Abstract
An exhaust gas purification device is disclosed provided with a denitration catalyst for reducing and removing nitrogen oxides in exhaust gas using ammonia as a reducing agent in a gas flow passage through which the exhaust gas discharged from a boiler flows, and which injects ammonia into the exhaust gas flowing through the gas flow passage on an upstream side of the denitration catalyst, including multiple disturbing plate support members, and a disturbing plate. The multiple disturbing plate support members are fixedly provided on a downstream side of the denitration catalyst and arranged extending linearly in a flow path cross section to cross the gas flow passage. The disturbing plate includes an exhaust gas flow facing surface exposed on an upstream side and is fixed to the disturbing plate support members so that a position thereof in the flow path cross section can be changed.
