    • A continuous steam generator including a combustion chamber with a plurality of burners for fossil fuel is provided. A vertical gas duct is connected downstream of the combustion chamber on the hot gas side, in an upper region via a horizontal gas duct. The outside wall of the combustion chamber is formed from evaporation pipes which are welded together in a gas-tight manner and mounted upstream of a water separator system on the flow medium side and from superheater pipes which are welded together in a gas-tight manner and mounted downstream of the water separator system. The water separator system includes a plurality of water separation elements, each element includes an inlet tube which is connected to the respective upstream evaporation for tubes, which extend into a water evacuation tube. A distributer element is arranged on the evaporator side between the respective water separator element and the inlet collector.

    • 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.
