The invention relates to a flue gas pipe ( ) of an incineration plant, comprising a reaction zone ( ) for breaking down harmful substances and a heat exchanger ( ) for cooling the flue gas (R) which is mounted downstream and fitted with a dioxin catalytic converter ( ). The dioxin catalytic converter ( ) in the heat exchanger ( ) makes it possible to prevent the renewed formation of dioxins by de novo synthesis when the temperature drops.

Flue gas pipe and method for treating flue gas

A method for a regenerative heat exchanger for the treatment of pollutant-containing waste gases which are in a heat exchange with another medium. The heat exchanger includes stationary or rotating storage masses which are at least partially of catalytic material and to which a reduction agent is supplied from the hot side thereof. A penetration of the reduction agent into the flue gas flow can be prevented by supplying the reduction agent directly to the catalyst separately from the pollutant-containing waste gases and without coming into contact with the remaining heating surfaces. For this purpose, a nozzle arrangement having at least one arm and extending over the entire radius of the heat exchanger may be arranged in both hood sides of the heat exchanger.
