VII CONFERENCE PAPER ABSTRACTS OU-1 SERIES
Held in Kyongju,
Conference on Electrostatic Precipitation (ICESP)
is the official conference of the International Society for Electrostatic
Rebuilding and Upgrading Electrostatic Precipitators – A
independent consultant can provide an objective assessment of the
users requirements, keeping in mind his clients preferences and
financial resources. Often
the existing EP can be rebuilt and upgraded at a fraction of the
cost of new equipment, and yet, efficiency can be increased
sufficiently to meet the emission limitations.
This paper presents an independent consultant’s perspective
on how an existing EP can be rebuilt and upgraded to improve its
efficiency and reliability, as an alternative to more costly
expansion of the existing casing or complete replacement.

Study on Design Parameters for Optimum Flow Distribution in
3-dimensional numerical simulation and experimental study were
conducted to study the design parameters, such as guide vanes,
perforated plates, and grids attached on perforated plates,
affecting flow distribution of the flue gas.
Numerical simulation was performed as a preliminary design.
Numerical simulation shows limitation in the design of EP
because of its complex geometry.
However, the flow pattern produced by the numerical
simulation can be used as important design information at the
initial stage of design. Experimental
study was conducted with a scale downed test model. The optimum
combination of the three major parameters, guide vanes, perforated
plates, and grids attached on perforated plates, was studied.
In addition, the techniques for the optimum combination were

second method permits to decrease the voltage drop across the dust
layer on the collection plates owing to pulse energization of the
conventional ESP sections. For
that purpose the pulse generator has the following parameters:

module. The comparison
demonstrated that the pulse microsecond energization could reduce
outlet dust leading by twice against the conventional energization.
