Abstract
A heating device for filter elements of a soot filter, as well as a soot filter are described. The filter elements are disk-shaped and stacked on one another in said soot filter. The heating device has a tubular heater with an outer tube and a heating conductor located therein. The essence of the invention is a very small diameter of the tubular heater compared with conventional tubular heaters. It is also constructed in such a way that its path covers a certain area. This can e.g. be a quadrant or semicircle in a round filter element. The arrangement of the tubular heater in the soot filter is such that it passes close to the filter surface of the filter elements.
