A particulate separation system for accurate measurement of vapor-phase mercury in a flue gas stream uses an inertial gas sampling filter in which the skin temperature of the filter element is controlled to allow vapor-phase mercury measurements while minimizing measurement artifacts caused by: (1) mercury thermally desorbing off particulates into the gas stream; and (2) mercury being removed from the vapor phase by collection on particulate matter at the gas/particle separation interface.

Particulate separation system for mercury analysis

The apparatus comprises a NO reducing unit, a duct to receive a flue gas stream from said NO and reducing unit, and an activation source associated with the duct. In use, the activation source applies energy to the flue gas stream to facilitate the removal of contaminants from the flue gas stream. Further, the method comprises providing an activation source is downstream of a NO reducing unit. The activation source is then activated to facilitate the removal of contaminants from the flue gas stream.
