For charcoal producers, 竹炭 and charcoal are two very common charcoal products and they are also very popular in the market. In our life, charcoal is generally used for barbecues. Charcoal is smokeless and resistant to burning. But bamboo charcoal is used for furniture decoration. Why is this? What is the difference between charcoal and bamboo charcoal? The 树立 charcoal machine manufacturer will answer your questions here.

木炭是如何制作的？

Charcoal is a dark brown or black porous solid fuel that remains after wood or other biomass raw materials are incompletely burned in a 炭化炉 和 earth kiln, or are pyrolyzed under conditions of isolation from air. Charcoal is an amorphous carbon that retains the original structure of the wood and tar residues in the pores.

Many charcoal producers will choose the compact charcoal production line for making charcoal on a large scale. In addition to being used as a living fuel, charcoal can also be used as a fuel for metal smelting, food and light industry, a reducing agent for electric furnace smelting, and a covering agent to protect metals from oxidation during metal refining. The use of charcoal is very wide.

竹炭是如何制作的？

在碳化设备中对竹材进行高温热解后得到竹炭。截面图案光亮，表面平滑无裂纹和皱褶，结构非常致密。敲击或跌落时，竹炭不易破碎，发出清脆的金属声。

竹炭的元素组成是竹炭性质的基础之一。它包括碳、氢、氧等元素以及灰分。灰分是竹炭在高温氧化条件下完全燃烧后残留的各种无机物的混合物。竹炭的元素组成含量由最大碳化温度决定。

木炭和竹炭之间的主要区别

  1. 组织结构不同

竹笋是中空并有节的。因为管束组织中没有层次，竹子不会变 thick，而是从节点向上生长。根据研究结果，竹子在生长最快时每天生长约120厘米。竹子的外部组织密集。

经过高温碳化与活化处理，竹炭的比表面积（BET）显著增加，约为木炭的三倍，其对挥发性有机溶剂气体（VOCs）的吸附能力强。

  1. 不同的功能。

木炭的炭含量可达到约87%–93%，因此可用作良好的燃料；竹炭的炭含量约为75%–86%，不适合作为燃料型碳材料。竹炭具有强吸附、过滤和屏蔽电磁波的功能。
