Charcoal Making Machine FAQs

About Raw Materials

What raw materials are suitable for charcoal making machine?

1.Various kinds of biomass and agricultural wastes, such as rice husk, coconut shells, palm kernel shell, bamboo, wood chips, sawdust, olive husk, coffee husk, fruit husk, hazelnut husk, oak, jute stalks, sugarcane bagasse, peanut husk, sunflower stalks, plant straw, peach pit, etc.;

2. Sludge: such as municipal sludge, river sludge, industrial sludge;

3. Domestic waste: municipal domestic waste.

Can I use the same equipment to deal with all types of raw materials?

No. Different raw materials require different temperatures for carbonization, so the furnace materials vary. It is recommended to use different furnace materials for dealing with different types of materials to adapt to different temperatures.

What are the feeding requirements for continuous carbonization?

The particle size of raw materials should be less than 20mm, preferably 8-12mm, and the humidity should be less than 15%.

About Final Products

How is the charcoal yield of your carbonization machine?

The charcoal yield is related to the temperature and frequency of biomass carbonization. We use frequency conversion control, which can be adjusted at any time according to your requirements for charcoal. Taking wood chips, rice husks and crushed coconut husks as examples, 260kg-310kg of finished charcoal can be obtained from each ton of materials with humidity below 10%, basically keeping a 3:1 charcoal yield.

What is the usage of biochar?

The biochar can be used to produce barbecue carbon, soil remediation, activated carbon, hookah carbon, metallurgy, etc

How to calculate the charcoal yield of 1 ton of biomass materials?

If the humidity is 10%, it is basically 3:1. If the humidity exceeds 30%, subtract the weight of water from the raw materials and divide it by three to get the charcoal yield.

How to improve the charcoal yield?

Reduce the reaction temperature of materials and shorten the carbonization reaction time of raw materials.

How to improve the fixed carbon content of finished charcoal?

Increase the carbonization time or increase the carbonization temperature of the furnace. Both of the two methods can increase the fixed carbon content of the finished charcaol, but will reduce the charcoal yield. Increasing the speed of the carbonization furnace can increase the charcoal yield, but will reduce the fixed carbon content of the finished charcoal. So we must first confirm with the customers whether they have requirements for the quality of finished charcoal (fixed carbon content).

With the increase of carbonization temperature and time, how much will the proportion of fixed carbon content increase?

For the same material, if the carbonization temperature and time are increased, the fixed carbon content will increase about 5% – 10%.

How about the quality of charcoal produced by your carbonization process?

The quality of charcoal has a certain relationship with the material itself and the reaction temperature and time. If you have requirements for charcoal parameters, please provide relevant parameters. We will adjust the equipment according to your needs to meet your needs.

When the raw material contains 10% water, what is the remaining 70% besides the 30% charcoal yield?

For the remaining 70%: about 56% of combustible gas, 8% of wood vinegar, 2% of tar, 2% of water and 2% of dust.

How much tar and wood vinegar can be obtained from carbonization of biomass?

Taking feeding 1t/h sawdust with 10% moisture as an example, we can obtain about 40-60kg of wood vinegar (PH 3-4) and 20-40kg of tar.

How do you deal with tar and wood vinegar?

How do you deal with tar and wood vinegar?

How do you solve the problem of tar and wood vinegar clogging the pipe?

1. Adjust equipment structure to reduce dust content in combustible gas;

2. Increase heat tracing and insulation to reduce tar precipitation;

3. Adjust the installation angle.

How to collect tar wood vinegar?

It needs to add condensate system to collect tar wood vinegar.

How to solve the problem of tar precipitation in combustible gas?

The heat of tar is worth using when very little tar is burned with combustible gas in the furnace.

Can the combustible gas generated in the carbonization process be collected? What can it be used for?

Customers can collect the combustible gas in special containers on site as required. The combustible gas can be used for heating other equipment due to its certain calorific value.

How much combustible gas will be produced by carbonizing one ton of raw materials?

In the biomass carbonization process, each ton of raw material can produce about 700kg of combustible gas.

Taking biomass as an example, what is the calorific value of carbonized combustible gas?

Calorific value is about 2800 kcal/kg.

Can combustible gas be collected for power generation in boiler plants?

Yes, the surplus combustible can be supplied to the boiler. But it should be noted that we can only be responsible for the supply of combustible gas, not power generation related matters.

What is the size of the finished charcoal from the ball pressing machine?

40mm-60mm. Other sizes can be customized with custom molds.

Does your equipment produce dioxins?

No. Dioxin is generated from the burning of chlorine containing materials. Our materials generally do not contain chlorine. In addition, the carbonization process is conducted in a low oxygen environment and does not directly burn, so dioxin will not be generated.

What is the effect of carbonization temperature and time on fixed carbon content? What is the relationship between fixed carbon, volatile matter and ash?

