What Are The Two Types Of Carbonization Furnace?

In recent years, there have been many customers enquiring about carbonisation furnace equipment. But many customers are not clear about the two types of carbonisation furnaces. Carbonation furnace can be divided into: dry carbonation furnace and continuous carbonation furnace. Which carbonisation furnace is better to use? What are the application areas of each? Today, ALLEN will introduce the difference between the two types of carbonisation furnaces in detail, so that customers can better choose the carbonisation furnace that suits their needs.


 

Dry Distillation Carbonation Furnace 

Dry Distillation Carbonation Furnace is a device for dry distillation of raw materials at high temperature to produce carbide. It usually consists of a closed reaction chamber and a heating system. During the dry distillation process, the raw materials are thermally decomposed in an oxygen-free or oxygen-poor atmosphere to produce solid carbides and other gaseous by-products.

Dry distillation carbonisation furnace can be divided into: preheating stage, drying stage, carbonisation stage, cooling stage, and finished product stage. Firstly, the raw material is heated to a certain temperature so that it has good thermal stability and fluidity. Drying is to evaporate the water in the raw material. Carbonisation is to heat the raw material to a high temperature in an oxygen-free and oxygen-poor environment to make it decompose fully into solid charcoal. The charcoal is then naturally cooled and waits for the temperature to be 50-60°C. Finally, the charcoal is discharged from the furnace.
  The main advantage of the dry carbonisation furnace features carbonisation in isolated air, without direct contact with fire. It belongs to the external heating type carbonisation furnace. It is widely used in: charcoal making, recycling precious metals, recycling waste electronic waste, environmental protection, and other fields.


 

Continuous Carbonisation Furnace 

Continuous Carbonisation Furnace is also called rotary carbonisation furnace, which is a commonly used carbonisation equipment. Its main features are: the furnace body can be constantly turned, so that the material in the furnace body receives uniform heat. Thus, the carbonisation process is fast and efficient. It usually consists of: furnace body, heating system, transmission device, gas purification system, and so on. In the continuous carbonisation furnace, the raw material is sent to the feeding port through the conveying device, from which it enters the rotary furnace body. With the continuous tumbling of the rotary furnace, it is fully and evenly heated. The heating system provides the heat source, so that the temperature inside the furnace body gradually rises. The material is thermally decomposed in an oxygen-free or oxygen-poor environment to produce solid carbon and gas by-products. The combustible gas generated in the carbonisation process, the combustible gas can be returned to the combustion chamber for heating through the gas circulation device. The carbonisation furnace has the features of high carbonisation efficiency, continuous automatic feeding and discharging, high quality of finished products, and convenient operation. It is widely used in biomass carbonisation, waste treatment, energy recovery, and other industrial fields.
