Dear Everyone

>True, "Air pollution represents a major threat to public health in Ulaanbaatar, and reductions in home heating emissions should be the primary focus of future air pollution control efforts". But that is because the central heat and power plant's emissions have been reduced dramatically.

I beg to differ. The combined heat and power (CHP) plants are 4 in number. Station 1 closed long ago.
Station 2 was converted to a coal semi-coking plant several years ago.
Station 3 is 156 MW and is not a major source of PM emissions in the city.
Station 4 is 540 MW and has a 250m tall chimney which emits into the air stream passing over the city’s inversion layer. There is virtually nothing from No.4 reaching the city’s air.
Station 5 has just been approved and emits nothing.

During peak demand in summer for air conditioning and so on, the PM2.5 level in the city is 12-15 microgrammes per cubic metre proving that once space heating is removed, there is nothing from the power stations.

There are several majors sources:
Vehicles
Fugitive dust from the Gobi and
Power station ash dumps,
Street dust
Low pressure boilers
High pressure boilers such as apartment buildings
Domestic stoves

Domestic stoves were the largest contributor. They have dropped in importance.  Now it is low pressure boilers. I hear that two new models designed by the Stove Development Centre (actual product development!) will be introduced to the market this year. The SDC is attached to the SEET Lab and headed by the Mongolian University of Science and Technology and the Energy Research Centre (Min of Energy).
