What factors are related to the charcoal yield of mechanical charcoal?

What factors are related to the charcoal yield of mechanical charcoal? There are two points in summary: 1. raw materials, 2. carbonization temperature. Here is a brief analysis based on these two points:

What factors are related to the charcoal yield of mechanical charcoal?

First, raw materials

The yield of charcoal shows a certain difference due to the different types of raw materials, that is, the quality of the raw materials determines the quality of the machine-made charcoal products. The content of wood fiber in the raw material has a positive effect on the yield of charcoal. High-density materials also generally produce dense and strong machined charcoal. For example, eucalyptus is a good raw material for making charcoal.

Second, carbonization temperature

Although the lower carbonization temperature can get a higher carbon yield, because of the low quality and corrosion of this mechanism, charcoal 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 degrees. The content of wood fiber in the raw material has a positive effect on the yield of charcoal. Machine-made charcoal production is more welcome for mature timber with strong structure. Dense materials also generally produce dense and strong machined charcoal. However, as the carbonization temperature increases, the fragility of charcoal will also increase. It is found in actual production that when the final carbonization temperature is between 550 degrees and 650 degrees, the brittleness of the mechanism charcoal and the solid carbon content Can achieve a more ideal equilibrium.
