Charcoal can be divided into two types, one is the primary charcoal directly fired from broken miscellaneous wood or logs, and the other is the machine-made charcoal made from charcoal-making machines.

The old-fashioned process is charcoal burning, that is, cutting the trees into sections, igniting them in a charcoal kiln, and burning them to a certain extent, so that the air in the charcoal kiln is sealed, and the residual heat continues to heat the wood for dry distillation, so that water and wood tar are extracted, and the wood is carbonized into charcoal. This is similar to burning firewood and pressing charcoal in the past.

At present, there is a method for processing machine-made charcoal, which is to use sawdust and other waste materials, press and shape them, and indirectly heat them in a furnace for dry distillation to carbonize these raw materials into charcoal.

Barbecue charcoal introduction:

First, we will dig a charcoal kiln. Fill the kiln with semi-dry firewood. Then seal the kiln, and then burn the small kiln in the kiln for a day or two from the fire pit dug when digging the kiln. The principle is to carbonize firewood at high temperature in an anoxic environment.

The principle is the same, all of them are anaerobic carbonization in kilns, but in recent years, with the introduction of the ban, there are few clay kilns left, so charcoal burners set their sights on carbonizer. Airflow carbonization furnace and dry distillation carbonization furnace are two different equipments. Dry distillation carbonization furnace can recover flue gas more effectively, which meets the requirements of environmental protection.
