Evaporator arrangement for generating a hydrocarbon/air or hydrocarbon/steam mixture that can be decomposed in a reformer for producing hydrogen and process for operating such an evaporator arrangement

摘要

An evaporator arrangement is provided for generating a hydrocarbon/air or/and hydrocarbon/steam mixture that can be decomposed in a reformer for producing hydrogen. A burner/evaporator area, which has a combustion/mixing chamber (14), into which air or/and steam enters via an inlet opening arrangement (16), a hydrocarbon-evaporating device (24, 34), including a porous evaporator medium (24) and, associated with same, a first heating device (34) and a glow type igniting member (28) for igniting a hydrocarbon-containing mixture present in the combustion/mixing chamber (14).
