Heating Stoves


Air pollution levels in Ulaanbaatar, Mongolia’s capital, are among the highest in the world. Coal-­burning heating stoves used in the Gers (traditional dwellings) around Ulaanbaatar are a primary contributor to this pollution. Several efforts are underway to replace traditional heating stoves with improved low-­emission high-efficiency stoves. Testing protocols for these high-efficiency stoves are typically based on manufacturers’ recommended operating procedures.  So, white these procedures demonstrate the stoves’ optimal performance when operated in accordance with manufactures’ instructions, they may not be representative of actual field performance and emissions. The combination of stove design, fuel characteristics, and operational factors, along with the dynamic nature of the combustion process, leads to significant levels of variability and uncertainty in quantifying emissions. Therefore, selection of these high-­performance stoves must be based on extensive field observations and lab measurements. The objective of this project is to identify the key factors that influence stove performance (fuel efficiency and emissions) in the field and to quantify the impact of these factors.
