Experimental Study of Mercury Releasing Characteristics of Coal Fly Ash under Mild Thermal Condition

Abstract:

Under mild thermal condition, mercury releasing characteristics and its morphological features transformation of fly ash sample, which is obtained from the exit of air pre-heater of one power plant in eastern China, has been studied in the paper. The experiment shows that under mild thermal condition, the temperature range of fly ash mercury releasing is about 200 °C ~ 800 °C. It reaches the first peak at about 300 °C and it reaches the second peak at about 600°C. Moreover, most sample elemental mercury is Hg0. The fly ash sample in which mercury emissions and unburned carbon content have no obvious relationship.
