Charcoal is left over from burning wood. Why can it be barbecued?

No matter what season, barbecue has always been a very popular food. But many people who eat barbecue will ask, that is, the charcoal used for each barbecue should be the product of burning wood, so why can it be used for barbecue?

In fact, charcoal is not the product left after wood is completely burned. If the wood burns completely, the only thing left is plant ash, which can't continue to burn. Unburned wood is charcoal after cooling, so there used to be an ancient poem called selling charcoal Weng, which was used by people to burn wood into charcoal for sale. Wood is a complex organic matter, and charcoal is the product of his carbonization, which is the simple substance of carbon.

So charcoal is not the residue left by burning wood, it is different from those ashes. There are many kinds of charcoal, including white charcoal, black charcoal, activated charcoal and machine-made charcoal, each with its own advantages. Charcoal plays a vital role in combustion, and can also be used to make desiccant, which has very strong adsorption capacity and is non-toxic and harmless.

The reason why charcoal is used as barbecue material is mainly because there won't be many flames and choking smoke when charcoal burns. People who barbecue with charcoal often smell a strange smell of wood, which produces much less harmful substances than burning wood directly.

Charcoal can not only be used for barbecue, but also plays a very important role in all aspects of our lives. Activated carbon has strong adsorption capacity and is widely used. They are even used in the production of glucose and monosodium glutamate, as well as environmental protection in life. The discovery of carbon should be one of the most outstanding inventions of mankind.
