A DENOX reactor including the associated flue gas channels is necessary in the chain of flue gas cleaning unit to denox the caloric large power station Heyden 4/Hanover. The medium shows 450°C temperature and is abrasive.
Heat-resistant steels (HII and 15Mo3) were used. The reactor has four DENOX-levels with HITACHI-catalysers; a folded structure was realized in the ground plan. The entire unit is isolated.
