If you mean ash from an ash tree, then it's one of the best woods to burn on a fire or in a stove.
Gives out plenty of heat, is easy to split and will even burn when green.
If you mean does burning wood produce ash? Yes, it does.
yes
No, you cannot burn ash in a fireplace because ash is already a byproduct of burning wood. It is the residue left behind after the wood has been burned.
Burning of wood is an oxydation reaction; the products are carbon dioxide, water and ash.
Burning produce water vapors, carbon dioxide and ash.
soot, ash, charcoal
Ash is made from pulverized rock and glass created by volcanic eruptions.
Burning produces smoke (carbon) and gasses, such as Carbon Dioxide and Carbon Monoxide, along with water vapor. Ash is left after the wood is burned. We use our wood ash as fertilizer in our garden, for our grapevines, etc.
Wood ash (potash) is the main result of burning wood and potash can be used in the garden as a fertilizer. Also, if wood is slowly burnt (charred?) in a kiln, where oxygen is kept out, charcoal is produced.

Approximately 5-10 pounds of ash are produced from burning a cord of firewood, depending on the type of wood and how well it is burned.
Burning is an oxidation (reaction with oxygen): wood is an organic material and easily burn. The final products are water, carbon dioxide and ash.
The observable change for burning a log is the production of heat, light, and smoke.
