For example, located below the uppermost air supply passage 81,
Since the air is also introduced into the air supply passage 83, the waste (not shown) burns, and the temperature in the combustion chamber 3 becomes high, so that the plastic contained in the waste (not shown) melts and moves downward. Even if the air flows near the opening 4 facing the combustion chamber 3 where it is located, air blows out from the opening 4 and the intrusion of the molten plastic into the opening 4 can be prevented.

果を奏する。 The method for cooling incinerated ash according to the present invention is a method for burning waste in which waste is stored in a combustion chamber in a batch type furnace and the waste is sequentially burned from the upper part to the lower part. A small lump is spread all over the bottom of the combustion chamber.
Stuffing, placing the waste on top of the blob,
The positions the outlet of the air supply passage, the normal combustion air by is sequentially burned from the top of the waste on the waste, the waste is incinerated by combustion, the waste of unburned
When the remaining amount of waste is reduced and at the end of the incineration of the waste, the air from the air outlet of the air supply passage is connected to the small lump.
Since the unburned waste is supplied from below the waste through a gap with the small lump to incinerate the waste, and the ash generated by the incineration is forcibly cooled, the waste is recycled.
Of Waste Combusted from Top to Bottom
In the method, the time required for combustion is longer than that of grate combustion.
However, when the remaining amount of unburned waste becomes low,
Unburned by supplying air from below the object and taking into account grate combustion
Quickly burns the waste and incinerates when the waste is incinerated
Forcibly cool the ash and quickly remove it from the combustion chamber
Air from the outlet of the air supply pipe
Through the gap between the nodules and the waste
Waste and air supply passage
A small lump is interposed between the air supply passage and the air supply passage.
It is possible to prevent waste from clogging at the exit.
