Customers often ask about the difference between charcoal burning in earth kiln and carbonizing furnace. Let’ s learn about it today.

The main differences are as follow:

1.Investment cost. 

The construction cost of the earth kiln is relatively low, but it covers a large area and the labor intensity of the operators is also great. The equipment investment cost of carbonizing furnace is high, but the occupied area is small and the labor cost is low.

2. Time efficiency.

The carbonization time of the earth kiln is relatively long, and only once a week or so. But the carbonizing furnace can complete the carbonization operation within 8-10 hours.

3. The quality of charcoal.

Most people will say that the charcoal in earth kiln is good, because the carbonization speed of carbonizing furnace will affect the quality of charcoal. We have met a lot of carbonizing furnaces used by customers, and the charcoal burned out is no less than that of earth kiln. Therefore, the use of equipment has little influence on the quality of charcoal, mainly because the raw materials and firing process are more important.

4. Technical. 

Kiln burning charcoal requires extremely high technical requirements for carbonizers. Generally, people use kiln burning charcoal, and the temperature is a little bad. As a result, some charcoal will be burned in light cases, and all the charcoal will be destroyed in heavy cases. It’s relatively easy to use a carbonizing furnace to burn charcoal, because there is a thermometer on the carbonizing furnace. Novice can show the problem by means of the thermometer and burn charcoal according to the normal steps, which is much easier than the earth kiln.

5. Environmental protection.

Burning charcoal in earth kiln causes heavy smoke, and the wood vinegar produced will pollute the land. The carbonizing furnace has a large output, can recover and purify flue gas, realize return gas combustion, save energy and protect the environment, and meet the requirements of environmental protection.
