度に保つことができる。As described above, according to the present invention, a part of the wet raw material and the like is additionally charged into the high-temperature dry powder mass which is first charged into the inner cylindrical body and circulated therein. When mixed and dispersed, it can be dried quickly. That is,
Since the entire amount of the wet raw materials and the like was self-burning in the inner cylindrical body, the entire amount had to be dried and the temperature was higher than necessary. Therefore, the temperature becomes appropriate, and the processing capacity is increased by the amount of the additional raw material and the like. Further, in the present invention, the raw material in the form of a granular mass and the like that has been previously introduced and dried is rolled together with the additional wet raw material and the like that is directly fed into the combustion chamber, and is preferably mixed with the jet air from the supply gas. , The combustion efficiency is high and the combustion temperature can be kept at an appropriate low temperature.

的である。Since an additional wet raw material or the like is directly fed into the combustion cylinder chamber, for example, in the case of a raw material having a high nitrogen content such as sewage sludge, ammonia gas generated at the same time as the input is burned during combustion. It reacts with the generated nitric oxide to bring about a denitration effect. Further, the additional raw material and the like do not need to be the same substance as the raw material and the like previously charged into the inner cylindrical body. For example,
It is more effective to select an extraneous substance that easily adheres to the surroundings in a wet state or a substance that has a strong odor.
