1. What are the types of charcoal?

coal is often called, but in fact coal and charcoal are two substances. coal is an ancient plant buried in the ground. The solid combustible minerals have gradually formed by complex changes. Carbon is a porous substance, carbon burning and coal.The principle of formation is similar, and the substance left by the wood after decomposing the organic matter under high temperature and hypoxia.There are four main types of charcoal:

1. charcoal: It is a dark brown or black polyitic solid fuel that is residual under the condition of isolation of the air under the condition of isolation of the air.

2. Coke: Under the condition of isolation of the air, it is heated to 950-1050 C. It is finally obtained by drying, heat solution, melting, bonding, curing, contraction, etc.

3. activated carbon: It is a series of processes such as charcoal, bamboo charcoal, various fruit shells, and high -quality coal through physical and chemical methods to make raw materials crushed, sieved, catalyst activation, rinsing, drying and screening and other processes processing and manufacturingAdsorption agent.

4. Carbon black: It is a kind of light, loose and extremely thin black powder with large surface area and is a product of natural gas, heavy oil, fuel oil, etc. under the condition of insufficient air.It is a kind of non -fixed carbon.

How to make charcoal

There are three main methods for making charcoal:

1. Kiln burning method

The kiln burning method is a method of burning charcoal with charcoal kiln. It uses soil to build kiln and fills wood. Burning from the kiln door or fire door, so that the wood can be carbonized in the kiln.

2. Stemming method

Wood dry distillation is to place the wood in a dry distillation kiln. The process of heating and decomposing charcoal under the condition of isolation of the air, putting the wood in the dry distillation kiln, heating and decomposition under the conditions of isolation of the air;Wooden gas can condense wood (caramel and caramel acid; the remaining solid is charcoal.

3. Carbon mechanism charcoal method

The charcoal machine is a machine that crushes raw materials such as bamboo and wooden sawdust, Peanut shells, corn sticks to a granular shape within 10mm. After drying the dryer, put it in a charcoal furnace for carbonized machines., Two -raw material waste use for charcoal.[The process of charcoal mechanism charcoal & gt; & gt;]

1. Is smokeless charcoal a mechanism charcoal?

Traditional charcoal has smoke when burning. With the improvement of environmental protection requirements, the charcoal with smoke has gradually been eliminated, so there is an invention of smoke -free charcoal.

Smoke -free charcoal is also produced by charcoal machines. During the production process, after the process of high temperature, purification, smoke removal, can be transformed into smoke -free, odorless and non -toxic cleaning charcoal as alternative products for traditional charcoal.use.

2. Is smoke -free charcoal harmful to the body?

When smoke -free and haugnds are burning, they do not really have smokelessness, but they are relatively small, and the taste is relatively light. Under normal use, it is not harmful to the human body.

However, it should be noted that smoke -free charcoal is essentially charcoal. It will still generate carbon monoxide in the case of incomplete combustion. If the indoor use and the carbon monoxide concentration is too highPay special attention when you are smoke.

3. Is it safe to warm with smokeless charcoal?

charcoal is a traditional heating material. With the development of society, there are more and more heating equipment, but there are still the habit of heating in some places, but there are smoke when traditional charcoal burns, which is used to warm and comfortable.Smoke -free charcoal, so is the smokeless charcoal heating?

No smoke -free charcoal has a long burning time, high thermal value, and no smoke. It is possible to warm it; however, it should be noted that the use of smoke -free charcoal is generally indoors. If the doors and windows are closed and not ventilated, carbon monoxide may be generated.If it causes harm to the human body, if the windows are opened, there will be heat loss, which will affect the heating effect. Therefore, it is generally not recommended to use smoke -free charcoal or other charcoal heating.

1. What are the differences between mechanism charcoal and charcoal

Two types of charcoal are divided into two types, one is the rustic charcoal, that is, the traditional charcoal, which is obtained by the burning of wood; the other is mechanical charcoal, which is squeezed and processed by wood fragmentation. So what is the difference between them?

1. What is charcoal

charcoal is not completely burned by wood or wooden raw materials, or heat solutions under the condition of isolation of air. The remaining dark brown or black porous solid fuels are the immeasurable non -pure carbon that keeps the original structure of the wood and the impure carbon in the hole.

2. What is mechanism charcoal

Mechanical carbon is a charcoal rod -shaped material made of wood fragmentation and squeezed processing. It is a charcoal made of machine.

3. The difference between mechanical charcoal and charcoal

(1) Different sources of raw materials: Mechanisms are mainly one or more or more by the mechanism of charcoal, carbon, Peanut shell, cotton shell, corn stalks, sorghum stalks, Beans stalks, sawdust, wood chips, granular shells, coconut shells, etc.Materials.Traditional charcoal is fired from wood, and it is commonly used.

(2) Different production principles: Mechanical charcoal is a carbon rod that contains wood containing wood, placed in the machine, which is an artificially synthetic fuel stick.charcoal is made of wood directly after carbonizing wood.

(3) Different combustion process: The mechanism charcoal is compressed by a variety of materials, so it is slow to burn, which means that its combustion time is long, but its burning value is low, and the heat generated is not very large.The charcoal composition is relatively single, the burning value is very large, and the heat generates a lot, but its burning speed is fast, and the continuous combustion time is not as long as the mechanism is charcoal.

