Evaporator arrangement for generating a hydrocarbon vapor/mixed material mixture, especially for a reformer arrangement of a fuel cell system

摘要

An evaporator arrangement and/or vaporizing burner is provided for generating a hydrocarbon vapor/mixed material mixture. The arrangement has a mixing chamber ( 50 ) surrounded by a circumferential wall area ( 46 ) and a bottom wall area ( 44 ). Inlet openings ( 48 ) are provided in the circumferential wall area ( 46 ) for the entry of gaseous mixed material into the mixing chamber ( 50 ) and the bottom wall area ( 44 ) has a porous evaporator medium ( 62 ) for absorbing liquid hydrocarbon. A first heating device ( 76 ) is associated with the porous evaporator medium ( 62 ). A second heating device ( 94 ) heats the mixed material before or/and during its passage through the inlet openings ( 48 ).
