Hi Robert,
the quantity of ashes depends on the cooking time, briquette material and
how dry they are before inserted in the stove. Surprisingly enough, i used
12 briquettes to cook goulash, which took 4 hours and didn't have to clean
the stove even once (briquettes were of pine flakes and paper, it was just
white dust that remained after burn).
I did make one solution for the problem tho - i drilled a 1/2 inch hole
through the very bottom corner of the combustion chamber, from the side of
the stove (90 degrees to the elbow shape), which provided an option to
clean the stove with a stick that just fitted the hole (you just pushed the
stick through the hole couple of times and ashes were pushed out on the
other side. I'm sorry i can't provide any photos at the moment, but can do
so if desired!
I know Joshua Guinto (in Philippines) used to make a slightly lower
vertical part of the combustion chamber, so the ashes were falling in
there. I can make a drawing for you
All the best with your endeavors!
