[0003]

[Problems to be Solved by the Invention] When the incinerator completes one day of incineration of waste materials, the incinerator is left as it is,
The next morning, before the start of new incineration work, the incineration ash in the furnace is removed, but at this time, a large amount of charcoal or extinguishing charcoal remains, which is buried in the incinerated ash. This is because the waste material that is being incinerated is buried in the incinerated ash, the amount of oxygen supplied is reduced, and the combustion speed becomes slow.

This presents a difficult problem to dispose of incinerated ash. When the container is transferred from the incinerator to a container for disposal and transportation, the fire remains and the container will not only heat up forever, but the unburned charcoal will not burn any more actively. Even if you manage to extinguish the fire of the unburned charcoal somehow, it will remain as extinguished charcoal, and not only ash, but a large amount of waste. This final waste (basically ash)
However, the increase in quantity is a serious problem because it must be disposed of at a managed disposal site at a high cost per cubic meter.

In view of the above-mentioned problems, the present invention is capable of accelerating post-combustion, which is contained in combustion ash from an incinerator for incinerating industrial waste such as waste materials of house dismantling, and It is an object of the present invention to provide an apparatus capable of selecting foreign matter.
