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.

 Working Principle of charcoal carbonization furnace:

It uses movable steel structure,and furnace top of the exhaust pipe is connected with a tar separator and

a draft fan coupling, showing features of unique structure, large effective volume, advanced carbonization

technology , short cycle, high yield, good environmental protection performance, and long service life etc.

Advantage of charcoal carbonization furnace:

1. Easy operate and maintain, higher safety, energy saving 

2. High carbonization rate ,no smoking, little pollution, high efficiency 

3. Newly developed carbonization stove, which can dry the materials with the superfluous energy produced

 in the process of carbonization. 6-8 hours per stove and can work continuously 

4. The tube of fume extraction will recycle the gas flow which come from the inner stove during the carbonizing

process for continue warming the stove, and it will save 70% energy consumption and recycle 95% smoking

Suitable raw materials of carbonization furnace

wood pallet crusher can make  all kinds of branches,rice hull, bamboo powder, peanut husks, furfural dregs,

wine stillage, bagasse,corn cobs etc.
