[Stoves] Ulaanbaatar Air Quality

[Crispin Pemberton-Pigott]

Dear Friends

 

The air quality of Ulaanbaatar is famously bad because of the ignition of
coal stoves. The majority of stoves have been swapped for very much cleaner
burning ones and the impact is dramatic.

 

Usually in November the city air has between 500 and 4000 µg of PM2.5

 

If you visit https://twitter.com/UB_Air you can see Prof Lodoysamba’s
twitter feed which Tweets the number every 3 hours, every alternate day.  

 

It has almost reached 600 but that is a far cry from two years ago.

 

There is a (slightly misleading) article from the Guardian at
http://www.theguardian.com/world/2013/oct/20/ulan-bator-killer-winter-stoves
which discusses the air quality issue.

 

It says the rise in patients with respiratory illnesses from 2004-2008 is
deteriorating air but it is far more likely to be the huge increase in
population – the air was the same from 2004-2008. The population went from
400k to 1.2m in 15 years. 

 

Anyway, publicity is not wrong when it comes to cleaner air!

 

Note the feedback from consumers. The photo is of one of the ‘approved’ new
stoves. It is a TLUD with controllable secondary and primary air. Note the
very large ring that can be removed to accommodate huge woks.  The materials
used are cast iron, sheet metal and ceramic.

 

Regards

Crispin
