Abstract

An apparatus for regenerating depleted deNO.sup.d catalysts includes a combustion chamber having a combustion zone, a flue gas conduit communicating with the combustion zone and a deNO.sub.x catalyst having surfaces in the flue gas conduit. An injection device may be disposed between the combustion zone and the surfaces for injecting molybdenum-oxide-containing dust when the deNO.sub.x catalyst is depleted, or a molybdenum-oxide-containing surface may be disposed in the flue gas conduit between the combustion zone and the surfaces for regeneration when the deNO.sub.x catalyst is depleted.
