(DE19721630-C1)      Apparatus for reforming educts containing hydrocarbons comprises a radiation burner and a reforming reactor containing partially catalyst-coated metal honeycomb bodies. The radiation burner (b) encloses the reforming reactor (c, d) made of two parts, the reactor heated by radiation and convection. The combustion gas and educt gas are fed between both reforming reactor parts (c) and (d).    Preferably part (c) is formed as a ring slot reactor, and part (d) as a tubular reactor. A heat exchanger (w) is arranged above the reforming reactor (c, d), through which the educts and combustion gas are passed. The heat exchanger (w) has a tubular helix (e) to introduce the educt and the combustion gas is fed through concentric tubes (f) to the combustion gas outlet (4). The burner (b) consists of ceramic orifice plates and is divided into several segments.    USE -   Used for industrial and small-scale plants, eg. for hydrogen production from fossil fuels, operating using a steam reforming process. The hydrogen-rich synthesis gas is then used to produce NH3, alcohol or methanol. Highly pure hydrogen produced can be used in fuel cells.    ADVANTAGE -   The apparatus produces low heat losses.
