Question: Why does coal burn so long?

“Unlike timber, coal when it gets hot has massive thermal mass which is very hard to extinguish. … Coal, and particularly brown coal, is very reactive to oxygen, and will generate CO2 and that creates heat. As the coal gets hotter it will eventually get to flame temperature and that coal will burn.”

  • Anthracite.
  • Bituminous.
  • Lignite.
  • Smokeless.

What burns hotter charcoal or wood?

Charcoal has an energy value of around 29 MJ/kg, in other words charcoal burns hotter than wood, but when not insulated or not receiving sufficient air supply (including secondary air), the absence of flames or fast flowing CO2 gases will result in less efficient cooking due to a lower heat transfer efficiency (HTE).

Can you burn carbon?

Yes, diamond can be burned. The most common form of burning in everyday life is carbon combustion. In carbon combustion, carbon atoms break their bonds with each other and with other atoms (which requires energy) to form bonds with oxygen atoms (which releases even more energy than first required).

Does wood turn into coal?

When wood is burned, oxygen and other elements in the air (mainly carbon, hydrogen and oxygen) react to form carbon dioxide that is released into the atmosphere, while the minerals turn into ashes. … Thus the carbon is left to turn into charcoal.

What is hotter flames or coals?

Are Coals Hotter Than Flames? No, given all else being equal, coal has the same potential heat as the wood beginnings, but due to the lack of oxygen and surface area, they produce less heat.
