                    Abstract:Deep peak regulation transform of coal-fired units is the mainstream means to improve the consumption
                    of  new  energy  under  the  dual-carbon  target.  The  dust  removal  efficiency,power  consumption  and  economy  of


                    Electric Precipitator (ESP)under deep peak regulation is compared and analyzed. It is found that the electric pre‑
                    cipitator  has  a  large  space  for  energy  saving.  A  closed-channel  ESP  suitable  for  19%  ultra-low  load  deep  peak
                    regulation is proposed. Taking the million-kilowatt unit as an example,the comparison is made with the isolation

                    and vibration ESP technology of Mitsubishi Heavy Industries of Japan. The comparison results show that the total
                    cost of closed-channel type electrostatic precipitator in the lower pass is only 83.3%,79.4% and 75.5% of con‑

                    ventional ESP with the design life of 10 years,20 years and 30 years respectively,and the energy saving effect is


                    obvious.
