600MW机组除尘器升级改造及效益评价

Discussion on ESP reformation of 660 MW units and its benefit evaluation

元宝山发电有限责任公司2号600 MW机组配套电除尘器由于设计效率低、燃烧煤种变化、设备老化等多方面原因,除尘效率下降,除尘器出口烟尘排放浓度超标严重。为了满足新的《火电厂大气污染物排放标准》的要求,对元宝山发电有限责任公司2号机组配套电除尘器进行升级改造,将原有的4台四电场静电除尘器增效改造为4台电袋复合式除尘器。通过电除尘器的改造,降低了除尘器出口粉尘排放浓度,提高了除尘效率,保证了2号机组电除尘器的安全稳定运行.

Yuanbaoshan Power Limited Company No. 2 boiler 600 MW units ESP due to the low design efficiency of ESP,burning coal change,aging equipment,and many other reasons,the dust efficiency decreased. The precipitator dust emission concentration exceeded the standard request seriously. In order to meet the new Thermal Power Plant Air Pollutant Emission Standards＇ s requirement,the ESP is reformatted,the original four four- field ESP are reformatted to four electric field electrostatic precipitator. Through the transformation of ESP,the dust emission concentration of ESP is reduced,ESP＇s,the dust- removal efficiency is improved,and the safe and stable operation of ESP is ensured.
