Abstract：In order to improve the life and reliability of moving-electrode type electrostatic precipitator(MEEP) for efficiently capture the PM2.5 dust in flue gas,this article studied the wear,fatigue and service life of MEEP's drive chain under simulated operating conditions on a home-made chain test-bed furnace.The related factors affecting the furnace performance were systematically investigated by the aspects of temperature,dust environment,load force,working hours etc.The experimental results show that the inner surface of sub-roller,the outer surface of sleeve and pin are found undergo significant wear,and they are mainly caused by abrasive wear and accompanied by fatigue wear.In addition,the test chain can meet the designing requirements for eight years under operating condition criteria,and the elongation of chain can be less than 1％.
