Resolving emission factors and formation pathways of organic gaseous compounds from residential combustion of European brown coal.
Combust. Flame 265:113485 (2024)
Residential combustion of brown coal can be an important source of ambient air pollution in areas with abundant brown coal deposits, such as Eastern Europe or China. The exhaust emission contents may vary regionally depending on the fuel composition, calling for detailed characterization of emissions from different coal types. In this work, the organic gaseous emissions of European brown coal combusted in a modern chimney stove -type residential appliance were measured by a proton transfer reaction time-of-flight mass spectrometer. Of three consecutive batches of brown coal briquettes, the first batch produced two-fold emission (144 ± 52 mg/MJ) of organic gaseous compounds (OGCs) compared to the later batches (71 ± 35 mg/MJ). The compositions between the batches were, however, relatively similar. Carbonyls accounted for 36 ± 3.0% of the identified emission factors, while aromatic hydrocarbons and oxygenated aromatic compounds contributed 19 ± 3.4% and 16 ± 1.8%, respectively. The complex and overlapping chemical processes within batch combustion were exposed by non-negative matrix factorization, giving insight into the temporal variation in the formation pathways of the OGCs. The OGCs were separated into five factors revealing the chemical fingerprints of the main processes leading to formation of, for example, substituted or single-ring aromatic hydrocarbons. Oxygenated aromatic compounds were related to a distinct factor, which was proposed to form specifically from decomposition of the lignin residues of the brown coal. OGCs from brown coal combustion were estimated to have notable secondary particle formation potential: in photochemical conditions, they may double the organic particulate emission, while reactions in dark conditions may lead to excessive nitrophenol formation.
