【 摘 要 】

The U.S. Department of Energy (DOE) National Energy Technology Laboratory (NETL) and Frontier Geosciences, Inc. (FGS) collaborated in the investigation of sampling techniques that measure total and speciated forms of mercury (Hg) in flue gas. The FGS techniques investigated are referred to as the Frontier Sorbent Mercury Speciation (FSMS) method and the Sorbent Total Mercury (STM) method (Prestbo et al. 2001). Testing was conducted over five consecutive days during the week of March 27, 2000, on the 500 lb/hr pilot-scale coal combustion facility located at NETL-Pittsburgh. As a standard for comparison with the FSMS and STM methods, a standardized, draft ASTM method (ASTM 1998), referred to as the Ontario-Hydro (O-H) method, was run simultaneously at the outlet of the pilot unit baghouse. For each O-H sample, two FSMS mercury speciation traps and one STM trap were run. Following sampling, FGS analyzed the FSMS and STM samples, and NETL analyzed the O-H samples. These analytical results from FGS and NETL were combined with sampling data to calculate flue gas mercury concentrations and were then compared. This report presents the results of that comparison.
