How to burn a good mechanism to barbecue charcoal

The so-called charcoal burning is to put the wood material into a high-temperature furnace to ignite. After a period of combustion and temperature rise, the fire is turned off to dry-reduced in an anaerobic state, and a black substance, charcoal, is produced through a pyrolysis process. If you want to burn charcoal, you must master the following essentials.

First, the joints around the charcoal kiln should be tight. No air leakage is allowed. If there is a gas leakage in the carbonization furnace, the amount of oxygen entering the furnace cannot be controlled. The fuel bar in the furnace is prone to auto-ignition, and the carbonization temperature rises too fast so that the charcoal that is fired is loose and easily broken. What's more, excessive oxygen will burn some of the fuel bars into a white powder (ash), which will reduce the output of charcoal and increase the cost of finished charcoal. To this end, before we use the mechanism charcoal carbonization furnace to charcoal, we should do a leak check according to the requirements of the manufacturer's technicians. This is a prerequisite.

When carbonized charcoal is actually used in a carbonization furnace, attention should be paid to the change in furnace temperature during the carbonization process.

First of all, we need to understand the rise of the furnace temperature, which is caused by the combustion of combustible gases that are self-igniting or decomposed by the salary bar in the furnace. Secondly, we must grasp the relationship between the temperature rise and the quality of carbon.

Generally speaking, under the condition that the carbonization furnace kiln does not leak, the temperature rises faster, the density of the produced carbon is small, the carbon is brittle, and the crack is much, but the charging time of the salary bar is greatly shortened, that is, it can be improved. The output of a single furnace. The carbon produced is suitable for industrial and agricultural carbon.

If the furnace temperature is controlled during the carbonization process, the temperature of the furnace is slowly increased, the internal structure of the salary bar is balanced, the decomposition is moderate, and the carbonization rate is slow, but the carbon structure is harder than the former, the carbon surface is smooth, the crack is small, and the ratio is large. There is a certain benefit to long-distance transportation of carbon, but the output of a single furnace is reduced. This kind of charcoal is more suitable for the use of charcoal for barbecue and hot pot. The quality of such charcoal is not only good but also economic value. However, its production capacity is not as large as the above, and producers must be aware of this.

In the carbonization process of the carbonization furnace, it is necessary to learn to observe the changes of the flue gas emitted from the chimney of the carbonization furnace.

The change in the color and amount of smoke emerging from the charring furnace reflects the carbonization of the fuel bar in the furnace. Experienced masters learn to look at the power of smoking. According to theory and practice, we have divided the following three stages for the change of smoke color and quantity.

1. Ignition and salary bar further drying stage, that is, the furnace temperature is below 150 °C, the amount of smoke from the furnace chimney is large and black. If a carbonization furnace with a tar cooling device is used, the color of the smoke is lighter than the former. If an environmentally friendly carbonization furnace is used, and a flue gas recovery device designed on the carbonization furnace, the flue gas generated at this time can be recycled.

2. The pre-decomposition stage, that is, the furnace temperature is between 150 °C and 270 °C, the amount of smoke is slightly smaller than the former, and the smoke color is yellowish.

3. In the decomposition stage, the furnace temperature is between 270 °C and 400 °C, the smoke is white, and the amount is gradually reduced and thinned.

If the amount of smoke is scarce, there is almost no color, and the color is blue and bright, which means the end of charring. At this point, you can “close the fire” and release the charcoal after cooling.

As long as we are skilled in mastering the above-mentioned charcoal carbonization technology, it is not difficult to develop good charcoal that meets the requirements of the producer.

The charcoalization of the mechanism charcoal is very important. If the charcoal is not good, it will be abandoned and the charcoal production will fail. But the production of mechanical charcoal, as well as a technology is also very important, that is, rod forming technology. Both are indispensable.