The higher the temperature and the longer the residence time, the greater the fixed carbon content; With the increase of fixed carbon, volatile matter decreases, and ash content generally increases; It mainly depends on the content of ash and volatile in the raw materials. If the ash content in the raw materials is high and the volatile content is low, the ash content in the carbon may also be reduced.

About Process & Operation

Can your equipment meet the environmental protection standard?

The proportion of chemical adhesives added is about 3% – 5%.

What iutilization rate of carbonization equipment?

5500-5800 hours per year.

Does your carbonization equipment consume high energy?

We never talk about the energy consumption of equipment. What we do is to make the best use of energy and give full play to its value. Energy consumption is directly related to the level of production costs. We are as concerned as you. During the carbonization of materials, some of the purified combustible gas can be used to heat the carbonization equipment, and the surplus can be used for other heating equipment and other purposes. The high-temperature waste gas generated in the carbonization furnace area is used to provide heat source for the front dryer after purification, and the whole process is energy-saving.

Is your carbonization equipment safe?

Very safe. Safety in production is no trivial matter. We have always attached great importance to this issue. The whole carbonization process is in a low oxygen and negative pressure environment. The materials inside the carbonization equipment do not contact oxygen and do not have combustion conditions. In addition, explosion-proof devices are designed at the end of the equipment to ensure safe operation of the equipment.

What are the precautions for using the equipment?

Due to different materials and supporting processes, our installation personnel will train operators on how to operate and daily precautions according to your materials and actual operation after installation and commissioning. The operation manual (including maintenance items and how to maintain) will also be delivered to you along with the equipment.

What if the carbonization temperature exceeds a certain level?

Our control system screen will display the operation of all parts of the whole set of equipment. If the temperature is abnormal and beyond the normal operating range,

1. PLC will automatically alarm and remind;

2. Relevant linkage work will be started, such as reducing the conveyor frequency, reducing the feeding amount, increasing the fan frequency, etc. to stabilize the working temperature.

How much natural gas or diesel oil does BST-30 and BST-50 consume?

The calorific value of natural gas is 9000 kcal/m3, and that of diesel oil is about 8160 kcal/l.

For the initial heating of BST-50, if natural gas is used, the natural gas consumed per hour is about 160-200 cubic meters. If converted into diesel, it is about 176L – 220L. After normal production, about 0-60 cubic meters of natural gas will be consumed per hour.

For the initial heating of BST-30, if natural gas is used, the natural gas consumed per hour is about 120-140 cubic meters. If converted to diesel, it is about 132-155 liters.

How to clean the molding machine?

After each production, the residual charcoal powder of the equipment shall be cleaned in time. The long-term residue of the added adhesive will cause uneven discharge.

About Configuration

What is the material of the main carbonization furnace? What is the acceptable temperature?

Q245R+310S. The outlet temperature of hot smoke detection point is 450-600℃, which can withstand the temperature within 650℃.

How much water does the dryer subtract?

One drying can remove up to 25% – 30% moisture.

How much occupied area do you need for charcoal making equipment?

The plant area of different types of equipment varies from 400 to 800 square meters. You need to consider the storage area of raw materials and the storage area of finished charcoal. You can contact us for detailed data.

What equipment is needed for making charcoal by Beston machine?

The molding production line needs to be configured according to your requirements for end products.

For the configuration of carbonization and drying, is the dryer temperature adjustable?

It can only be used for cooling adjustment, and the hot air duct of the dryer needs to be modified to meet this requirement. (In this process, the temperature of the dryer is derived from the furnace waste heat generated by the carbonizer, and the equipment gives priority to ensure the operation of the carbonization equipment)

What does the condenser do?

Collect tar and wood vinegar from combustible gas, with wood vinegar on top and tar on the bottom (mixed liquid, natural standing and separation).

What will happen if there is a power failure in the system?

There will be no danger. The main carbonization furnace will stop rotating, the combustion chamber will stop burning, and the slagging system will not continue slagging. Combustible gas will be discharged from the pipeline to the outside.

What will happen if the moisture is too high to be dried?

When the moisture content in the combustible gas is too high, it is not easy to ignite, which directly leads to increased operating costs;

The output of equipment declines in a stepwise manner, which cannot form a virtuous circle.

What will happen if the material is broken to too small size (less than 5mm)?

Increase the working pressure of the dedusting part, and increase the dust content in the combustible gas at the same time;

Increase the frequency of maintenance.

What are the advantages of replacing the main furnace with stainless steel compared with ordinary boiler steel?

1. The reaction temperature in the furnace is higher, and the high temperature reaction can increase the content of fixed carbon (get high-quality biochar);

2. The service life of the main furnace will be extended, but the service life of the whole production line will not change much, because the furnace, transmission part and pipeline are still original (the weakest part of the whole production line is the pipeline).

About Service

How long is the service life of carbonization equipment?

The service life of the carbonization system is 5-8 years. After the service life is over, only the combustible gas system and pipelines need to be replaced, and the main carbonization reactor can continue to be used after maintenance.
