An assembly for treating gaseous emissions has a substrate along which extend cells for the passage of emissions gas. Lengths of conducting wire are located in a set of the cells and an induction heating coil is used to generate a varying electromagnetic field, so as to inductively heat the lengths of conducting wire. The substrate body has a front for entry of flowing emissions gas to be treated into the substrate body and a back for exit of treated gaseous emissions gas. The lengths of conducting wire have projections extending from the front and/or back of the substrate body so that when inductively heated, the wire parts in the substrate body heat the surrounding substrate and the wire projections heat the flowing emissions gas directly.
An assembly for treating gaseous emissions comprising a substrate body having a plurality of cells for the passage of emissions gas, respective lengths of conducting wire located in each of a first set of the plurality of cells, and an induction heating coil for generating a varying electromagnetic field, thereby to inductively heat the lengths of conducting wire, the substrate body having a front for entry of flowing gaseous emissions and a back for exit of treated gaseous emissions, at least some of the lengths of conducting wire having a part projecting from at least one of the front and back of the substrate body.
A method for treating emissions gas using a substrate body having a plurality of cells for the passage of the emissions gas, respective lengths of conducting wire located in each of a first set of the plurality of cells, the substrate body having a front for entry of the emissions gas into cells of a second set of the plurality of cells and a back for exit of treated emissions gas, at least some of the lengths of conducting wire having a respective part projecting from at least one of the front and back of the substrate body, the method comprising generating a varying electromagnetic field thereby to inductively heat the lengths of conducting wire, the heated conducting wire within the cells of the first set operating to heat the substrate body and thereby heat the emissions gas passing through cells of the second set, the heated projecting parts operating to directly heat adjacent emissions gas at at least one of upstream of the substrate body and downstream of the substrate body.
