A vessel for producing SO3 from SO2-containing gas includes a plate-like element and a bracket disposed on a wall of the vessel. The bracket is configured to support the plate-like element by a supporting surface. The supporting surface is an upper supporting surface curved downward away from the plate-like element in an unloaded state of the vessel or a lower supporting surface curved upward away from the plate-like element in the unloaded state of the vessel.
