After the flue gas generated by the materials burned in the carbonization machine is treated by the flue gas purification, it is returned to the carbonization machine for combustion, so that the thermal energy of the machine can be continuously operated to achieve smoke-free, environmental protection and continuous effects. Finally, the charcoal is transported by the cooler to cool down, so that the temperature of the charcoal is only 50-80 degrees when it comes out. During the process of the charcoal being transported after it comes out, because the charcoal fully contacts the air, if the material is dense and thick, there is no open flame on the surface. , there may be sparks in the inner core of the material, or it may spontaneously ignite.

It is necessary to install mist spray equipment to cool the charcoal for a second time, so as to completely eliminate the fire source.
