Is hot pot charcoal the same as barbecue charcoal?

Hot pot carbon is different from barbecue carbon. Hot pot should choose machine-made charcoal, which has long burning time and strong firepower. Ordinary charcoal can be used for barbecue, with short burning time and weak firepower.

Charcoal, the name of a fuel. It is a dark brown or black porous solid fuel left by incomplete combustion of wood or wood raw materials or pyrolysis under the condition of air isolation.

Charcoal is an impure amorphous carbon, which keeps the original structure of wood and leaves tar in its pores. Charcoal was used in bronze wares of Shang Dynasty and ironware smelting in Spring and Autumn Period and Warring States Period in China, and its hygroscopicity was used to observe climate change.

physicochemical property

Charcoal is mainly composed of carbon with low ash content, and its calorific value is about 27.2 1~33.49 MJ/kg. In addition, there are hydrogen, oxygen, nitrogen and a small amount of other elements, and their contents have little to do with tree species, mainly depending on the final temperature of carbonization.

Charcoal is a hydrophobic substance, with ash content less than 6%, porosity accounting for more than 7% of its volume, specific gravity generally being 1.3 ~ 1.4, calorific value depending on carbonization conditions, generally about 8,000 kcal/kg, and its reduction capacity is greater than that of coke.

Charcoal has a large number of micropores and transition holes, which not only makes it have a high specific surface area, but also has good adsorption performance after removing tar substances from the holes. Complete combustion with oxygen produces carbon dioxide, and incomplete combustion produces toxic gas carbon monoxide. Relatively loose.
