The main functions of the continuous coconut shell carbonization furnace are as follows: firstly, the combustible materials in the gas-fired furnace (such as sawdust, rice husk, fruit shell, coconut shell, bamboo chips, bamboo, tree branches, wood edges, etc.) are introduced, and then the combustible gas generated after combustion is sprayed, cooled and purified in the pipeline, which serves as the heat source of the pre-carbonization. Ring, using the heat generated by the self to burn the self, to achieve energy-saving effect. The carbonization temperature of the new type of carbon powder carbonization furnace of continuous carbon powder machine is about 500 C, and the high temperature can reach 600 - 900 C. According to different raw materials, the output of single row continuous carbon powder mill is 120-150 kg/h. The output of double row continuous carbon powder mill is about 150-180 kg/h.

 

This machine adopts dry distillation carbonization mode, making full use of combustible gases such as carbon monoxide, methane and hydrogen produced during carbonization, separating wood tar and lignocellulose through flue gas purification system to obtain pure combustible gases, and then fully burning through self-matching air burner to heat high-temperature carbonization pipeline (temperature general control). It's about 600 degrees centigrade. There are four layers of pipes inside the carbonization furnace from top to bottom, two layers of preheating and drying pipes, the third layer of low temperature carbonization pipes, and the fourth layer of high temperature carbonization pipes. On the second floor, there is an independent exhaust pipe which mainly discharges water vapor. The pipe dries the material by using the waste heat in the furnace, and the water vapor is discharged from the exhaust pipe. The third and fourth layers are also equipped with independent flammable gas recovery pipelines, which carbonize materials at high temperature and decompose flammable gases such as carbon monoxide, methane and hydrogen. The pipelines are heated by recycling pipelines, flue gas purification system and burner combustion to achieve the effect of reciprocating cycle heating and carbonization. The primary ignition gas source of carbonization is supplied by biomass gasifier.
