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 steam generating boiler having a matrix means for reducing combustion volume. Matrix means is placed in the combustion furnace of a steam generating boiler, preferably downstream of fuel and oxidant stream. Matrix means produces a shorter combustion envelope than that of a conventional boiler, allowing for reduced volume steam generating boilers.

摘要： The present invention concerns a processing furnace used by the oil industry to heat feedstocks that are to be treated thermally, which is provided with bi-pivotal support columns to carry the radiation exchange tubes which form the coil of radiation exchange tubes. The support columns are provided with a lower bearing and an upper bearing means, which pivot, respectively, on a lower support and an upper guide, in such a way that all the stresses from the support and the radiation exchange tubes are transmitted to the base, causing no thermal stress from bending momentum to be transmitted to the base of the furnace.
