Effects of Temperature and Chemical Speciation of Mineral Elements on PM10 Formation during Zhundong Coal Combustion

Particulate matter (PM) pollution from coal combustion is a leading contributor to the influence of atmospheric visibility, photochemical smog, and even global climate. A drop tube furnace was employed explore effects temperature chemical speciation mineral elements on PM formation during Zhundong coal. Chemical fractionation analysis (CFA), X-ray fluorescence (XRF), inductively coupled plasma-atomic emission spectrometry (ICP-AES) were used investigate physical characteristics solid samples. It can be indicated that similarly sized particles yielded more PM10 when increased 1000 1400 °C. fractionated with deionized water, ammonium acetate, hydrochloric acid, pulverized coal, after fractionation, burned study different occurrence forms, such as water-soluble elements, exchangeable ion acid soluble acid-insoluble particles. The results show salts play an important role in forming ultrafine (PM0.2); Fe, Ca, other organic form are distributed flue gas through evaporation combustion. When decreases, PM1 formed homogeneous nucleation heterogeneous condensation, resulting distribution these two PM1. Different methods do not significantly affect Si Al PM1–10 process.
