Dear Stovers
I need a CO meter that will detect changes in a few seconds because the
whole point it to try to see what happens when we turn the stove down from a
high heat.
When the air supply is cut off, or mostly cut off, there is a long reaction
time when the heat stored in the wood and stove drives off gas for which
there is no available oxygen and I expect the CO level to rise dramatically.
After a time everything slows down and this burn very well again. I am
trying to document the CO conditions in the hot-turned-down-state and the
starved-for-air state.
On another note:
I am happy to report that the can making company has pitched up with two
daditional sizes for me: a 40 litre and a 50 litre can, both 358 in diameter
made from 0,6mm material which is 4 times as stiff as the present unit.
One of Marlis' concerns (and ours) is that the 25 litre can stove didn't
weigh enough to stay still while stirring maize meal porridge. Apparently
there is a stove in Kenya that picked up the nickname 'walking stoke'
because it was so light it moved around a lot when the cook was stirring!
Regards
crispin
