이300 MW과로전제진기위례，통과전제진시험분석，조정도류판화기류분포판，우화제진기각실류량편차급기류분포，사기류분포상대균방근차치소우0．025，제고제진기효솔0．06％；통과전제진기내부우화、고빈전원기술적응용，진일보장연진배방농도유43 mg／m3강지20 mg／m3이하，동시제출강화전엄제진효과적기술조시。
Taking 300 MW power boiler electrostatic precipitator for example, the airflow distribution test was con-ducted, the guide plates and uniformity al ocation plates were adjusted, the deviation of rate of flow and the uni-formity of different room were optimized.The relative mean variance was reduced below 0.025, and the efficien-cy was raised 0.06%.And the other optimization technologies like internal optimized and high frequency power technology were applied, which reduced the dust concentration from 43 mg/m3 below 20 mg/m3 .The measure of enhance dedusting effect was also introduced.
