Airflow Carbonization Furnace Improves Charcoal Quality

Gongyi Tongli Machinery Factory is specialized in manufacturing and exporting of charcoal equipments and charcoal forming machine. The products produced by Tongli Machinery mainly include charcoal production equipments such as crusher, dryer, rod making machine, carbonization furnace and auxiliary equiptments like charcoal forming machine, belt conveyor, drum screen, etc.

The airflow carbonization furnace, which this furnace is ideal equipment for wood briquettes to have anoxic distillation carbonization. Due to its rational structure, the furnace only needs small quantity of heat consumption.  It adopted Superheated Stream cooling system, thus can speed up the cooling process, which also greatly increase carbonizing ratio (increased from about 88% to 99%) improve the quality of charcoal, and reduce the production cycling time ( from 24 hours to 6 hours). Its horizontal condenser can retrieve much wood tar. Blow is the working process of airflow carbonization furnace.

1. After extruded from the rod machine, the carbonization of rod materials can be 3 steps: low temperature damp exhaust--high temperature calcination--cooling. Before carbonization, the rod has water content about 8%, which would be a big problem of carbonization/charring since the moisture will seriously affect the charring quality. So the moisture removal time must be guaranteed, which needs 10-15 hours for kiln and 2-3.5 hours for mechanisms kiln. Long heating time can avoid rod cracking caused by moisture, and gurantee charring quality.
 
2. When the furnace temperature reaches 300°C, there are large amounts of combustible gases generated in the furnace. Generally speaking, 3m3 methane gas can be generated from 0.5kg rod materials, which helps to heat the furnace. Or use the gases as drying heat for dryers. The temparature for calcination is above 400°C and the furnace must be sealed with anaerobic closing fire. The cooling can be spontaneous cooling or water cooling.

 
3. After carbonization, first keep ventilation of the charcoal kiln(carbonization furnace) to prevent carbon dioxide poisoning. The charcoal should be placed outdoors more than 8 hours to complete cooling.

Gongyi Tongli Machinery Factory is a well-known airflow carbonization furnace manufacture. We design airflow carbonization furnace by our own innovative ideas, innovate airflow carbonization furnace, improve design process, greatly improved the production capacity, thus provide cost-effective airflow carbonization furnace and professional technical guide to our customers. The airflow carbonization furnacehave been exported to Russia, Uzbekistan, Myanmar, Vietnam, Laos, Kazakhstan and many African countries.
