摘要： A method and a boiler for decreasing the amount of nitrogen oxides in flue gases of a boiler, which flue gases are generated in the combustion of fuels and air. The boiler has a water circulation system comprising superheaters and a furnace for combustion of fuel and for generating flue gases that contain nitrogen oxides, which flue gases mainly flow upwards in the furnace and further to the superheater zone and via other heat recovery surfaces of the boiler out of the boiler, and a nitrogen oxides reducing agent is introduced into the flue gases. The nitrogen oxides reducing agent is introduced into the flue gases prior to the superheater zone, after the temperature of the flue gases is decreased by at least one heat exchanger that is located upstream of the nose of the boiler and upstream of the introduction of the nitrogen oxides reducing agent.

摘要： A chemical recovery boiler (100), including a furnace (1), comprising a front wall (2), a back wall (3), and the back wall (3) comprising a nose arch (4). The boiler further comprises at least one superheater (5) arranged in upper part of the furnace (1), and a screen pipe system (6), comprising an obliquely arranged screen pipe section (7) positioned before/under the at least one superheater (5) in the furnace (1). The obliquely arranged screen pipe section (7) comprises screen pipes (8) ascending (i) either from the front wall (2) to the back wall (3), and arranged to turn back in a turn (13) from the back wall (3) and extend obliquely upwards from the back wall (3), or (ii) from the back wall (3) to the front wall (2), and arranged to turn back in a turn (13) from the front wall (2) and extend obliquely upwards from the front wall (2). The screen pipe system (6) further comprises a vertically arranged screen pipe section (9) extending from the obliquely arranged screen pipe section (7). The screen pipes (8) of the vertically arranged screen pipe section (9) are arranged to extend parallel with the at least one superheater (5) in upper part of the furnace (1).

摘要： The present invention relates to a method and a boiler for decreasing the amount of nitrogen oxides in flue gases of a boiler, which flue gases are generated in the combustion of fuels and air. The boiler has a water circulation system comprising superheaters (8) and a furnace (1) for combustion of fuel and for generating flue gases that contain nitrogen oxides, which flue gases mainly flow upwards in the furnace and further to the superheater zone and via other heat recovery surfaces of the boiler out of the boiler, and a nitrogen oxides reducing agent is introduced into the flue gases. It is essential that the nitrogen oxides reducing agent is introduced into the flue gases prior to the superheater zone, before which the temperature of the flue gases is decreased by means of at least one heat exchanger (15) that is located in the flue gas flow upstream of the introduction of the reducing agent, for obtaining a suitable temperature window in the flue gas flow in order to reduce nitrogen oxides.
