Advantages of ESP Collecting Electrodes :

  • Optimized & Uniform Current Profile
  • Capable to remove particle Size 0.01-10 microne and Clean Entire C.E Profile
  • Better Transmission of Rapping forces across
    the Width & Height of Collecting Plate
  • Good Strength and Rigidity.
  • Improved Collection Efficiency (99.9%)
  • C.E Plates to keep flow smoothly and no
    reentry of dust
  • Straightness and easy install both J Hooks and
    Bolting Systems.
  • Long – Term reliable operation at different
    Combination Fuel with High ASH Content.
  • Rigid & light for the collected dust to be easily
    rapped and removed.

Advantages of ESP Emitting Electrodes:

  • Smooth Surface Finish without Scaling.
  • Proper attachment of Hooks ensuring strong grip
    without causing any weakness of the D.E
  • Optimized / Maximum Secondary Voltage.
  • Effective Charging of particulate matter
  • Uniform Corona dicharge covering entire cross
    section.
  • Better Collection Efficiency.
