Bearing arrangement for a reformer tube

15:

• The reformer tube according to claim 14, wherein the reactant feed line has only one single change of direction.

16:

• The reformer tube according to claim 14, wherein the product discharge line has no change of direction and the longitudinal axis coincides with or is aligned with the longitudinal axis of the pressure-bearing cylindrical jacket tube.

17:

• The reformer tube according to claim 14, wherein the floating bearing is designed as a rolling bearing, ball bearing, plain bearing, or floating support bearing.

18:

• The reformer tube according to claim 14, wherein the floating bearing and the fixed bearing are designed such that they can absorb stress forces due to thermal expansion of the pressure-bearing cylindrical jacket tube in the radial direction.

19:

• The reformer tube according to claim 14, wherein the inlet ends of several jacket tubes can be connected to a common reactant feed line.

20:

• The reformer tube according to claim 14, wherein the product discharge line forms a right angle with the product gas manifold in the connected state.

21:

• A reformer furnace comprising a floor, a ceiling, and side walls forming a furnace interior, wherein a plurality of reformer tubes according to claim 14 are arranged within the furnace interior and are heated by burners.

22:

• The reformer furnace according to claim 21, wherein the plurality of reformer tubes are arranged in rows, wherein each two reformer tubes adjacent in a row are connected to a common reactant feed line.
