。Unburned soot and dust generated during combustion of waste rubber is captured and eliminated by a porous ceramic plate 17 disposed at the upper part of the furnace 4. Furthermore, the bad odor is caused by a radiation converter 1 made of porous ceramics installed in the flue connected to the upper end of the furnace 4.
It is completely removed at high temperature in a heating chamber 19 surrounded by 8. The heating chamber 19 includes a fuel and air preheater 21 in a line 20.
The air that has been preheated by the air and comes through the line 22 is supplied, and serves as a heat source for maintaining a high temperature field of 800 to 1000°C. A fuel line 23 connects this heating chamber line 20 and the furnace 4.
It is branched into a line 24 for ignition inside. The porous ceramic plate 17 and the radiation converter 18 are porous bodies (made of ceramics) having 5 to 50 holes per inch,
It has a high heat transfer coefficient from gas and has excellent heat resistance.
予熱空気は、上記加熱室用のライン２２、前記点火用の

イン１１を経て系外へ排出される。In this embodiment, a moving grate (stoker) 9 is used, so that the non-combustible materials on the grate, the desulfurizing agent CaCO2, and the Cab, Canon, etc. generated from this desulfurizing agent fall from the end of the stoker 9. Among these, foreign objects such as wires and metal pieces are sorted out by, for example, magnetically in the foreign object remover IO, and are discharged out of the system through a line 11.

Then, it is sent out from line 15 for use as a low-temperature desulfurization agent in desulfurization, which will be described later. Deposits such as aSO4 at the bottom of the tank 14 are discharged to the outside of the system through the line 16.

射され、最終低温排ガスが脱硫される。The combustion waste gas leaving the heating chamber 19 is guided to the exhaust gas/water heat exchanger 28 after heating the air in the air preheater 21 . Here, steam is created from the heat of the exhaust gas. This steam is sent via line 29 to, for example, a water dispenser (not shown) for use, and its condensate is returned via line 30 to exhaust gas/water heat exchanger 28 again. The low temperature desulfurization agent sent out from the tank 14 through the line 15 is transferred to the line 31.
The final low-temperature exhaust gas is desulfurized by being injected into the flue 32 downstream of the exhaust gas/water heat exchanger 28.

復水はライン３０へ循環する。Fig. 2 shows an example of using the thermal energy of exhaust gas in a water dispenser. In Fig. 2, 4 is the furnace mentioned above, and the water introduced from the line 30 to the heat exchanger 28 recovers the heat of the exhaust gas. The thermal energy of this steam, which exits from the line 29 as steam, is recovered to latent heat in the tank 51, and the condensed water is circulated to the line 30.

3 to the next tank 54, the heat it possesses is used to evaporate the water in the seawater in the tank 54, and it condenses itself to become condensate, which exits through the line 55.

The first final stage is condensed with seawater introduced from line 56, and the resulting fresh water is taken out from line 57.
