Abstract:
A gas duct ( 100 ) has a duct wall ( 110 ) enclosing an interior space ( 120 ), a heated porous metal structure ( 113 ) arranged in the interior space ( 120 ) for passing through gases and an electric heater ( 102 ). The electric heater ( 102 ) is a mineral-insulated heater including a heat conductor ( 104 ), one or more front-side connection openings and an outer metal jacket ( 108 ). The electric heater ( 102 ) has a section ( 102 a ), which is passed through the duct wall ( 110 ), so that all front-side connection openings ( 116 ) are arranged outside the interior space ( 120 ) of the gas duct ( 100 ) and the outer metal jacket ( 108 ) is welded or soldered to the duct wall ( 110 ) in the section. The heat conductor ( 104 ) is completely embedded in a ceramic insulation ( 106 ) at least in the sections of the electric heater ( 102 ) that are arranged in the interior space ( 120 ) of the gas duct ( 100 ).

Claim (Index 11):
The gas duct in accordance with  claim 1 , further comprising at least one further electric heater, heating the porous metal structure, wherein the further electric heater is a mineral-insulated heater with a further heat conductor, with one or more further front-side connection openings and with at least one further outer metal jacket, wherein the further electric heater has at least one further section which passes through the duct wall so all of the one or more further front-side connection openings are arranged outside the interior space of the gas duct and the further outer metal jacket of the further electric heater is welded or soldered in this further section to the duct wall, and wherein the further heat conductor is completely embedded in a further compacted ceramic insulation at least in interior sections of the further electric heater that are arranged in the interior space of the gas duct the at least one electric heater and the at least one further electric heater comprise a plurality of mineral-insulated heaters arranged in the porous metal structure.
