Claim 0:
1. A reformer furnace for use in converting a hydrocarbon feed into a synthesis gas stream, said reformer furnace having an enclosed volume defined by opposing first and second endwalls and at least one sidewall extending between said first and second endwalls;
said reformer furnace comprising at least one bayonet reformer tube located at least partly within said enclosed volume,
said at least one reformer tube comprising an first end portion and a second end portion, arranged at opposite ends of said at least one bayonet reformer tube along the length axis Y-Y thereof;
wherein a feed gas inlet for said hydrocarbon feed and a process gas outlet for said synthesis gas stream are arranged in said first end portion of said at least one bayonet reformer tube;
wherein said second end portion of the at least one bayonet reformer tube is closed;
wherein said reformer furnace further comprising a first support arranged to support the second end portion of said at least one bayonet reformer tube against the second endwall of the reformer furnace to prevent the second end portion of the bayonet reformer tube from being displaced in a direction perpendicular to said central axis Y-Y relative to the reformer furnace;
wherein the bayonet reformer tube extends along a central axis Y-Y and said first support is arranged to permit the second end portion of the bayonet reformer tube to be displaced during operation in a direction parallel to said central axis Y-Y relative to the reformer furnace;
