“…After being emitted from a facility's coal-fired furnace, Cd, Cr, Pb and their compounds accompanied with fine fly ash in the flue gas can be partly removed to ash and desulfurization slurry by downstream PM and SO 2 control devices, such as electrostatic precipitators (ESPs), fabric filters (FFs), cyclones, wet scrubbers, as well as wet flue gas desulfurization (FGD) systems (Yi et al, 2008;Tian et al, 2010). The remaining flue gas will be emitted into the atmosphere through the stack.…”

“…Over the past decades, extensive studies have been conducted on trace element in coal, especially trace element emissions from coal-firing power plants [18][19][20][21]. It is reported that the emission of trace elements is influenced by the thermodynamic properties of elements, the forms of elements in the feed fuel as well as the combustion environment [22][23][24][25][26][27].…”

Coal gangue is one of the largest industrial residues. It has high ash content, low carbonaceous content, and heating value. Meanwhile, it has some trace elements. Large quantities of coal gangue cause serious environmental problems by polluting the air, water, and soil as well as occupying a tremendous amount of land. Now, coal gangue utilization is a matter of great concern and has attracted wide interest. However, some toxic trace elements in coal gangue should be paid more attention during the utilization of coal gangue. In this article, the modes of occurrence and the leaching characters of trace elements in coal gangue were introduced according to the result of the sequential extraction method and the leaching method. The release character of trace elements during combustion of coal gangue and the environmental implication of trace elements in coal gangue were also discussed. The sulfide-bound trace elements are dominant form in coal gangue. Leaching behavior of trace elements from coal gangue is affected by many factors. Different trace elements presented different transformation behaviors. Trace elements in coal gangue could release out and produce environmental implication in various degrees, depending on the type of trace elements.

“…Power plant emissions include particulate matter, sulfur dioxide, nitrogen oxide and other pollutants, which migrate, react and interact with other fixed or mobile sources of atmospheric pollution, thereby becoming one of the important causes of frequent foggy and hazy weather periods. Inhalable particles (PM 10 ) and fine particulate matter (PM 2.5 ) can directly enter the human respiratory tract and lungs, potentially causing cancer, heart attack, and a number of respiratory ailments (Zhuang and Biswas, 2001;Yi et al, 2008). van Donkelaar et al (2010) and Zhang and Cao (2015) showed the real necessity for taking measures to control this problem using satellite instruments and a global 3D chemical transport model (CTM), which was obtained by coinciding aerosol vertical profiles by means of GEOSChem simulations.…”

In the present study, the in uence of di erent particle aggregation models on the y ash particle aggregation process of a turbulence aggregation device has been studied. The in uence of an interparticle repulsive potential energy barrier, U max , on the rate of aggregation was considered, and capture e ciency, f (α), was introduced to correct the ideal turbulence aggregation kernel. The simulation results of an ideal turbulence aggregation model and a corrected turbulence aggregation model were compared to the experimental results, and showed that the error between the ideal turbulence aggregation model and experimental results was approximately 8%; whereas, the error between the corrected turbulence aggregation model and experimental results was only 3%. Brownian aggregation cannot be ignored in the turbulence aggregation of the particles less than 2 µm in diameter. The coupled corrected turbulence aggregation and Brownian aggregation model coincided well with the experimental results.
