Its effects are as follows.
つまり、蓋体を外すと、炉底部と排出路に残つ
ていた溶融廃棄物が大気により急冷され、固化ス
ラグがもろくなつて容易に除去できるようにな
り、また、その除去作業を蓋体の上方から容易か
つ安全に行える。
In other words, when the lid is removed, the molten waste remaining at the bottom of the furnace and the exhaust channel is rapidly cooled by the atmosphere, and the solidified slag becomes brittle and can be easily removed. This can be done easily and safely from above.
また、蓋体を取付けるに際し、炉内底面と排出
路の下部が蓋体で完全に形成されているから、蓋
体を取付けた後で炉内に立ち入つての不定形耐火
物の内張り作業が不要になつた。 In addition, when installing the lid, the bottom of the furnace and the lower part of the discharge channel are completely formed by the lid, so there is no need to enter the furnace and line it with monolithic refractories after installing the lid. It became.
さらに、接合部を炉内底面よりも上方に配置し
てあるから、操業中に溶融廃棄物が接合部に流入
して、接合部のシール材が高温の溶融廃棄物との
接触で損傷されるトラブルの危険性が無い。 Furthermore, since the joint is located above the bottom of the furnace, molten waste may flow into the joint during operation, and the sealing material at the joint may be damaged by contact with the high-temperature molten waste. There is no risk of trouble.
特に、接合部をノズルよりも下方に配置してあ
るから、蓋体の脱着に際して、一般に炉周方向に
多数が分散配置されるノズルに対する配管系を分
解したり接続する面倒な作業が必要で無く、この
面からも蓋体の脱着作業を容易迅速に実行でき
る。 In particular, since the joint is located below the nozzle, there is no need to disassemble or connect the piping system for the nozzles, which are generally distributed in large numbers around the furnace circumference, when attaching and detaching the lid. Also from this point of view, the work of attaching and detaching the lid body can be carried out easily and quickly.
その結果、炉底部の開放作業及び閉塞作業のい
ずれも容易かつ安全に行えるようになり、操業中
