This study estimated the stability of mercury (Hg) compounds in coal combustion residuals (CCRs) from Hybrid Filter (HF) systems in coal power plants. The HF system, which was designed for the control of fine particulate matter, was found to have a performance to have a co-benefit effect by controlling mercury compounds in flue gas. The cascade impactor was used to measure the control efficiency of dust by particle size at the inlet and outlet of the HF system. Then, the particle size distribution of the HF fly ash was estimated by comparing the concentrations of the total suspended particles. The sequential extraction procedure consisting of five steps was applied to the CCRs: fly ash from the electrostatic precipitator and HF, and gypsum from the flue gas desulfurization. The behavior of Hg was affected by the development of air pollution control devices (APCDs), and as a result, we identified fly ash having a different form compared to previously reported data. The residual Hg fraction increased to a greater extent compared to the mobile Hg fraction in HF fly ash compared to ESP fly ash; the fraction estimated to be Hg<sup>0</sup> and Hg<sup>0</sup>-amalgam decreased. FGD gypsum contained a higher ratio of the mobile Hg fraction than the fly ash collected from ESP and HF. Information on the stability of Hg compounds regarding developed APCDs needs to be considered for the recycling and disposal of CCRs.
