| 摘 要： | 分析了2×600 MW机组所配套的两台双室五电场电除尘器(ESP)的设计、选型和改造。每台电除尘配套20台高压电源、一台炉配40台高压电源,改造工作不仅包括更换原80台单相电源为80台三相电源,而且将第一和第二电场的极板、极线及振打系统全部做了更换,改造后电除尘出口PM10和PM2.5(粒径分别低于10 μm和2.5 μm的颗粒物)的排放分别低于15 mg·Nm-3和1.0 mg·Nm-3,PM2.5占PM10的比例在6.5%~7.5%,与改造前比较PM2.5下降了95%以上。 |

| Abstract: | This paper discusses electrostatic precipitator (ESP) sizing，refitting and upgrading with 2×600 MW coal-fired boilers. Each boiler is equipped with two five-fields ESPs and 40 high-voltage (HV) power sources. Upgrading the HV power source refers to replacing the 80 single-phase HV sources by using 80 three-phase HV sources. Refitting ESP mainly includes changing both HV and collection electrodes and their rapping systems of the first and second electrical fields. PM10 and PM2.5 emission concentrations at ESP outlets drop below 15 mg·Nm-3 and 1.0 mg·Nm-3, respectively. The PM2.5 to PM10 ratio is around 6.5%~7.5%. In comparison with previous emission, PM2.5 concentration drops down by more than 95%. |
