NOT COAL
Burnt Wood to cook and heat their houses.
When wood is burned to ash, that ash is mainly carbon. I'm pretty sure it's just carbon. Carbon is in everything and it doesn't burn very well so that's why it's left over from when you burn something.
The handle is either wood or plastic - both of which are good heat insulators - preventing the user from being burnt.
Decaying leaves mixed into dirt with a hand full of earthworms would be far better as fertilizer than burnt leaves. Burnt leaves would contain a high level of carbon but no cellulose. Mulch of leaves, grasses, soil, and earthworms would be better than burnt leaves because it'd be easier for the nutrients to leech into the soil.
The main content is the same. Of the wood is carbon and hydrogen, and that of fossil fuels is hydrogen and carbon. So when wood and fossil fuels are burnt the Carbon combines with oxygen to produce carbon dioxide and carbon monoxide, and the hydrogen combines with oxygen to produce water (H2O). C+O2--> CO2+CO
Burnt wood is essentially sterilized carbon. That won't hurt your dog, with one exception: If the "burnt wood" is burned lumber that was pressure treated, yes, it could poison your dog. But a burnt tree limb, or log of ordinary fire wood? No.
carbonised wood is burnt wood, and is usually black.
The main benefit from wood ash is Potash.

It is undergoing a physical change from wood to ash.
yes, it is a chemical reaction
coal is made when you burn coal

Particulate matter
The chemical energy in the wood that allows it to burn is transferred to heat, light, and sound energy.
