Definitions

  • NO x must be deposited in the exhaust gas down to less than 200 mg / m 3 .
  • catalyst arrangements should preferably consist of coiled flat steel profiles which have the corresponding active surfaces.
  • the invention is not limited to the embodiments shown and described in detail above, but numerous modifications are possible without deviating from the basic idea of providing smoke pipes with internal profiles on which catalyst masses are applied in order to reduce the NO x .
  • This helical catalytic converter arrangement can be arranged to be movable in order to simultaneously clean the flue pipes.
  • the attached sketch shows: with (1) a boiler; with (2) the flue pipes; with (3) those in the flue pipes

Abstract

Une disposition légale prescrit la séparation de NOx dans le gaz de fumées de chaudières à des quantités inférieures à 200 mg/m3. A cet effet, une solution connue est de faire passer les gaz de fumées par des catalyseurs. Afin de faciliter une telle séparation de NOx, la présente invention propose de doter l'intérieur des tubes de fumée (2) de la chaudière (1) de surfaces de catalyse (3). Ces dernières peuvent être placées hélicoïdalement dans les tubes de fumée (2) tout en étant mobiles à l'intérieur de ceux-ci.
