Abstract

A denitration apparatus, comprising an entrance duct (1) having a flow path for flowing an exhaust gas from a boiler in the horizontal direction, a joint duct (2) having a flow path for changing the flow of the exhaust gas from the horizontal direction to the vertical direction, a reactor duct (6) having a flow path for flowing the exhaust gas in the vertical direction, a screen plate (3), a denitration agent supply line system (7), and a fixed bed, wherein the fixed bed comprises a denitration catalyst, the screen plate (3), the denitration agent supply line system (7) and the fixed bed are set in this order along the flow of the exhaust gas in the reactor duct (6), the denitration agent supply line system (7) comprises a heat exchange line (8) for warming a denitration agent with the heat possessed by the exhaust gas, a transportation line (9) for supplying the denitration agent warmed by the heat exchange line (8) to a nozzle (10), and the nozzle (10) for injecting the denitration agent supplied through the transportation line (9) into the reactor duct (6).
