Abstract
The use of a Calrod type electrical faceheater, powered by two 12V heavy duty batteries in series, as a regeneration initiator for a 12 in (30.5 cm) diameter × 12 in (30.5 cm) long segmented honeycomb ceramic filter is described. Recent test data, obtained on Deutz mining engines during the regeneration process, is presented. The effects of various regeneration parameters on the reliability and long-term durability of the filter is discussed together with the effect of fuel additives. The test data include both the measured temperature profiles and calculated thermal stresses in the filter with and without fuel additives.
