[Stoves] ash layer beneath fire

[Dr.-Ing. Dieter Seifert]

DearVincent Okello,

For an improved air supply of the fire, a grate for the firewood is 
highly recommendable, as you certainly know. A grate with ash container 
can be produced simply from a rectangular steel sheet with upwards 
bended perforated sides, in which some rods are supported. Below this 
grid ash is deposited and produces an heat insulating effect.

You can introduce this grate with ash container also into the improved 
clay stove of Practical Action 
(http://practicalaction.org/the-improved-clay-stove).

One canmake a dough from ash with water and spread it on the pot 
outside, so that the soot can be easily rinsed off, as it is known in 
Africa.


With kind regards
Dieter

The layer would be about an inch thick after compression, and is about half an inch below the base of the stove.
