| 中文摘要: |
| 通过宝钢电厂1、2号机组现役电除尘器高频电源和脉冲电源的工程设计、安装、调试和运行维护的实践阐述两种新型电源的供电特性以及对提高除尘效率的应用机理。实践结果显示，将高频电源运用在一、二、三电场，改造后排放质量浓度小于等于100 mg·Nm-3，将脉冲电源运用在四、五电场，改造后排放质量浓度在20 mg·Nm-3左右。高频电源适合处理高浓度中低比电阻粉尘，脉冲电源适合处理低浓度高比电阻粉尘。对于选择何种电源为佳，需要根据除尘器进口粉尘浓度以及不同工况条件下粉尘比电阻值来选择。 |

| Based on the experience of engineering designing, installation, tuning, operation and maintenance of in-service electrostatic precipitator with high frequency power supply and pulse power supply in the units 1 and 2 of the Baosteel power plant, the power supply characteristics and the mechanism for increasing dust removal efficiency by two new power supplies were introduced. The results of practice showed that the emission ≤ 100 mg·Nm-3 was achieved with the adoption of high frequency power supply in No.1, 2 and 3 electric fields while the emission was 20mg·Nm-3 with the application of pulse power supply to No.4 and 5 electric fields. High frequency power supply is suitable for removing the dust with high concentration and low resistivity while pulse power supply is suitable for the one with low concentration and high resistivity. The selection of power supply depends on the inlet dust concentration of electrostatic precipitator and its specific resistance under different working conditions. |
