乾燥した灰を溶融炉に投入するように構成していた。Conventionally, the municipal waste incinerator and the melting furnace are installed separately, and a separation device is used to remove incombustible materials such as electrical appliances and kitchen utensils from the wet ash from the ash extruder of the municipal waste incinerator, and A dryer was installed to dry the ash, and the ash dried by the dryer was put into a melting furnace.
そして、溶融炉で発生する未燃ガスを溶融炉の内部で後
燃焼するように、溶融炉を高いものに形成していた。The melting furnace is made high so that the unburned gas generated in the melting furnace is post-combusted inside the melting furnace.
しかし、大型の灰押出機、分離装置、ドライヤが必要で
あり、かつ、溶融炉が大型化するために、設備費が膨大
になると共に、設備の維持管理経費が高くなる欠点があ
った。However, since a large ash extruder, separator, and dryer are required, and the melting furnace is enlarged, there are disadvantages in that the equipment cost is enormous and the maintenance and management costs of the equipment are high.
本発明の目的は、灰押出機、分離装置、ドライヤを不要
にすると共に、溶融炉を十分に小型化して、設備費及び
維持管理費を大幅に節減できるようにする点にある。An object of the present invention is to eliminate the need for an ash extruder, a separator, and a dryer, and to sufficiently downsize the melting furnace so that equipment costs and maintenance costs can be reduced significantly.
本第１発明の特徴構成は、都市ゴミ焼却炉の灰落下路に
高温炉床型式の溶融炉を、灰シュート兼溶融炉用排ガス

用は次の通りである。The characteristic structure of the first invention is that a high-temperature hearth type melting furnace is directly connected to the ash fall path of the municipal waste incinerator by a communication path that serves as an ash chute and an exhaust gas path for the melting furnace. It is as follows.
都市ゴミ焼却炉の灰落下路からの灰を連通路により溶融
炉に直接的に供給するから、前述の従来技術で必要とし
ていた大型の灰押出機、分離装置、ドライヤを不要にで
き、設備費及び維持管理費を大幅に節減できる。Since the ash from the ash fall path of the municipal waste incinerator is directly supplied to the melting furnace through the communication path, the large ash extruder, separator, and dryer required in the conventional technology mentioned above can be eliminated, and equipment costs can be reduced. And maintenance costs can be significantly reduced.
また、溶融炉からの排ガスを連通路により都市ゴミ焼却
炉に送るから、溶融炉で発生した未燃ガスを都市ゴミ焼
