Title (DE) VERFAHREN UND VORRICHTUNG ZUR KATALYTISCHEN ENTSTICKUNG VON GASSTRÖMEN AUS GROßFEUERUNGSANLAGEN
(EN) METHOD AND DEVICE FOR CATALYTIC DENITRIFICATION OF GAS FLOWS FROM LARGE COMBUSTION PLANTS
(FR) PROCÉDÉ ET DISPOSITIF DE DÉNITRURATION DE FLUX DE GAZ ISSUS D'INSTALLATIONS DE COMBUSTION DE GRANDE TAILLE
Abstract:
(DE) Es werden ein Verfahren sowie eine Vorrichtung zur katalytischen Stickoxidentfenung aus Gasströmen von Großfeuerungsanlagen, insbesondere aus Kraftwerksabgasen, beschrieben. Um auf wirtschaftliche Weise eine effektive Entstickung auch bei so genannten "Oxyfuel"-Anlagen zu erreichen, die mit Sauerstoff als Brenngas arbeiten, wird vorgeschlagen, die katalytische Behandlung nicht im drucklosen Gasstrom, sondern in einem auf einen Druck von mindestens 2 bar verdichteten Gasstrom durchzuführen.
(EN) The invention relates to a method and to a device for catalytic denitrification of gas flows from large combustion plants, particularly of power plant exhaust gases. In order to achieve effective denitrification in an economically feasible manner, even for so-called "oxyfuel" plants using oxygen as a combustion gas, the invention proposes that the catalytic treatment is performed not in the zero-pressure gas flow, but in a gas flow compressed to a pressure of at least 2 bar.
(FR) L'invention concerne un procédé et un dispositif d'élimination catalytique des oxydes d'azote contenus dans des flux de gaz issus D'installations de combustion de grande taille, en particulier dans les gaz de combustion d'une centrale électrique. L'invention vise à réaliser une dénitruration économique et efficace même dans le cas d'installations "d' oxycombustion" qui utilisent de l'oxygène comme gaz de combustion. A cet effet, le traitement catalytique n'est pas effectué dans le flux de gaz sans pression, mais dans un flux de gaz comprimé à une pression d'au moins 2 bars.
