Dr. Karve,

It might be a better approach to embrace the dung as it is and make a
better stove!

Even if you process the dung, you will need to build a stove to burn it.
So why not skip the step of specialized dung processing and just focus on
the stove.

I would think there are some here experienced with high ash fuels.  There
must be solutions.

>From my own experience burning dung, it tends to smolder (smokes a lot).
I have assumed this was a function of surface area.

It seems to me the dung would burn better if its density was reduced.  But
that is counter to the desires for a dense shipable fuel.

So keep the dung dense until it reaches the stove.

I would then look to a system that reduces the density of the dung at fire
face so it can burn more vigorously. I am thinking of something like a
crank operated apple scratter (grinder) for making fruit juice.  hutps://
