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
