  • Method for cleaning a particle filter
    Patent number: 7625433
    Abstract: The invention relates to a method for cleaning a particle filter (1) with the following method steps: a gaseous stream laden with pollutants and/or particles is fed to a particle filter (1) that operates catalytically and/or by filtration, pollutants and/or particles are chemically converted or stored in the particle filter (1), filtrate or ash particles (2) being produced and/or deposited on the particle filter (1). Once the particle filter (1) has been used for a specific period of time, a layer (3, 4) for increasing the through-flow resistance is applied to the layer of filtrate or ash particles (2) in the direction of filtration.