2. Which of the mechanical charcoal and charcoal is better

Traditional charcoal is gradually banned because the traditional charcoal needs to cut off the high temperature of trees and pollutes. Most of the charcoal on the market is now the mechanism charcoal. Compared with the mechanism of charcoal and charcoal, the advantages are mainly:

1. More environmentally friendly

Do not cut down trees, use wood products waste to produce, become waste into treasure, and do not destroy the ecological environment.

2. High energy

Mechanical charcoal fixed charcoal content is about 80%, the heat value is 7500-8000kcal/kg, while the fixed carbon content of charcoal is low, and the thermal value is about 6500kcal/kg.

3. clean and hygienic

Mechanism charcoal -free and charcoal -free head, burning without sparks, during the burning period, the ash naturally falls without floating, 3%or 6%of the gray portion or 6%is less ash and flammable.

4. It is more convenient to use

Mechanism has a unified length and size, and the hollow or solid structure is more reasonable, which is conducive to burning and use.

5. The water content is lower

The moisture content of mechanism charcoal is about 5 %, which is lower than ordinary charcoal, and the combustion performance is better.

In summary, mechanism charcoal is better than ordinary charcoal in terms of performance and environmental protection.

1. What is charcoal powder

charcoal powder, also known as charcoal powder, is produced by charcoal, such as charcoal residue as raw materials, the products obtained by crushing, and charcoal powder that can directly produce biomass can be produced.Bian Skin and so on.

What is the use of charcoal powder

There are many uses of charcoal powder, and the main application areas are:

1. Industrial field

(1) Metallurgy: Add charcoal powder during the smelting raw iron, which can help smelting high -quality steel with fine -grained structures, tight castings, and no cracks.

(2) Chemical industry: It is mainly used as a carburizing agent to carburize the steel products.

2. agricultural field

(1) Improve the ground temperature: After the charcoal powder is applied to the soil, because the black carbon particles absorb the Solar heat energy, the soil temperature can increase the degree of Celsius and promote the germination of the seeds.

(2) Improve the soil: After the charcoal powder is applied to the soil, the roots can be generated on the surface of the carbon, which can form agricultural soil suitable for plant cultivation. It has improved the growth, color, and taste of grains, Beans and vegetables.

(3) Keep soil moisture: When the relative humidity is more than 50%, the carbon powder can quickly absorb about 20%of water, which can be used to maintain soil moisture.

(4) Slow -release agent as pesticides or Fertilizers: Use the adsorption ability of charcoal powder to keep the content of pesticides and organic Fertilizers in a balanced state.

(5) Change soil pH: increase the soil CO2 content, adsorb the harmful metals in the soil, and increase the vitality of soil microorganisms.

3. The field of life

There are also many charcoal powder in the field of life. Common ones are activated carbon, charcoal carving, and water -tobacco charcoal. They are also widely used in the fields of fireworks and firecrackers and mosquito coils industry.

3. How much is charcoal powder per ton of one ton

charcoal powder is made of charcoal. The price is relatively cheaper. Generally, charcoal powder on the market is generally about 1800-2000 yuan per ton. There are also some expensive charcoal powder for more than 3,000 yuan per ton.(The above price source network is for reference only)

1. Mechanical charcoal production process process

Mechanical charcoal is a charcoal produced with charcoal machines. The process of producing charcoal in charcoal production machine equipment is divided into four steps:

1. Broken

Prepare the raw materials of charcoal and put them in the crusher. The crushing quality and quality are an important step in the quality of the manufacture of charcoal. After repeated testing and experiments by the engineer, the raw material of the charcoal machine is crushed to 3 mm of 3 mm.The following can be better formed. If it cannot be fully crushed, it is recommended to use 2 crushed or 3 crushing.

2. Dry

After the crushing machine is crushed, the raw material is transferred to the dryer, and the dryer dry these particles, so that the material can reach a certain degree of drying.Generally, only the prerequisite for producing a good quality charcoal between 6%and 12%of the water content is between 6%and 12%.

3. Make stick

After crushing and drying, it has entered the key steps of charcoal manufacturing. This step is generally used to complete the rod machine. The raw materials with a certain degree of drying are suppressed into a rod through high temperature.

4. Carbonization

The products obtained by making rods are generally called salary rods. It is not the charcoal of the finished product. The charcoal of the finished mechanism must be treated by charcoalization. It is only the mechanism charcoal after cooling.

2. How to produce good mechanism charcoal

A good mechanism is charcoal, high carbon content, beautiful appearance and firming, high hardness, and high burning temperature, but it is not so easy to produce high -quality mechanisms.In terms of aspect:

1. The raw materials are critical

The production of charcoal is the most important. Although the raw materials of mechanism charcoal are widely sources, those who can truly produce high -quality mechanism charcoal are still wooden raw materials.

2. The charcoal machine is good

The charcoal machine is one of the key elements of high -quality mechanism charcoal. It includes crushing machines, dryers, rod machines and charcoal furnaces. The quality of these machines and equipment directly affects the quality of the finished mechanism charcoal.

3. Carbon technology learning

With good machines, good raw materials, there must be good carbonization technology. Only by using the appropriate carbonization technology to burn good charcoal because of the aptitude. It should be noted that the machines and technologies used by different charcoal raw materials are notThe same.
