Electrostatic
precipitators (ESP) are widely used around the world in many different
processes to clean exhaust gases e.g. from combustion- and mineral refining
processes.
It is also
very common, that during the years the existing processes are further developed
to increase production capacities, etc. resulting in notable changes in process
parameters. These changes typically result in deterioration of efficiency
meaning higher dust emissions. In such case it would be good to realize, that
existing air-pollution control equipment can typically be upgraded with small
changes and/or modernizations which are pricewise and timewise more economical
than constructing completely new equipment.
Preciptek
Oy’s personnel has over 33 years of experience developing, planning, performing
and consulting of such ESP upgrades around the world.
A properly
designed and constructed Electrostatic Precipitator (ESP) has a lifespan of
several decades. The operation of an ESP is based on a high voltage electricity,
fixed electrodes and low flue gas velocity, so the number of moving parts, wear
and other maintenance needs are already low from a structural point of view.
Deviations from
optimal circumstances do occur and may cause abnormal wear or corrosion in the
ESP parts and structures. Because of this, a mechanical inspection should be
carried out periodically inside the precipitator. The inspection includes a
complete evaluation of actual wear parts and corrosion as well as parts
susceptible to fatigue.
PRECIPTEK’s
MECHANICAL INSPECTION SERVICE is carried out during maintenance shut down by an
expert, who is specialized in working safely in the demanding environment of ESPs.
