Abstract
Apparatus for removal of deleterious gaseous components from a flue gas, the flue gas is cooled, optionally subjected to preliminary purification, and optionally depleted of SO.sub.2. It is then heated in at least one heat exchanger and is passed over a catalyst suitable for the conversion of nitrogen oxides, whereupon the purified hot flue gas is conducted over at least one further heat exchanger and is discharged in the cooled state. Ammonia is preferably added to the heated flue gas.
