Steam superheaters

Our steam superheaters can be used for steam pressures up to 130bar (13,000 kPa) and steam temperatures up to 530°C.

They are arranged direct in line after the waste heat boilers which are connected to the secondary reformer or reformer – depending on the process.

The steam superheater can be provided as two stage or one stage, horizontally or vertically arranged. The final design arrangement is determined by the process requirements. 

The process steam superheater is usually vertically arranged with U-tubes and a combined steam inlet/outlet chamber. The reformed gas flows on the shell side in a guiding jacket in counterflow to the steam on tube side. 

In order to prevent heat transfer from the hot to the already cooled gas, the separating and guiding jackets used for flow guidance are thermally insulated.

A refractory lining of the entire shell is not necessary due to the low gas outlet temperature. Only in the area of the bypass is a refactory lining installed for safety reasons.
