Abstract

Abstract

Nowadays, the retrofit of ultra-low emission has been finished in most coal-fired power plants, and are in process in iron and steel plants in China. The concentration of filterable particulate matters (FPM) has been greatly reduced and condensable particulate matters (CPM) have aroused more attention. The fraction of organic matter in CPM emitted from coal-fired power plants (CFPPs) and iron and steel plants remained controversial, which was important to understand the formation mechanism and to promote the emission control of CPM. We collected CPM samples by in-direct dilution method in eight CFPPs and three iron and steel plants (including two sintering and one coke making plants), and specific compositions and fraction of organic matter in CPM were analyzed. The results showed that the concentration of organic compositions from CFPPs was 0.082 mg/m³(0~0.331 mg/m³) and 0.060 mg/m³(0~0.254 mg/m³) at the inlet of flue gas desulfurization and stack, accounting for 4.95% and 10.1% of total CPM content, respectively. For iron and steel plants, the concentration and proportion of organic matter were higher in comparison with those from CFPPs, which were 1.9 mg/m³(0.408~3.98 mg/m³) and 0.382 mg/m³(0.149~0.572 mg/m³) at the inlet of flue gas desulfurization and stack, accounting for 22.2% and 11.1% of total CPM content respectively. Major compositions of organic matter in CPM from CFPPs were esters, whereas alkanes and alkanoic acids were the major composition in CPM from iron and steel plants. In a word, the fractions of organic matter at two kinds of stationary sources were relatively low, more attention should be paid on controlling its inorganic gas precursors.
