Abstract (en)

[origin: WO2004104387A1] The invention relates to a method for cleaning a particle filter (1), comprising the following steps: a gaseous stream charged with pollutants and/or particles is fed to a particle filter (1) that operates catalytically and/or by filtration; the pollutants and/or particles are chemically converted or stored in the particle filter (1), whereby filtrate or ash particles (2) are produced and/or are deposited on the particle filter (1). Once the particle filter (1) has been used for a specific period of time, a layer (3,4) is applied to the filtrate or ash particle layer (2) in the filtration direction to increase the flow resistance.
