Fate and abatement of mercury and other trace elements in a coal fluidised bed oxy combustion pilot plant

Unburned carbon from coal combustion ash: An overview

“…High correlation coefficients were calculated for these relationships in 3 FBC power stations combusting 2 lignites and 1 bituminous coal. However, since FBC ashes contain usually high percentage of calcareous minerals, this could be another important factor enhancing the retention of Hg and acid-forming elements [283][284][285][286][287][288][289].

Heavy metal enrichment characteristics in ash of municipal solid waste combustion in CO2/O2 atmosphere

“…Only a minority of researchers have reported the heavy metals behavior under coal CO 2 /O 2 combustion (Zheng and Furimsky, 2003;Font et al, 2012;Zhuang and Pavlish, 2012). There have been some contradictory observations on the heavy metal emissions from coal CO 2 /O 2 combustion.…”

Effect of flue gas components on Hg0 oxidation and adsorption by modified walnut shell coke in O2/CO2 atmosphere

“…The proportion of three mercury species varies with the composition of flue gas. The studies on the release of mercury from oxy‐fuel combustion flue gas shows that the content of Hg 0 in oxy‐fuel flue gas is higher than that in air combustion flue gas . Due to the high volatility and low water solubility of Hg 0 , it is difficult to be removed by the conventional air pollutant collaborative control devices (APCDs).…”

“…The studies on the release of mercury from oxy-fuel combustion flue gas shows that the content of Hg 0 in oxy-fuel flue gas is higher than that in air combustion flue gas. [7][8][9] Due to the high volatility and low water solubility of Hg 0 , it is difficult to be removed by the conventional air pollutant collaborative control devices (APCDs). Therefore, it is very important to develop efficient mercury removal technology to remove Hg 0 in oxy-fuel combustion system.…”
