Abstract (en)

[origin: US2004020193A1] The invention relates to a method of cleaning a particle filter (1) by means of a fluid, whereby the filter material is alternately treated with pressure and high flow rate. By means of the above method, the ash is washed out of the filter material, essentially more effectively, namely quicker and more completely and more gently for the filter material (2) than previously possible.
