Is there a chance that ashes would increase the heat produce by stoves at home?

Question

I am conducting a research. I wanted to know if there is any connection between ashes and amount of heat. What I want to find out is what could be the effect of ashes in heat. Is there a chance that in making ashes as a component of a material would this material be of any help in enhancing the heat produce?

Answer 1

considering ur trying coal or other burning material as fuel.

if the ash content is more means then the heat conductivity will be less from core of the fire.

ash is formed due to loosely packed material and has very less heat in it.

ash has less sp.heat capacity.

Answer 2

Of course not! Ash is the remants of a consumed product. Ie coal, wood or paper. There is nothing left to consume, that is why it's ash. It can't hold heat, if it could people would have found a way to insulate their stoves in the old days to conserve heat.

Answer 3

i have 2 wood stoves in my house that i've been using for almost 25 years and i have found that the ash acts more like insulation and air filter, it aids in slowing down the burning of the coals( not the wood). after a fire has burned down, the ash covers the coals so when i stoke the ashes to uncover the coals, fresh air hits them and they start burning hotter in order to get another fire going. a blanket of ash also aids in keeping the stove hot longer
