For charcoal producers, bamboo charcoal and charcoal are two very common charcoal products and they are also very popular in the market. In our life, charcoal is generally used for barbecues. Charcoal is smokeless and resistant to burning. But bamboo charcoal is used for furniture decoration. Why is this? What is the difference between charcoal and bamboo charcoal? The Shuliy charcoal machine manufacturer will answer your questions here.

How is charcoal made?

Charcoal is a dark brown or black porous solid fuel that remains after wood or other biomass raw materials are incompletely burned in a carbonization furnace and earth kiln, or are pyrolyzed under conditions of isolation from air. Charcoal is an amorphous carbon that retains the original structure of the wood and tar residues in the pores.

Many charcoal producers will choose the compact charcoal production line for making charcoal on a large scale. In addition to being used as a living fuel, charcoal can also be used as a fuel for metal smelting, food and light industry, a reducing agent for electric furnace smelting, and a covering agent to protect metals from oxidation during metal refining. The use of charcoal is very wide.

How is bamboo charcoal made?

After high temperature pyrolysis of bamboo material in the carbonizing equipment, bamboo charcoal is obtained. The cross-cut mask is shiny, the surface is smooth without cracks and wrinkles, and the structure is very dense. When beaten or dropped, bamboo charcoal is less susceptible to breakage and breakage, and emits a crisp, crisp metallic sound.

The elemental composition of bamboo charcoal is one of the foundations of bamboo charcoal properties. It includes carbon, hydrogen, oxygen and other elements and ash. Ash is a mixture of various inorganic substances left after bamboo charcoal is completely burned under high temperature oxidation conditions. The elemental composition content of bamboo charcoal is determined by the maximum carbonization temperature.

Main difference between charcoal and bamboo charcoal

  1. Organization is different

The bamboo stems are hollow and knotted. Because there is no layer in the tube bundle tissue, the bamboo will not thicken, but will grow upward from the nodes. According to the results of the study, bamboo grows 120 cm a day when it grows fastest. The outside tissue of bamboo is dense.

After high temperature carbonization and activation treatment, the specific surface area (BET) value of bamboo charcoal has increased significantly, about three times that of charcoal, and its adsorption capacity for volatile organic solvent gases (VOCs) is strong.

  1. Different functions.

The carbon content of charcoal can reach about 87% -93%, so it can be used as a good fuel; the carbon content of bamboo charcoal is about 75% -86%, which is not suitable as a fuel-type carbon material. The bamboo charcoal has strong adsorption, filtering, and blocking electromagnetic waves.
