To provide a carbonizing system solving problems on a combustion nozzle that the nozzle is gradually blocked caused of substance stuck in carbonizing sewage sludge in the carbonizing system which discharges and burns dry distillation gas generated inside of a carbonizing tube from the combustion nozzle installed on the top of the carbonizing tube.
The invention relates to the screw type carbonizing system comprising a screw type carbonizing tube substantially horizontally installed in a carbonizing furnace with low oxygen atmosphere, and the material to be carbonized which is conveyed by a screw conveyer, is heated from outside and dry distilled, wherein a mechanism is installed to release the block of the nozzle by the gas belched to the combustion nozzle installed on the top of the screw type carbonizing tube. A guiding means which guides the gas belch toward the combustion nozzle from the end of screw conveyer axis is used. The mechanism which is capable of setting the position and time of gas belching to the combustion nozzle is preferably used.
