Frontiers of Environmental Science & Engineering 2019, Volume 13, Issue 1, doi: 10.1007/s11783-019-1087-6

Abstract:

Estimated anthropogenic Hg emission was 11.9 tons in Pearl River Delta for 2014.

Quantifying contributions of emission sources helps to provide control strategies.

More attentions should be paid to Hg deposition around the large point sources.

Power plant, industrial source and waste incinerator were priorities for control.

A coordinated regional Hg emission control was important for controlling pollution.

Frontiers in Energy 2021, Volume 15, Issue 1,   Pages 112-123 doi: 10.1007/s11708-020-0682-3

Abstract: The mercury emission was obtained by measuring the mercury contents in flue gas and solid samples in, while the mercury was enriched in fly ash and captured by the precipitator in CFB boiler.As the coal factor increased, the mercury emission to the atmosphere decreased.As the unburned carbon content increased, the mercury adsorbed increased.The capacity of adsorbing mercury by fly ash was directly related to the particle size.
