A furnace for steam reforming a feed stream containing hydrocarbon, preferably methane, having: a combustion chamber, a plurality of reactor tubes arranged in the combustion chamber for accommodating a catalyst and for passing the feed stream through the reactor tubes, and at least one burner which is configured to burn a combustion fuel in the combustion chamber to heat the reactor tubes. In addition at least one voltage source is provided which is connected to the plurality of reactor tubes in such a manner that in each case an electric current which heats the reactor tubes to heat the feedstock is generable in the reactor tubes.

The invention relates to a device for the reactive conversion of gaseous streams at high temperatures in excess of 1000&#xb0; C. Said device comprises a reaction chamber () with an inlet opening for the gaseous streams to be converted, in particular a burner head () and an outlet opening for the converted gaseous streams. In order to guarantee the highest possible conversion performance, the reaction chamber () has a narrow construction, extending longitudinally from the inlet opening to the outlet opening to form a controlled gaseous flow, thus preventing a circulatory flow in the reaction chamber (). To achieve reaction conditions that are as adiabatic as possible, the reaction chamber () is thermally insulated with a layer () that has a porous foam and/or fiber structure. In the simplest embodiment, the reaction chamber () is cylindrical, thus achieving a tubular flow reactor construction for the entire device.

The invention relates to a process and an apparatus for producing a profiled sheet, in which the sheet is provided with a corrugation which runs obliquely with respect to the edges of the sheet and has a substantially constant angle of inclination. At least one edge region of the sheet is deformed by means of a ram-like deformation tool () which is alternately brought into contact with the edge region and removed from the edge region.
