Thermal regeneration of diesel‐particulate monolithic filters

Abstract

Abstract A mathematical model is developed to describe the process of thermal regeneration in diesel‐particulate monolithic filters. The model shows that a typical regeneration cycle consists of four stages: preheating, ignition, transport‐controlled combustion, and cooling. The total regeneration time and the peak temperature are the important regeneration characteristics and can be controlled by initial particulate loading, total filtration area, and channel wall thickness.
