Migration and Emission Characteristics of Trace

2016-7-21  Trace elements (TEs) emitted from coal-fired power plants have caused widespread concern. The onsite investigation of TEs emission from a Chinese 660 MW pulverized coal (PC) boiler equipped with selective catalytic reduction (SCR), electric submersible pump (ESP), wet flue gas desulfurization (WFGD), and wet electrostatic precipitator (WESP) was conducted by using U.S.
