| 英文摘要 | Coal-fired power plants are important sources of polycyclic aromatic hydrocarbon (PAH) emissions in the world. The effects of various air pollution control devices (APCDs) on PAH emissions were investigated by analyzing samples from inlets and outlets of APCDs in six coal-fired power plants (A-F) and two coal-fired industrial boilers (G and H). The APCDs were electrostatic precipitators (ESPs), wet flue gas desulfurization systems (WFGDs), and wet ESPs (WESPs). The PAH congener patterns for the coal-fired plants were similar. Gas-phase PAHs were dominant in flue gases, and the most abundant PAH was naphthalene. Three- and four-ring PAHs were dominant in fly ash. Positive correlations were found between the PAH and total organic carbon contents of fly ash (R-2 0.87) and slag (R-2 0.92). Plants D-F, equipped with low-low-temperature ESPs (LLT-ESPs) and WESPs discharged the lowest PAHs. Circulating water was an important source of PAHs in the desulfurization except in plant A. which used desalinated seawater rather than circulating water in the desulfurization process. WESPs decreased PAH concentrations by an average of 20.67%, which can be spread to other plants to reduce PAHs. (C) 2020 Elsevier B.V. All rights reserved. |
