Dear Friends
If you want to see what the baseline stove emissions in the
Johannesburg/Pretoria area look like, and why we at the SeTAR Centre are
working on this as a priority. The fuel is Witbank D (a bituminous high-ash
coal) which is pretty easy to ignite.

The fuel responds well to TLUD ignition (?88% reduction in PM) though it
takes longer to get to a no-smoke stage. Cooking can however be started
sooner than when using a BLUD ignition. After the coal is coked, people take
the burning device inside their homes. At that stage it produces nearly no
PM at all - extremely low - but quite a lot of CO. The CO level varies
greatly based on how the holes are patterned.
Regards
Crispin
