Abstract

An exhaust gas treatment apparatus (4) is provided with: a dust collector (43) provided to a flue (3) through which an exhaust gas flows; a chemical supply unit (42) for supplying an exhaust gas treatment chemical to a chemical supply position (P1) between the dust collector (43) and a combustion chamber (2) in the flue (3); a collected dust ash conveyance unit (44) for conveying collected dust ash collected by the dust collector (43) toward a collected dust ash supply position (P2) between the combustion chamber (2) and the dust collector (43) in the flue (3) along an auxiliary route (441) different from the flue (3); and a collected dust ash heating unit for heating the collected dust ash, the collected dust ash heating unit being provided in the auxiliary route (441). Through this configuration, adhesion of collected dust ash in the auxiliary route (441) can be suppressed.
