Abstract


To reduce levels of outdoor air pollution, new energy-efficient solid fuel
stoves have been offered for sale in the ger regions of Ulaanbaatar, the
capital city of Mongolia. These energy-efficient stoves should use less fuel
than the traditional stove and emit a tenth of the pollutant emissions.
However, because the stoves were only broadly introduced in August
2011, limited documented information exists of actual household fuel
and stove use behaviours or the impact of those behaviours on emissions.
During the 2011-2012 heating season (October–March), we evaluated
stove use behaviour in a small subset of ger households with either
traditional or an energy-efficient stove. Relying on a combination of
in-person interviews and stove use monitor (SUM) technology, we
observe that stove use behaviour can vary substantially between
households and identify three main burn cycles related to the use of
the energy-efficient stove, which may impact the degree to which PM
emissions can be mitigated. We show how SUMs can play a key role in
identifying the frequency of ignition and refueling events and how this
data in combination with household surveys, can characterise the impact
user behaviour can have on stove emissions.
