Abstract

This paper discusses the optimization of 16 high-voltage power sources for the four-field electrostatic precipitator to achieve energy saving and fly ash emission reduction. With 16 traditional single-phase rectifier-transformers (T/Rs), the PM₁₀ and PM_2.5 emissions and the primary power consumption are about 63 mg/m³, 23.9 mg/m³ and 1225 kV·A, respectively. After retrofitting the power sources with 16 ZH type three-phase T/Rs, the PM₁₀ and PM_2.5 emissions and the primary power consumption are about 10-16 mg/m³, 2.0-2.5 mg/m³ and 900-1050 kV·A, respectively. For a similar primary energy consumption, emissions for PM₁₀ and PM_2.5 are reduced by about 78% and 92%, respectively.
