Oven with electric and fuel-heated reactor tubes for steam reforming of a hydrocarbon-containing insert

摘要

The invention relates to a furnace for steam reforming of a hydrocarbon-containing, preferably methane, feed stream (E) comprising: a combustion chamber (10), a plurality of in the combustion chamber (10) arranged reactor tubes (20) for receiving a catalyst (K) and for carrying out the Feed stream (E) through the reactor tubes (20), at least one burner (30) which is adapted to burn a fuel in the combustion chamber (10) for heating the reactor tubes (20). According to the invention, in addition to the at least one burner (30), at least one voltage source (2) is provided which is connected to the plurality of reactor tubes (20) in such a way that in each case an electric current can be generated in the reactor tubes (20). 20) for heating the insert (E) is heated.
