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 18):
A gas duct comprising:\n a duct wall with an interior space enclosed by the duct wall, the duct wall comprising a metal material, a duct wall inner surface and a duct wall outer surface; a heated porous metal structure arranged in the interior space of the gas duct for passing through gas; at least one electric heater, heating the porous metal structure, wherein the electric heater is a mineral-insulated heater with a heat conductor, with one or more front-side connection openings and with at least one outer metal jacket, wherein the electric heater has at least one section which passes through the duct wall so all of the one or more front-side connection openings are arranged outside the interior space of the gas duct and the outer metal jacket of the electric heater is welded or soldered in the at least one section to the duct wall, and wherein the heat conductor is completely embedded in a compacted ceramic insulation at least in interior sections of the electric heater that are arranged in the interior space of the gas duct, the at least one outer metal jacket comprising an outer metal jacket surface, the outer metal jacket surface extending from a position located radially outward of the duct wall outer surface to a position located radially inward of the duct wall inner surface with respect to a longitudinal axis of the duct wall.
