ABSTRACT:
An apparatus for removing nitrogen oxides from a flue gas comprises a first stage of injecting ammonia in a combustion flue gas and then hydrogen peroxide thereto, thereby decomposing nitrogen oxides in the combustion flue gas to nitrogen and water by gas phase reduction, and a second stage of passing the combustion flue gas leaving the first stage through a bed of catalyst whose temperature is controlled by cooling water passing through a cooling pipe provided through the bed of catalyst, thereby conducting decomposition of excess ammonia exiting from the first stage and further reaction of nitrogen oxides at the same time.
