What is the key to the carbonization furnace production technology?

The complete set of charcoal machine equipment includes pulverizer, dryer, rod making machine, charring furnace. As the last process of making charcoal, carbonization is unavoidably important. The following is the key to the production process of the carbonization furnace by Gongyi Tongli Charcoal Machine Equipment Factory:

What influence does temperature control in the carbonization furnace have?

    Although a lower carbonization temperature can obtain a higher carbon yield, this charcoal has low quality and corrosiveness and contains acid tar substances, so it cannot be burned with a clean smokeless flame. The solid carbon content of high-quality commercial carbon should be higher than 80%, which requires us to control the final carbonization temperature above 500 ℃.

The wood fiber content of the raw material has a positive effect on the production of charcoal. Charcoal production welcomes mature materials with a strong structure. Dense materials can also produce dense and strong carbon. However, with the increase of carbonization temperature, the fragility of charcoal will also increase. In actual production, it was found that when the final carbonization temperature is between 550 ℃ and -650 ℃, the fragility and solid carbon content of charcoal Time can achieve a more ideal balance.

The key to burning the kiln is to control the temperature of the kiln. Through the adjustment of the air inlet, the purpose of controlling the temperature of the kiln can be achieved. The stable heating and cooling process is the guarantee for burning high-density charcoal. Taking the climatic conditions in Jilin in spring as an example, the entire process from ignition to charcoal production takes about 9 days, so that charcoal with a better density can be obtained.

For the southern carbon plant, the cycle is longer. The high-temperature carbon refining stage after the end of the spontaneous decomposition stage determines the solid carbon content of the charcoal. If you want to burn good charcoal, you must work hard to control the kiln temperature and high-temperature charcoal. In addition, the kiln body must be kept sealed at all times, and no air leakage is required, which requires us to be very careful when building the kiln, especially in the drying stage of the kiln body.
