Abstract: DBW type electrostatic precipitators with three electric fields were used in the power plant of Huainan Xinji No.2 Mine. As the dedusting effect of the equipment was affected by the gas properties, there resulted in unstable emission and low dust-removing efficiency, which could not meet the requirement of the national new emission standards. Therefore, with the aim of meeting the demand for the Emission Standard of Air Pollutants for Thermal Power Plants (GB 13223-2011), the original infrastructure and equipment resource have been analyzed and calculated in this study; and the final solution was that the first original electric field was retained and the other two electric fields built later were reformed into low pressure pulse bag filters. The results shows that this transformation plan is realistic and feasible as the reformed system runs stably so far.
