【Abstract】 A new regeneration technique using infrared heating technique for honeycomb ceramic filter was developed successfully. The infrared regenerating mechanism and the selective heating feature were analyzed. The infrared heater for the regeneration was presented. The characteristics of infrared regeneration were investigated on the 6110A diesel engine bench. The experimental results show that infrared regeneration has high regeneration efficiency at more than 90%, little difference among the maximum temperatures at any position of honeycomb ceramic filter, the maximum temperatures at 8001 000 , lower temperature gradient at less than 10 /cm. The infrared heating technique suits the heating regeneration qualification of honeycomb ceramic filter. The maximum temperature and the regeneration time are affected notably by infrared electric power and the exhaust flow rate, and infrared regenerating technique is controllable.更多还原
