What are the charcoal firing methods? The easiest way to burn charcoal

Charcoal is a dark brown or black porous solid fuel left over from incomplete combustion of wood or wood raw materials or pyrolysis in the absence of air.

Charcoal is an impure amorphous carbon that retains the original structure of the wood and the residual tar in the pores. Charcoal was used for the smelting of bronzes of the Shang Dynasty and iron tools of the Spring and Autumn Period and the Warring States Period in China, and its hygroscopicity was used to observe climate change.

There are two ways to make it:

1) Kiln firing method, build a kiln with clay, fill it with wood, burn it from the kiln door or fire gate, so that the wood is carbonized in the kiln, and the volatiles escape and the charcoal remains;

2) Dry distillation, that is, dry distillation of wood. According to the extinguishing method of the kiln, there are two kinds of black charcoal and white charcoal.

Brief introduction of charcoal kiln: there are many forms and structures of kilns, such as Zhejiang kiln, carp kiln, wooden scoop kiln, Hunan wood kiln and Sichuan wood kiln, fast iron kiln, machine kiln and so on. Usually the method of extinguishing the fire in the kiln is called the kiln extinguishing method, and the obtained charcoal is called"Black charcoal"。

When the wood is carbonized in the kiln, it is taken out of the kiln while it is hot, and then the method of extinguishing the fire with wet sand is called the extinguishing method outside the kiln. In the process of extinguishing the fire, the charcoal is calcined in contact with the air, and the outside of the charcoal is oxidized, and the resulting white ash adheres to the charcoal, which is called"White charcoal"。White charcoal is harder than black charcoal.

Soil method to make charcoal: first find a slope to dig a pit on the slope surface, it is recommended that the horizontal pit can be large or small, and then find a slate or other things with better oxygen insulation effect, the hole must be smaller than the slate.

Then put the wooden block into the hole and ignite it Burning It's not good to give advice here, the first time it is recommended to burn for a long time, but not too long, otherwise it will burn out Next time I look for a little feeling, I feel that it is almost the same, put the slate on the hole and seal it with soil to see if there is no smoke coming out, and it will be good to wait for him to extinguish it himself for about an hour.

The easiest way to burn charcoal is as follows:Preparation materials Tools: wood, tin cans, saws.

1. First of all, the prepared wood is sawed into small pieces, and then the wood is put into an iron can.

2. Next, drill a few holes in the middle of the lid of the tin can and cover the lid on the tin can.

3. Then place the sealed tin can on the fire and heat it.

4. After heating the meditation room for a while, take out the iron can and let it cool.

5. The production of charcoal is completed.

1. Farmers will dig a simple charcoal kiln on the hillside, and some will have several charcoal kilns fired at the same time, and the charcoal ash that has been burned before will be cleaned out first.

2. Put the wood used for charcoal burning into the charcoal kiln, and place the wood according to the size of the charcoal kiln.

3. Then light a fire and burn the wood.

4. Charcoal burning has been a tradition in China since ancient times, especially in rural areas, whenever in winter, it is the season with the highest demand for charcoal for people to heat.

5. If the wood cannot be burned completely, when it is burned to a certain extent, seal the kiln mouth and wait for a day or two before opening the kiln mouth.

6. Take out the charcoal, the charcoal burned by the original soil method.

7. If you don't grasp the heat well, some charcoal still has charcoal heads, and if they are not completely burned into charcoal, a lot of smoke will be produced when they are burned.

8. Pack the charcoal and take it home, and when it comes to winter, the brazier is generally used in the countryside to burn charcoal for heating.

Hello dear charcoal is mainly burned with the following wood: "1Hard charcoal:

It is mainly composed of hard broad-leaved woods such as Quercus and Quercus spp., and the secondary ones are Birch. Such as water green gang, birch, hemp oak, bitter oak, elm, maple and so on. 2.

Hardwood charcoal: charcoal made from a mixture of hard and soft hardwood wood. Such as poplar, linden, willow and so on.

3.Pine charcoal: Charcoal fired from pine wood or other conifer wood.

Such as masson pine, Korean pine, spruce, etc. If my answer is helpful to you, please give a thumbs up (comment in the bottom left corner), I look forward to your like, your efforts are very important to me, and your support is also the motivation for my progress.

Summary. Hello, glad to answer for you. 1. Hard and broad-leaved charcoal: mainly composed of hard broad-leaved woods such as Quercus and Quercus spp., and birch spp. Such as water green gang, birch, hemp oak, bitter oak, elm, maple and so on.

2. Broad-leaved charcoal: charcoal made by mixing hard and soft broad-leaved wood. Such as poplar, linden, willow and so on.

3. Pine charcoal: charcoal fired from pine wood or other coniferous wood. Such as masson pine, Korean pine, spruce, etc.

Hello NIH.

Hello, what do you need to help Xiaodu inquire for you.

Hello, what do you need to help Xiaodu inquire for you.

Stage 1: Drying process.

After ignition, the temperature in the furnace is heated from room temperature to about 100 degrees Celsius, because the temperature in the furnace is low before ignition, so this process uses warm high flame heating. After reaching about 100 degrees, the temperature in the furnace is heated to about 170 degrees to 200 degrees Celsius with a low heat.

The first stage takes about 2 hours and 30 minutes.

The second stage: pyrolysis process.

When the temperature in the furnace reaches about 170 degrees - 200 degrees, use a warm flame to heat the temperature in the furnace to about 340 degrees.

The second stage takes about 2 hours and 30 minutes.

The third stage: rapid pyrolysis process.

When the temperature in the furnace reaches about 340 degrees, the temperature in the furnace is heated from about 340 degrees to about 380 degrees - 400 degrees by using a warm fire.

The third stage takes about 2 hours.

The fourth stage: the end of carbonization.

When the temperature in the furnace reaches about 400 degrees, there is no obvious temperature change after that, use a small fire to heat, when the smoke output of the smoke outlet is significantly reduced and lightened, the fire is extinguished, the fire is sealed, and the carbonization is over.

The fourth stage takes about 40 minutes.

The fifth stage: cooling, carbon extraction process.

After the carbonization is completed, if no other cooling measures are taken, natural cooling is carried out, and there are two ways to seal the fire

Method 1: Seal the smoke outlet and cool it, the surface gloss of the carbon rod is good, and the cooling time of this method is about 16 hours.

Method 2: The smoke outlet is completely opened, cooled, this process is the same as the quality of the first carbon, there is no light measurement on the surface, and the cooling time of this method is about 16 hours.

In the above two ways, when the temperature in the furnace drops to about 40 degrees, the carbon production is more ideal.

Note: If the airflow carbonization furnace does not have a temperature measuring device or the temperature measuring device is damaged, the carbonization operation process shall be subject to 7-8 hours of warm firing. At the end of carbonization, when the amount of smoke from the smoke outlet is significantly reduced and weakened, the fire will be extinguished, the fire will be sealed, and the carbonization will be completed.

<>1. The principle of charcoal firing: charcoal is to volatilize the gas and liquid in the wood by heating. The rest of the material is the solid combustible part of the wood.

2. Kiln firing method: build a kiln with soil, fill it with wood, and burn it from the kiln door or fire door, so that the wood is quietly balanced and laughed in the kiln, and the volatiles escape and the remaining charcoal is opened.

3. Dry distillation method: Dry distillation and wood are burned together at the fire gate to make two kinds of charcoal: black charcoal and white charcoal.
