Document Type and Number:
Japanese Patent JP2637119
Kind Code:
B2
Abstract:
A denitration reactor comprises an entrance duct portion (1) into which exhaust gas (G) from a boiler flows, an intermidiate duct portion (10) incorporating therein a catalyst layer (4) for denitration, and an exit duct portion (5) connected to the intermediate duct portion (10). The intermediate duct portion (10) is so disposed that an axis thereof is perpendicular to an axis of the entrance duct portion (1). The reactor further comprises a bent portion (2) for connecting the entrance duct portion (1) to the intermediate duct portion (10), and a flow controller (3). The wall (2a) of the bent portion (2) is inclined with an inclination angle theta and extends from a section on which one wall (10a) of the intermediate duct portion (10) crosses a surface of a floor (1a) of the entrance duct portion (1) to a section on which a plane including opposite wall (10b) of the intermediate duct portion (10) crosses a roof (1b) of the entrance duct portion (1). The flow controller (3) is so disposed in the intermediate duct portion (10) that an exhaust gas introduction surface of the flow controller (3) coexists with the floor (1a) of the entrance duct portion (1) on the same plane.
