Abstract

The removal apparatus of trace harmful substances in exhaust gas is disposed with; a denitration device equipped with a denitration catalyst layer having a function of removing nitrogen oxide in exhaust gas in order from the upstream side to oxidize metallic mercury, in an exhaust gas flow channel discharged from a combustion facility; an air preheater for heat-exchanging air for combustion of the combustion facility to exhaust gas; a dust removal device having a bag filter containing oxidation catalysts for metallic mercury; and a desulfurization device for removing sulfur oxide in exhaust gas. The bag filter may be disposed in front of the desulfurization device.
