Patent DE-3939197-A1 (DE)
IPC: F23J15/00
Filed: 1989-11-27
Abstract: The method for reducing the nitric oxide concentration in the waste gas flow of combustion processes consists of the introduction of chemicals, e.g. ammonia, sal ammoniac, urea, calcium cyanamide, into the waste gas flow, wherein the waste gas flow is marked by an additional compulsorily produced strong turbulence and the waste gas flow is compressed prior to this turbulence zone. The introduction of the treatment medium is effected shortly before the turbulence zone and the waste gas flow is relaxed and calmed subsequent to the turbulence zone. In order to implement this method, a furnace is provided which comprises a grate and a waste gas flue consisting of an ascending waste gas flue and a descending waste gas flue adjoining the latter. The current flow of the waste gas flow is substantially S-shaped proceeding from the furnace grate to the downwardly directed waste gas flue, wherein the change of direction in the lower area is substantially smoother than in the reversing space. In the upper portion the waste gas flue the waste gas flow is compressed by means of corresponding inclination and consequent constriction of the cross section of the waste gas flue. Spray nozzles are provided at the commencement of the upper portion of the ascending waste gas flue in order to introduce chemicals. The introduction of the chemicals is effected shortly before the compression and the production of strong turbulence.
