[Stoves] Ulaanbaatar Air Quality

[Crispin Pemberton-Pigott]

Dear Teddy

 

Generally speaking the locally made ones are poorly designed, leaky and have
a power spectrum and controllability that meets the local demand.  People
also know how to use them.

 

In Ulaanbaatar the artisanal stoves last from 5 to 10 years but highly
variable. They are quite good wood stoves, for which the brick lining is
removed.

 

If we could reliably get harder, smaller coal (size sorted) some could
operate for 12 hours without attention.

 

All the new (subsidized) ones are well made. They have to fix them free for
the first two years under warranty and so on. Several run way too hot so
they won't last 5 years. People generally want huge cooking and heating
power.

 

Regards

Crispin

 

 

Interesting discussion, sorry if this is a bit off the point but has anyone
done or heard of any new life cycle analysis research on the manufacturing
and distribution aspects of new stoves vis-a-vis the ones made in brand new
in factories as opposed to the ones made by hand at a village level with
recycled materials? 

 

What impacts of localized pollution does this have do you think? 

 

Teddy
