の通り、優れた実用的効用を奏するものである。As a result, the cooling and cooling of the chute main body makes it difficult for dry fixation of the processing object to occur, thereby causing the growth of sediment generated by the adhered substance as a nucleus and the obstruction trouble inside the chute main body. Is effectively prevented. In addition, since the cleaning plate is driven by the cleaning plate driving device to automatically separate and drop off the deposits, there is no trouble in removing the deposits as in the past, and the deposits can be safely removed. A removal operation can be performed. Further, by supplying the cooling air of the chute main body as the combustion air into the furnace main body, it is possible to further enhance the thermal efficiency of the furnace main body equipment. As described above, the present invention has excellent practical utility.
