Cooling water is supplied from the water supply tank 12 into the water cooling jacket 11. The cooling water can prevent the combustion temperature in the combustion chamber 10 from excessively rising. Water boiling in the water-cooled jacket 11 due to the heat of combustion of the incinerated material 9 evaporates from an upward steam discharge cylinder 13 a provided in a circulation surge tank 13 communicating with the inside of the water-cooled jacket 11. Cooling water is replenished from the water supply tank 12 into the water cooling jacket 11 by an amount reduced by evaporation.

The ceiling 11 of the water-cooled jacket 11
“a” is inclined upward toward the surge tank 13 so as not to cause air accumulation.

The incinerator 2 is provided with a carry-in port 14 for the incinerated material 9 on the left side in the horizontal direction. The size of the carry-in port 14 is the same as that of the large flat incinerated material 9 described above.
Is large enough to pass, in its original form, horizontally. In the illustrated example, the laterally left portion of the incinerator 2 is fully opened to serve as the carry-in port 14. The carry-in port 14 is also used as an outlet for taking out cinders such as ash and charcoal remaining in the combustion chamber 10 after combustion.

The carry-in port 14 of the incinerator 2 can be freely opened and closed by carrying-in doors 15 and 15. In the illustrated example, two sliding doors that can move horizontally in the approaching and separating directions are adopted so that the carrying-in port 14 can be fully opened.

The incinerator 2 is provided with a heat-resistant transport means for slidably supporting the incinerated material 9 carried in from the carry-in port 14 in the combustion chamber 10. In the illustrated example, two roller devices 21 made of heat-resistant steel and provided with a large number of rollers 20 are used as the transport means. The roller device 21 is disposed in front and rearward and parallel to the left and right horizontal loading direction of the incineration material 9 from the loading port 14. The two roller devices 21 and 2 in the combustion chamber 10
The arrangement of 1 is considered so that the incinerated material 9 can be supported and transferred in a well-balanced manner.

Next, the reburning furnace 5 will be described.
The reburning furnace 5 is an upwardly cylindrical member having a reburning chamber 22 therein, and the chimney 8 is continuously provided at an upper portion thereof, and a door 5a for internal inspection is provided on a side portion thereof. It is attached. The reburning chamber 22 includes the combustion gas transfer device 7.
As a result, the combustion gas generated in the combustion chamber 10 is introduced through the flue 4. The reburning chamber 22 is supplied with air for reburning together with the combustion gas. The combustion gas reacts with the reburning air and is completely burned by the action of a burner 23 as a reburning flame supply device provided in the reburning furnace 5 to become a clean exhaust gas. From the atmosphere.

Referring mainly to FIG. 4, the combustion gas transfer device 7, the main combustion air supply device 3, and the recombustion air supply device 6 will be described. In the illustrated example, some of these three devices 7, 3, 6 are integrated with each other.

The combustion gas transfer device 7 is connected to a blower 25 which is drivingly connected to an electric motor 24 as a power source, and communicates with a discharge port 26 of the blower 25 so as to communicate with the reburning chamber 22 in the flue 4. Air line 2 for creating negative pressure that opens to the side
7 is provided.

A main pipe 28 is connected to the discharge port 26 of the blower 25, and three branch pipes 27, 29, and 30 extend from a tip 28a on the downwind side of the main pipe 28. ing. One of them is the negative pressure generating air line 27. The negative pressure generating air line 27 rushes into the flue 4 and is bent toward the reburning chamber 22 to blow air. At the leeward end, an air discharge port 31 for creating a negative pressure is provided in the reburning chamber 2.
It is open to two sides. The air line 2 for creating a negative pressure
7 is provided with a negative pressure generating air amount adjusting valve 32 as a means for controlling the amount of air discharged from the negative pressure generating air discharge port 31.

The other branch pipe line 29 is the main combustion air line 29 that constitutes the main combustion air supply device 3.
The bottom of the incinerator 2 communicates with the combustion chamber 10.
The main combustion air line 29 is provided with a main combustion air amount adjustment valve 33 as means for controlling the supply amount of combustion air into the combustion chamber 10.

Further, the remaining one branch line 30 is connected to the reburn air line 3 constituting the reburn air supply device 6.

When the blower 25 is operated and air is vigorously discharged from the negative pressure generating air discharge port 31 toward the reburning chamber 22, the flow velocity in the flue 4 increases and the pressure decreases. . Therefore, the combustion gas generated in the combustion chamber 10 is forcibly sucked into the re-combustion chamber 22 side.
The air supplied from the negative pressure creating air discharge port 31 acts as the reburning air in the reburning chamber 22 together with the air supplied through the reburning air pipe 30. Therefore, in the illustrated example, the combustion gas transfer device 7 also functions as an air supply device for reburning.

A gas for controlling the flow rate of the combustion gas from the incinerator 2 to the reburning furnace 5 is provided in the flue 4 upstream of the combustion gas flow from the negative pressure generating air discharge port 31. Inflow amount control means is provided. In the illustrated example, a damper 35 is employed as an example (see FIGS. 1 and 2).
reference). The operator operates the damper 3 so that the combustion gas flows into the reburning chamber 22 by an amount suitable for reburning.
5 can be adjusted from outside the flue 4.

The discharge amount of air from the negative pressure generating air discharge port 31 constituting the combustion gas transfer device 7 is
The amount of the combustion gas flowing into the re-combustion chamber 22 can also be adjusted by adjusting the air pressure adjusting valve 32 for creating a negative pressure. Therefore, these may be used in combination as needed.

Next, an incineration method performed by using the incinerator configured as described above will be described.

First, as shown in FIG.
Outside, a plurality of the large plate-like incineration objects 9 are stacked flat via a spacer 36. The spacer 36
For example, a square waste material made of an appropriate combustible material such as wood is used. Since the main combustion air circulation space S is formed between the individual incineration objects 9 by the spacers 36, the combustion efficiency is good and there is no unburned residue.

Next, the laminated incineration material 37 formed as described above is sent from the carry-in port 14 into the combustion chamber 10 while sliding on the roller device 21. Since the roller device 21 is provided, the stacked incineration object 37
Can be easily pushed by hand. At this time, if the incineration object mounting table 38 with a roller having the same height as the roller device 21 is provided in front of the carry-in port 14, the carry-in operation becomes easier.

When the loading of the stacked incineration material 37 is completed, the incineration material 9 is appropriately ignited in advance and the carry-in opening / closing door 15 is closed, and the main combustion air supply device 3 and the combustion gas transfer device are closed. 7. The combustion is performed by operating the reburning air supply device 6.

Here, depending on the constituent materials of the incinerated material 9, the combustion temperature in the combustion chamber 10 becomes too high to cause danger, or the amount of combustion gas generated in the combustion chamber 10 is reduced. In the case where the amount is too large, the main combustion air amount adjusting valve 33 is operated to operate the combustion chamber 10.
The amount of air supplied into the combustion chamber is reduced, and the combustion is intentionally incompletely performed in the combustion chamber 10. Then, the incomplete combustion gas generated in the combustion chamber 10 is completely burned in the re-combustion chamber 22 and released into the atmosphere. At this time, the damper 35 is operated to appropriately adjust the amount of incomplete combustion gas flowing into the reburning chamber 22 so as to match the reburning capacity of the reburning furnace 5.
