PCT No. PCT/EP96/04045 Sec. 371 Date May 15, 1998 Sec. 102(e) Date May 15, 1998 PCT Filed Sep. 14, 1998 PCT Pub. No. WO97/11330 PCT Pub. Date Mar. 27, 1997Described is a heat exchanger comprising a nest of heat-exchange tubes held between two end plates, the heat exchanger being designed for connection downstream of a thermal-cracking installation. In order to reduce erosion of the base plate, the plate at the input end is coated on the side facing the oncoming gas with an erosion-resistant, fireproof coating of a chemically bound compound, leaving clear the apertures for the heat-exchange tubes.
