Particulate Emission Monitoring
Solutions
for the Cement Industry
Coal Mills
Coal Mill bag filters employing ElectroDynamic™ Probe Electrification systems can be
monitored not only for legislative performance compliance but by
utilising PCME’s unique Predict software package, the monitor may also
be used as a powerful filter maintenance tool. For areas designated as
Hazardous Zones ATEX approved instruments can be provided. [top]
Cement Mills
The moist stack conditions normally associated with Cement Mills
prevents the reliable use of traditional dust monitoring techniques.
The use of PCME’s patented Fully Insulated ElectroDynamic™ Probe Electrification Sensors
overcomes the problems associated with sensor contamination and
electrical short circuiting experienced by both Optical and
Triboelectric techniques. [top]
Quarrying
Filters used on crushing and milling applications normally emit very
low levels of dust, typically single figure mg/m3. To monitor
these low levels of emissions in relatively small diameter stacks PCME
employ ElectroDynamic™ Probe Electrification
instruments. [top]
These systems are
virtually maintenance free, requiring no additional services such as
air purging making their cost of ownership extremely low compared to
other monitoring techniques.
Kiln
Monitoring
The choice of monitoring technique for main Kiln stacks is dependant on
both the Filter type (Electro-filter/Bag House) and local legislative
requirements.
Optical technologies
including DynamicOpacity™
Ratiometric Opacity and EN14181 compliant ProScatter™ Forward
Scatter instruments are best suited for monitoring Electro-filters,
their advance operating techniques providing both accurate dust
measurement and greatly reduced maintenance requirements compared to
traditional optically based systems.
The lower particulate emissions from modern Bag Houses may be
successfully monitored utilising ElectroDynamic™ Probe Electrification systems
(EN14181 compliant). Unlike optical systems this technique
requires no additional services (air purge) being unaffected by dust
build-up on the sensor rod. [top]
Silo Filters
Filters employed to prevent large scale emissions from storage silos
can be monitored by either single sensors or multi-channel networked
systems.
These instruments feature
on board logging to assist the setting of alarm levels to warn of
filter leakage or rupture to avoid product loss and environmental
impact. [top]
Filter
Management Systems
Each compartment of a multi-chamber Bag House can be monitored in
real-time by a series of networked ElectroDynamic™ Probe Electrification sensors.
This allows the pinpointing of leaking filters before environmental
limits are breached.
The use of such Filter
Management Systems has a proven track record of not only lowering total
emissions but also reducing maintenance times/costs together with the
possibility to increase production throughput.
Additionally ElectroDynamic™ Probe Electrification units may
be employed pre-filter on both Bag House and Electro-filter
applications in conjunction with an environmental monitor to ascertain
filter performance. [top]
