Carbonization Furnace

Azeus Machinery Provides Three Types of Carbonization Furnaces

☆ Self-ignition Carbonization Furnace Features

This type charcoal carbonizing stove adopts self-ignition principle to

decompose the briquettes into combustible gas, wood tar and charcoal. It

can be applied to carbonize wood, logs, biomass briquettes, fruit shell and

bamboo, etc. This charcoal carbonization machine is featured with easy

operation, high efficiency, no smoke, etc. Made of mobile steel plates,

this machine has large effective volume and long service time.

☆ Airflow Carbonization Stove Features

◇ Adopting advanced thermal current technology, this machine can

greatly improve carbonizing rate from 80% to 99%.

◇ Furnace effective volume is 3m³, 5m³, 6m³, 8m³, every model can be

customized.

◇ Carbonizing rate is more than 40-60%, yield of finished products is

more than 95%.

Note: About hoist type hot airflow carbon furnace, we just provide three

inner stoves for free, if you want furnace continuous working, need buy

additional inner stove. And mostly, because the shipping cost, our

customers just ask our engineer send the drawing of inner stove to them,

then they make it at their local.

Charcoal Carbonizing Process

Carbonization is a very important process for making charcoal briquettes.



The whole charcoal carbonizing process can be divided into the following

three stages

1. Briquettes Drying Stage

From the ignition until the temperature reach 160℃ , the biomass sticks

moisture evaporates steadily mainly depends on the heating resource and

independent burning value. There are no chemical changes in this stage.

2. Initial Carbonization Stage

This process mainly depends on the briquettes burning to produce heat

and makes the temperature rise to 160～280℃ . The biomass briquettes

start to have thermal deposition. For example, the hemicellulose

decomposes into CO2, CO and amount of acetic acid.

3. Comprehensive Carbonizing Stage(temperature 300～650℃)

In this stage, the biomass material undertakes chemical decomposition

radically. It produces much acetic acid, carbinol and wood tar as well as

combustible gas including methane and ethylene. These gases contributes

to making a high temperature and the biomass briquettes are distilled into

charcoal.

Notice

If you want to make pyrocarbon, the furnace temperature should reach

800℃～1000℃.

How to Choose Suitable Carbonization Stove?

The carbonizing technology and carbonization furnace play an important

role in the charcoal briquetting plant. Every one should consider how to

choose the most cost-effective machine for your plant according to the

budget, site condition and capacity. The following is comparison between

steel plate carbonization furnace and carbonization kiln.

☆ Steel Plate Carbonization

Advantages

1. Good sealed performance.

2. Long service life, usually more than 5 years.

3. High refractoriness. If the combustion chamber is made of insulating

brick, its refractoriness can be 400～500℃; for furnace chamber made of

high temperature castable, the refractoriness can be 1300℃ which can be

used for making pyrocarbon.

4. Quick ignition and even air inlet, the furnace temperature is adjustable.

5. Equipped with wood tar separator, reducing environmental pollution.

6. Short carbonizing period.

Disadvantages

More building cost than kiln and need extra transporting fees.

☆ Charcoal Carbonization Kiln

Advantages: low investment and simple construction

Disadvantages:

1. Long time ignition time, needing to burnsome briquettes.

2. Uneven air inlet. The briquettes cannot be carbonized completely.

3. Long processing time, 15-20 days.

4. Slow cooling, need cool water to help cool down the temperature.

5. No wood tar separator, making pollution.
