Abstract (en)
[origin: EP2256411A2] The pipe has a flow channel provided with a channel wall and a channel interior part (5), and a particle rejecting unit (9) implemented as a thermally induced moving element (9a). The moving element is deformed when temperature is changed, and is formed as an integral section of the pipe or a separate unit in or at the pipe. The moving element is designed as a snatching element (11) and arranged at the channel wall, where the moving element is thermally induced when threshold temperature is exceeded. An independent claim is also included for an electrostatic precipitator for an exhaust gas purification system.
