Hi Tone
I don’t know a thing or two about charcoal and its preparation, since I didn’t make or use it at all. Regarding the direct transfer of fuel carbon to CO, everything is very complicated there, but in simple words this can be explained by the fact that at high rates of air supply and the general passage of gas through the active layer, the carbon oxidation reactions do not proceed completely, there is simply not enough time for this and "unburned CO "is simply taken out of the reaction zone … It is interesting that the gas from such a gas generator has a higher content of combustible components, in contrast to the classical ones with the reduction of CO2
