  • Publication number: 20150030509
    Abstract: An electrically heatable honeycomb body assembly includes an electrical connection of sheet metal layers at a connection pin. A honeycomb body has a metal casing with an inner periphery, through which the connection pin is led in a bushing and electrically insulated. The sheet metal layers are alternately coarsely structured and finely structured or smooth sheets together forming a stack with uppermost and lowermost layers and channels for an axial gas flow between the layers. The connection pin runs radially approximately perpendicular to the layers and is metallically connected to at least two or all of the layers through at least one intermediate piece. The uppermost sheet metal layer preferably runs approximately parallel to the metal casing over at least 35% of the inner periphery and is separated therefrom only by an air gap. Simple production of an operationally safe and very uniformly electrically heatable honeycomb body is provided.

    Abstract: An apparatus for treating a gas stream includes a plasma abatement device that has a reaction chamber and a plasma torch for generating a plasma stream for injection into the chamber for treating the gas stream. A first inlet conveys a gas stream into the plasma abatement device for treatment, and a second inlet, in a normal condition of the apparatus, is in flow communication with a source of reagent for conveying a reagent into the plasma device for improving the efficiency of the treatment. In a back-up condition of the apparatus, the second inlet is in flow communication with a gas stream source for conveying a gas stream into the device for treatment.

  • Publication number: 20140319117
    Abstract: A harness for electric heating catalyst (20) is connected to a catalyst case (12) housing a catalyst for purifying exhaust gas of an internal combustion engine and provided in an exhaust gas pipe (11) for exhausting the exhaust gas and includes a wire (50) connected to a power supply, and an electrode main body (70) for relay-connecting a case-side terminal (13) provided in the catalyst case (12) and the wire (50) and radiating heat transferred to the case-side terminal (13) from the heated catalyst. According to such a configuration, since the wire (50) is connected to the case-side terminal (13) of the catalyst case (12) via the electrode main body (70), heat transferred from the heated catalyst to the case-side terminal (13) is released into air at the electrode main body (70). Thus, damage to the wire (50) can be prevented by efficiently radiating the heat from the catalyst.

  • Publication number: 20140322090
    Abstract: A honeycomb body includes sheet metal layers forming a central current path to a radial connecting pin. A metal casing has an inner periphery and a feedthrough guiding and insulating the pin. The layers are alternate coarsely structured and finely structured or smooth sheets forming a stack with uppermost and lowermost layers forming axial gas channels. The pin is metallically connected to two or all of the layers directly or through an intermediate piece by an electrically conductive or welded connection. The current path has an electrical resistance per unit length in the connection region being greater than an average electrical resistance per unit length in the stack. The uppermost layer runs approximately parallel to the casing over 35% or 40% of the inner periphery and is separated from the casing by an air gap. Simple manufacture of a highly uniform, reliably operating, electrically heatable honeycomb body is thus possible.
