[Stoves] Charcoal stove design

[Frank Shields]

Dear Crispin,

 

So the CO2 > CO is endothermic. But still needs carbon. As I see it the only
difference is the temperature changing as the gases move around the pot.
Wondering if the reading could be affected by temperature? Perhaps amount of
gas entering the instrument or something? Interesting. Could hydrogen react
with one of the oxygen in CO2 making water leaving CO?

My conclusion is the CO splits endothermically. It does not happen in stoves
with high EA.

Dear Crispin,

I found that directly above the middle of a good stove (under the pot) there
is zero CO - I was amazed. But nearer the edges there is more.

occur be in a bed of char. This is very strange.
