This study characterized emissions of particulate matter (PM), volatile organic compounds (VOCs), heavy metals, and anions from Mongolian bituminous coals in a controlled heating experiment. Three coal samples from Alag Tolgoi (coal 1), Baganuur (coal 2), and Nalaikh (coal 3) were combusted at a constant heat flux of 50 kW/m² using a dual-cone calorimeter. The coal samples were commonly used in ger district of Ulaanbaatar, Mongolia. PM emission factors were 1122.9 ± 526.2, 958.1 ± 584.0, and 472.0 ± 57.1 mg/kg for coal samples 1, 2, and 3, respectively. PM with a diameter of 0.35⁻0.45 µm was dominant and accounted for 41, 34, and 48% of the total PM for coal samples 1, 2, and 3, respectively. The emissions of PM and VOC from coals commonly used in Ulaanbaatar, Mongolia were significant enough to cause extremely high levels of indoor and outdoor air pollution.
本研究采用控制加热实验，对来自蒙古烟煤的颗粒物（PM）、挥发性有机化合物（VOC）、重金属和阴离子排放进行了特征描述。使用双锥量热计，以 50kW/m² 的恒定热通量对来自阿尔泰托罗戈伊（煤 1）、巴彦乌勒盖（煤 2）和纳来哈（煤 3）的三个煤样进行了燃烧。这些煤样在蒙古乌兰巴托的蒙古包区被广泛使用。对于煤样 1、2 和 3，PM 排放因子分别为 1122.9±526.2、958.1±584.0 和 472.0±57.1mg/kg。直径为 0.35-0.45µm 的 PM 占主导地位，分别占煤样 1、2 和 3 总 PM 的 41%、34%和 48%。蒙古乌兰巴托常用煤的 PM 和 VOC 排放足以造成极高水平的室内外空气污染。
