The Application Practices of the Double-zone ESP in Coal-fired Power Plant

摘要：

Through intensifying respectively functions of the charge zone and the dust collection zone of the electric fields,double-zone ESP is able to avoid back corona and to collect dust negatively charged and dust positively charged at the same time consequently to increase dust removal efficiency. Through the application effects of the mating four sets of double-zone ESPs and 4 sets of traditional horizontal type ESPs for the 4×300 MW unit in some power plant, it is proven that the double-zone ESP possesses higher dust removal efficiency and is able to increase dust migration velocity and to save floor space, steel consumption and power consumption, as compared with the conventional ESP.
