VII CONFERENCE PAPER ABSTRACTS DE-3 SERIES
Held in Kyongju,
Conference on Electrostatic Precipitation (ICESP)
is the official conference of the International Society for Electrostatic
Current Distribution and Re-entrainment of Low Cohesive Dust
the geometry lies the demand for a proper current distribution on
the collector plate, i.e. the ideal is supposed to be an even
current distribution, particularly important if the dust layer on
the plate is high resistive.
also in cases of low resistivity and a loosely compressed or a low
cohesive dust layer an insufficient current distribution may cause
problems with low precipitator efficiency due to re-entrainment from
low current density regions. The
present paper reports a case story describing a non-optimal
combination of discharge electrode geometry, low resistive fluffy
dust, and average current density.
It is attempted to explain the physics involved based upon
results from high resistive operation and upon the importance of the
secondary flow induced by the ion wind.
though very efficient rapping removes some of the causes of
re-entrainment of fluffy dust, because the dust layer is kept very
thin, it will be demonstrated that a well designed electrode
geometry may prevent perceptible re-entrainment to arise at all.
