What is the Factors Of Charcoal Production now a day?
Charcoal has always been used as fuel material. However now, when gas, electricity and oil are commonly used, its production has declined. Unique characteristics of charcoal allow using it in various fields. Just recently it hasn’t been used commonly, but today it attacks more and more attention. Charcoal suits perfectly for domestic use – chargrills, fireplaces, barbeques, as it is smokeless and environmentally friendly. It can also be used in manufacturing industry: nonferrous machine industry (eg. to obtain aluminum, boron, etc.); in the production of pure silicium which is used to get semi-conductors; in chemical industry; metallurgy industry as deoxidant because there is a big amount of carbon in charcoal, in the production of glass, crystal, paint, electrode, plastic and in many other fields.
Charcoal for industrial use can be made of lumpy wood waste products of forest procurement, fuelwood and briquette of plant origin, i.e. the off-grade wood and other plant waste can be used as raw materials for charcoal production. In this case the cost of raw material will be minimal and therefore the prime cost of the product will be relatively law comparing to the market price. With high profitability and almost free of charge raw material, you may think that there is a snug in it somewhere. And there are indeed several potential problems there:
- In most cases charcoal is produced with the technology that has been used for several thousands of years. And this is not a metaphor.
- The consumer is willing to get charcoal with high qualitative indexes while the producer wants to get a high active output of commercial charcoal. This is impossible to achieve using old technologies.
- Domestic production is dangerous for the environment which means that it is impossible to use it near labor forces.
- Work conditions of this production are really arduous and dangerous to the service personnel.
There are many other disadvantages of domestic production but let us focus on the solution of the problem
Some more factors of charcoal from wikipedia
Prior to the industrial revolution charcoal was occasionally used as a cooking fuel. Modern “charcoal briquettes”, widely used for outdoor grilling and barbecues in backyards and on camping trips, imitate this use, but are not pure charcoal. They are usually compacted mixtures of sawdust with additives like coal or coke and various binders.
Historically, charcoal was used in great quantities for smelting iron in bloomeries and later blast furnaces and finery forges. This use was replaced by coke during the Industrial Revolution. For this purpose, charcoal in England was measured in dozens (or loads) consisting of 12 sacks or shems or seams, each of 8 bushels.
Purification and filtration
Charcoal may be activated to increase its effectiveness as a filter. Activated charcoal readilyadsorbs a wide range of organic compounds dissolved or suspended in gases and liquids. In certain industrial processes, such as the purification of sucrose from cane sugar, impurities cause an undesirable color, which can be removed with activated charcoal. It is also used to absorb odors and toxins in gases, such as air. Charcoal filters are also used in some types of gas masks. The medical use of activated charcoal is mainly the adsorption of poisons, especially in the case of suicide attempts in which the patient has ingested a large amount of a drug. Activated charcoal is available without a prescription, so it is used for a variety of health-related applications. For example, it is often used to reduce discomfort (and embarrassment) due to excessive gas (commonly known as a fart or flatulence) in the digestive tract.
Animal charcoal or bone black is the carbonaceous residue obtained by the dry distillation of bones. It contains only about 10% carbon, the remainder being calcium and magnesium phosphates (80%) and other inorganic material originally present in the bones. It is generally manufactured from the residues obtained in the glue and gelatin industries. Its decolorizing power was applied in 1812 by Derosne to the clarification of the syrups obtained in sugar refining; but its use in this direction has now greatly diminished, owing to the introduction of more active and easily managed reagents. It is still used to some extent in laboratory practice. The decolorizing power is not permanent, becoming lost after using for some time; it may be revived, however, by washing and reheating. Wood charcoal also to some extent removes coloring material from solutions, but animal charcoal is generally more effective.

Charcoal is used in art for drawing, making rough sketches in painting and is one of the possible media for making a parsemage. It must usually be preserved by the application of afixative. Artists generally utilize charcoal in three forms:
- Vine charcoal is created by burning sticks of wood (usually willow or linden/Tilia) into soft, medium, and hard consistencies.
- Powdered charcoal is often used to “tone” or cover large sections of a drawing surface. Drawing over the toned areas darkens it further, but the artist can also lighten (or completely erase) within the toned area to create lighter tones.
- Compressed charcoal charcoal powder mixed with gum binder compressed into round or square sticks. The amount of binder determines the hardness of the stick. Compressed charcoal is used in charcoal pencils.
One additional use of charcoal was rediscovered recently in horticulture. Although American gardeners have been using charcoal for a short while, research on Terra preta soils in the Amazon has found the widespread use of biochar by pre-Columbian natives to turn otherwise unproductive soil into very rich soil. The technique may find modern application, both to improve soils and as a means of carbon sequestration.
Charcoal was consumed in the past as dietary supplement for gastric problems in the form of charcoal biscuits. Now it can be consumed in tablet, capsule or powder form, for digestive effects. Research regarding its effectiveness is controversial.
Red colobus monkeys in Africa have been observed eating charcoal for the purposes of self-medication. Their leafy diets contain high levels of cyanide, which may lead to indigestion. So they learned to consume charcoal, which absorbs the cyanide and relieves indigestion. This knowledge about supplementing their diet is transmitted from mother to infant.

Special charcoals are used in smoking the hookah. Lit coals are placed on top of foil that is placed over the tobacco bowl. The coals “cook” the tobacco to a temperature that does not burn it but produces smoke.
