Beschreibung
Zusammenfassung:	A denitration device that has: an inlet duct having a flowpath that causes exhaust gas from a boiler to flow in the horizontal direction; a connecting duct having a flowpath that changes the flow of exhaust gas from the horizontal direction to the vertical direction; and a reactor duct having a flowpath that causes the exhaust gas to flow in the vertical direction. The reactor duct has therein, in order along the exhaust gas flow, a screen plate, a denitriding agent supply line system, and a fixed bed including a denitriding catalyst. The denitriding agent supply line system has: a heat exchange line for heating the denitriding agent using the heat held by the exhaust gas; a transportation line for supplying the denitriding agent heated by the heat exchange line to a nozzle; and the nozzle, for injecting the denitriding agent supplied via the transportation line to the reactor duct.
