Residential
coal combustion is a significant contributor to particulate
urban air pollution in Chinese mega cities and some regions in Europe.
While the particulate emission factors and the chemical characteristics
of the organic and inorganic aerosol from coal combustion have been
extensively studied, the chemical composition and nonmethane organic
gas (NMOG) emission factors from residential coal combustion are mostly
unknown. We conducted 23 individual burns in a traditional Chinese
stove used for heating and cooking using five different coals with
Chinese origins, characterizing the NMOG emissions using a proton
transfer reaction time-of-flight mass spectrometer. The measured emission
factors range from 1.5 to 14.1 g/kgcoal for bituminous
coals and are below 0.1 g/kgcoal for anthracite coals.
The emission factors from the bituminous coals are mostly influenced
by the time until the coal is fully ignited. The emissions from the
bituminous coals are dominated by aromatic and oxygenated aromatic
compounds with a significant contribution of hydrocarbons. The results
of this study can help to improve urban air pollution modeling in
China and Eastern Europe and can be used to constrain a coal burning
factor in ambient gas phase positive matrix factorization studies.
