ABSTRACT:
The tubular heater comprises numerous tubes, which are disposed in a combustion chamber and contain catalyst. A synthesis gas, which mainly comprises hydrogen, carbon monoxide, and carbon dioxide, is prepared in the tubes. There is a risk of a formation of carbides (metal dusting corrosion) on the outside surface of the outlet ends of the tubes. To prevent such corrosion, a gaseous or vaporous protecting fluid, which is substantially free of CO, is supplied to the region surrounding the outlet ends of the tubes.
