Removal of particulate matter from the emission gas of a small incinerator using a small-scale and uncomplicated electrostatic precipitator
Abstract:
Incineration is conceptually sound and as a waste treatment technology. There is, however,
concern over its air emission when it is improperly designed and operated. An electrostatic precipitator is
one of the most commonly used devices to control particulate emissions from boilers, incinerators and
some other industrial processes. To test this idea, a small-scale and uncomplicated electrostatic
precipitator for the removal of particulate matter from the exhaust gases of a small incinerator was
developed and investigated. The size of the precipitator was 1,000 mm (W), 1,000 mm (H), 1,000 mm (L)
and it was equipped with corona discharge wires. The corona discharge wires were connected to a
positive high-voltage pulse generator, while the collection plates were grounded. The high-voltage pulse
generator was used to produce the corona discharge field between the individual discharge wire and the
collection plate. The particulate-laden exhaust gas flow was directed across the corona discharge field.
The charged particles were deflected outward and collected on the collection plate wall. The precipitator
collection efficiency was evaluated as a mass loading ratio between the difference at the inlet and the
outlet, to the particulate loading at the inlet of the precipitator. The collection efficiency of this small-scale
and uncomplicated electrostatic precipitator design was found that approximately 80 %.
