According to the U.S. Energy Information Administration's statistics, in the 2006–2016 period, approximately 42% of the electricity consumed in the U.S.A was produced by coal combustion (U.S. Energy Information Administration, 2018).The coal combustion process generates various types of residues such as fly ash, bottom ash, …

The main component of desulfurized steel slag is calcium sulfate, which is similar to desulfurized gypsum. Steel slag is originally strong alkaline, but it becomes neutral and weak acidic substances after absorbing SO 2 in the process of flue gas desulfurization (Meng et al., 2018, 2019; Ying et al., 2021).

RM, DG and FA were respectively provided by an aluminum plant, a steel factory and a power plant in Yangquan, China. Cement used in this test was commercially available PⅠ 42.5 ordinary portland cement. The aggregate was the commercially available Chinese ISO standard sand. Table 1 shows the chemical components of RM, DG, FA …

The thermal treatment duration is another important factor affecting Hg release. In fact, as shown in Fig. 2, the Hg release ratio of FGD gypsum increased drastically with the thermal treatment time.In particular, the average Hg release ratio increased from 3.25 ± 4.96% to 19.20 ± 7.35%, from 13.25 ± 6.97% to 37.56 ± 19.25%, …

The corrosion behaviors of pure titanium and its weldment welded by tungsten inert gas (TIG) welding in simulated desulfurized flue gas condensates in thermal power plant chimney were investigated using potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and immersion tests. The effects of heat input and …

In China, the wet limestone-gypsum process is the most widely adopted FGD method due to its high efficiency and low cost [1], [2]. A limestone slurry is used as the absorbent to remove SO 2 in the flue gas and produce gypsum. The desulfurized flue gas leaves the FGD saturated with water vapour and entrains a large number of droplets.

The control, namely the hemihydrate gypsum without desulfurized ash, provides with 0.47 water requirement. However, the hemihydrate gypsum with 8% desulfurized ash displays a water requirement of 0.49 and it is obvious. Conclusions. Mixtures of hemihydrate gypsum and desulfurized ash were prepared and their …
