  • Method for operating flue gas purification system
    Patent number: 11441774
    Abstract: A method for operating a flue gas purification system, comprising, in the flue gas purification system, equipped with a boiler which can burn oil fuel and coal fuel either simultaneously or switching therebetween, a denitration equipment having a reducing agent injector and a catalytic reactor, an inlet flue to guide flue gas discharged from the boiler to the denitration equipment, an outlet flue to guide flue gas discharged from the denitration equipment, a bypass flue which can guide flue gas from the inlet flue to the outlet flue so as to bypass the denitration equipment, and a bypass damper, opening the bypass damper and burning oil fuel in the boiler being in condition not yet suitable for coal combustion to allow the flue gas discharged from the boiler to dividedly flow to the denitration equipment and the bypass flue, switching the oil fuel to coal fuel when the boiler is in condition suitable for coal combustion to burn the coal fuel in the boiler, closing the bypass damper after switching the oil fue
