Exhaust system for a steam reformer and bearing therefor

An exhaust system for a steam reformer, comprising:

• a hot exhaust system comprising at least one longitudinal collecting tube;
• catalyst tubes aligned parallel to each other and orthogonally to the longitudinal collecting tube;
• a plurality of ports disposed along the longitudinal axis of a first side of the longitudinal collecting tube, wherein each port is configured to connect to a respective catalyst tube, wherein the ports are arranged such that in the connected condition, the catalyst tubes are aligned parallel to each other and orthogonally to the longitudinal collecting tube;
• a cold exhaust system comprising a transverse collector which is fluidly connected to a second side of the at least one longitudinal collecting tube and has a longitudinal axis which extends orthogonally to the at least one longitudinal collecting tube and orthogonally to the catalyst tubes,
• wherein the second side of the longitudinal collecting tube is opposite of the first side the longitudinal collecting tube, wherein the transverse collector is disposed centrally to the longitudinal collecting tube.
