The charcoal furnace equipment is an important equipment for the production of charcoal by the charcoal machine, and the operation technology of the equipment is also the key to the production of mechanism charcoal. Therefore, the correct operation of the charcoal furnace equipment to produce the mechanism charcoal can ensure the quality of charcoal and avoid equipment failure. Bring more economic benefits.

There are various methods of carbonization of the carbonization furnace equipment, which can be basically divided into two categories: internal combustion method and dry distillation method. Carbonization is divided into three stages: low temperature exhaust, high temperature calcination, and cooling. The carbonization temperature should be 550 ℃ -600 ℃. When the salary stick enters the carbonization furnace equipment, it has about 8% moisture, which is the enemy of carbonization. Because salary sticks are afraid of getting wet. Tide exhaust time is generally 10-15 hours for earth kiln and 2-3.5 hours for kiln. Long heating time can prevent the moisture stick from cracking and ensure the quality of carbonization. When the furnace temperature rises to 300 ° C, a large amount of combustible gas can be generated in the furnace. These gases can be used to heat the furnace. Drain the heat source available for drying. Above 400 ℃ is the heat preservation and calcination stage, which needs to be sealed without oxygen and closed fire. Can take self-ignition cooling or water cooling. After the charcoal exits the kiln, ventilate the charcoal first to prevent carbon dioxide poisoning. The charcoal leaving the kiln should be left outdoors for more than 8 hours to prevent re-burning of dead ash and fire.

The quality of charcoal is closely related to the raw rod. Generally, the density of the raw rod should be greater than 1. The simple detection method is: take a section of the raw material rod into the water, the specific gravity of sinking in the water is greater than 1, the specific gravity of floating is less than 1, the density of the specific gravity is higher, and the quality of the produced charcoal is good.

The working principle of the carbonization furnace equipment: First, the combustible materials in the gasification furnace (such as sawdust, wood scraps, etc.) are burned, and the flue gas generated after combustion is sprayed, cooled, and purified in the pipeline. Gas, as a heat source for the early carbonization, is used for the raw materials (such as rice husk, sawdust, straw powder, fruit husk, palm) in the 1 #, 2 #, 3 #, and 4 # carbonization tubes in a single-row or double-row combined shell ash carbonization furnace Shell, hemp, etc.) for heating and carbonization. All the flue gas generated in the carbonization process is recovered, and the generated combustible gas is subjected to secondary combustion through processes such as spraying, cooling, and purification. Circulate in this way, use the combustible gas produced by the body to burn the body to achieve the effect of energy saving. No smoke emissions during the entire production process, meeting national environmental protection requirements. The birth of carbonization furnace equipment not only protects the environment, but also can turn waste into treasure and bring wealth to people. It can be said to be a good device for many purposes. The use of the fruit shell carbonization furnace has increased the output of the equipment, shortened the carbonization time, produced no smoke pollution in the production environment, and saved energy into waste.

The main factors affecting the carbonization and carbonization rate: the type, density, and carbonization temperature of the raw materials. The denser the mature charcoal, the better. The carbonization temperature is low, and the carbon output rate will be high, but the soot is large and corrosive; the carbonization temperature is high, and the charcoal is brittle and easy to bend and crack; The balance between them is ideal. The solid carbon content of high-quality carbon is higher than 80%.

The above is the method and principle of carbonization production of carbonization furnace equipment. Users must properly operate the carbonization furnace equipment to produce mechanism charcoal in order to make it better. Economic benefits.
