An ammonia oxidation catalyst basket design has two support grids. A first grid supports the primary catalyst and a separate, second grid supports the secondary catalyst. This dual grid design separates the two catalysts, and enables the catalysts to be independent of each other. Any interruption in the primary or the secondary catalyst does not impede or adversely impact on the structure or function of the other catalyst.

Catalyst support systems for ammonia oxidation burners comprising a top flange and an inner wall. The top flange comprises a planar section, a rounded outer edge, and a rounded inner edge, the rounded outer edge and the rounded inner edge being separated by the planar section. The inner wall comprises a carrier plate, a gauze shelf, and a bottom plate shelf, the gauze shelf and the bottom plate shelf being attached to the carrier plate. The carrier plate is attached to the top flange by means of the rounded inner edge.
