| 英文摘要 | Residential coal combustion is an important heating source in rural China and a major source of particulate matter (PM) and elemental carbon (EC) during winter haze episodes. However, how combustion temperature governs the physicochemical properties of individual particles from coal combustion remains poorly understood. This study investigated emissions from a typical bituminous coal combusted at 400, 600, and 800 degrees C. Results showed that temperature dramatically altered pollutant formation: the emission factor of organic carbon (OC) decreased from 20.99 g/kg to 2.38 g/kg with rising temperature, whereas that of EC increased from 0.76 g/kg to 3.85 g/kg. Single-particle analysis further revealed that both the abundance of EC particles (which increased from 15% to 89%) and the size of EC aggregates (which increased nearly threefold) increased significantly with rising temperature, confirming that higher temperatures directly promote the growth and aggregation of EC particles. Notably, metal particles exhibited distinct volatilization and transformation behaviors. For instance, Zn exists in the form of mineral particles at low temperatures, droplet-like Zn-rich particles at medium temperatures, and nanosized crystal at high temperatures. This research underscores combustion temperature as a fundamental driver controlling the physicochemical properties of coal combustion particles. It suggests that stove upgrades focusing solely on increasing combustion temperature, without complementary fuel or emission control measures, may lead to unintended adverse consequences for climate and public health. |
