[Stoves] CO/CO2 Ratio in the Charcoal Stoves Tested at Aprovecho

[Tom Miles]

Dean,

The CO/CO2 graph provides a very different picture of the cook. 

Closing the door on the Jiko to simmer doesn't seem to have changed the
CO/CO2 ratio. Opening it to maintain the simmer doubled the CO/CO2. 

The Jiko firing looks pretty stable. The rocket is clearly unstable through
the boiling period: back to the drawing board!

What does a CO/CO2 plot look like for the WFP Wood Rocket with skirt cited
in your "Initial Development of a Charcoal Rocket Stove" report?

Thanks for the stimulating graphs.

Dean presents graphed plots for the levels of CO and CO2 during one test
each of the charcoal burning rocket stove and Jiko-type charcoal stove from
Ghana.  A higher level of CO2 suggests a higher burn rate of fuel.
