Abstract

The present invention relates to a furnace superheater having a number of tube elements arranged relative to each other in such a way that they form a planar surface and in which the tube elements are mechanically arranged. The superheater elements are preferably rectangular of their cross-sectional profile and they are attached to each other by means of a groove or the like and a protrusion or the like which have a substantially similar profile. The present invention also relates to a circulating bed reactor provided with a furnace superheater.
