Catalyst module with catalyst elements

The invention relates to a catalyst module (1) with internal fittings made of catalyst elements (2), wherein the surface area of the individual catalyst elements, against which flow is directed, is greater than the flow entry surface area of the catalyst module, wherein the surface of the module side facing the main direction of flow (S) is defined as the module entry surface, and wherein the catalyst elements in the catalyst module are positioned such that flue gas flows through said elements in a direction differing from the entry side and/or the exit side direction of flow.
