Modelling Investigation of the Thermal Treatment of Ash-Contaminated Particulate Filters

Abstract This paper investigates the impact of thermal treatment on pressure drop particulate filters containing ash deposits. A one-dimensional model has been developed and applied to describe deposition soot particles, estimate spatial distribution deposits in such filters. Phenomenological models have potential sintering cracking caused by filter. The results are good agreement with experimental measurements reduction thermally treated It was found that crack formation layer can lead significant at relatively low temperatures. Sintering wall plug also contributes towards a decrease filter higher work is first attempt order support development future management strategies. during identified be most critical effect for reduction.
