Many options exist for monitoring various types of dust emissions including nuisance emissions, ambient/fugitive dust levels or emissions from a pollution control device such as an air scrubber or fabric filter dust collector.
With ever more stringent regulations and the need for high performance from industrial processes in order to compete in a global marketplace, many facilities can no longer afford to install, operate and/or maintain outdated systems. The need for the best cannot be overlooked when considering operational and compliance issues for your facility.
3 Reasons Why Accuracy Matters
Accuracy matters because accurate dust collection monitoring provides operators with the needed insight to operate, optimize and maintain these systems. Trying to operate a dust collector without accurate dust emissions data is like flying an airplane without an altimeter or driving a race car without a tachometer. Lack of data means poorer decision making and degraded performance.Read More
Invention born of a mishap
Often we discuss the advantages of triboelectric dust monitoring technology over other particulate emissions monitoring methods for plants covered under MACT standards. For the most part, the majority of these advantages come from the much greater detection range and sensitivity of triboelectric technology. Triboelectric detectors can register changes in dust concentration down to 0.000002 g/dscf or 0.005 mg/m3. The next most sensitive detection device (opacity meters and other optical based monitors) can only reach down to 5 -10% opacity, which in most applications equates to about 10 - 20 times less sensitive. Even so, many industries continue to use opacity based systems despite this and other shortcomings of opacity monitoring solutions compared to triboelectric technology.Read More
From Opacity Hassles to Operational Value
With such a disjointed set of strategies and devices used for environmental compliance today many wonder how things ended up like this. Let's explore the history of environmental compliance monitoring technologies and see how we ended up where we are today.
And then, given today's capabilities, explore how some companies turn the traditional regulatory headache into an opportunity for legitimate operational value creation.
Early Days - Visual ObservationsRead More
For many, differential pressure has been the only operation data they have ever monitored on their dust collection system. For decades, DP has been the go to for monitoring performance, used as an indicator of total emissions and for diagnosing maintenance issues. Even though monitoring technology has advanced significantly since the 1970s when these regulations were first put forth, many plants continue operating under their older requirements. "That's what we've always done," and "That's what my permit calls for us to do," usually lead the way. Even today where superior monitoring methods are available, it is common to find plants that feel there is no need to monitor anything more than their DP to achieve compliance.Read More
Planning for recirculating from a dust collector
NFPA 654 Standard for the Prevention of Fire and Dust Explosions from the Manufacturing, Processing and Handling of Combustible Particulate Solids provides general guidelines for combustible dust control in industry. The NFPA also has two standards that cover specific guidelines for explosion protection systems (NFPA 68) and explosion prevention systems (NFPA 69). There are also three other standards for specific industries that require slightly different (usually stricter) regulation. These include NFPA 61 that concerns agricultural facilities, NFPA 484 covering combustible metals and NFPA 664 covering woodworking facilities.Read More
One of the major factors that many engineers or company decision-makers often forget about compliance is how air quality control technology can also bring financial benefits to facilities, most often in the form of reduced labor, material savings and risk prevention.Read More
Air material separators - critical for dust collection and recirculation
Despite the well know dangers associated with combustible dust hazards there exist few specific OSHA/MSHA regulations covering them outside of a handful of specific industries (e.g. grain elevators) on a national level. Rather, local jurisdictions normally base their regulations on the guidelines found in the National Fire Protection Agency standards that outline best practice for eliminating or controlling these hazards.
The most widely used NFPA standard for combustible dust is NFPA 654 - Standard for the Prevention of Fire and Dust Explosions from the Manufacturing, Processing, and Handling of Combustible Particulate Solids. This standard contains guidance that is applicable to most combustible dusts in general industry and is attracting new attention based on updates to the regulations around recirculating air from dust collectors and combustible dust monitoring.Read More
Doing More With Less
Its rare for baghouse maintenance budgets to see any kind of increase each year. Usually, maintenance planners, managers and technicians must do more with even less each year. With this in mind we've pulled together a list of steps your plant might explore to reduce dust collector maintenance costs. Most require a minimal capital investment but quickly provide returns in the form of less man hours, lower operating costs and increased reliability - in other words not just lower costs, but delivering big, measurable operational benefits.

Cement is a building block industry of global progress. Roads, buildings, bridges, factories, stadiums, airports and more - everywhere we go, and everything we do is built on cement. And because it’s everywhere many take it for granted….but not all of us
In fact, we’re focused on the cement industry and Auburn’s triboelectric detection devices are used for many different functions in cement plants around the world.Read More
