What's the Most Accurate Method to Monitor Dust emissions?

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in order to compete in a global marketplace, many facilities can no longer afford to install, operate and/or maintain outdated systems.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.

Do I Have to Monitor Stack Emissions From My Industrial Dust Collector?

Air Permit Compliance is Confusing

Often facilities have a difficult time identifying exactly what local, state and federal regulators require of them regarding their dust collection systems. This is not unreasonable as the myriad of overlapping environmental, and health and safety requirements that affect dust collection systems can be quite the twisted knot to untangle. And stack monitoring requirements are just one more confusing twist in the knot. Many wonder if these monitoring requirements apply to them since their dust collection system is relatively simple and small scale.

Methods for Measuring PM Emissions and Fabric Filter Performance Part 2

As we considered in our article Different Methods for Measuring PM Emissions and Filter Performance, plants face a difficult task comparing data derived from various methods of measuring PM emissions. Often  fabric filter manufacturers, dust collection system OEMs and other product manufacturers use units that are different than those used by regulatory authorities for emissions standards and for specific requirements of air permits.  

In the last article we considered methodologies used by control equipment manufacturers and their purpose such as grains per standard dry cubic foot, or parts per million. Now we will consider those used by regulatory agencies, their reasons for doing so, and how we can convert back and forth between them when needed.

Triboelectric Detection for Early Warning of Hopper Bridging in a Cyclone Dust Collector

Cyclone Dust Collector Bridging & Other Hassles

Triboelectric dust detection systems can be used effectively to monitor a cyclone dust collector just as well as a fabric filter collector. In the same way that triboelectric systems can monitor baghouses for collection efficiency, operational output and maintenance needs, so to can they monitor cyclone dust collectors. In this article we'll take a quick look at common applications for cyclone collectors and then dig into two common operating problems that triboelectric detectors can assist with.

Triboelectric Dust Detection Tech Basics - 3 Articles to Read First

Lots of information, but where to start?

As of Dec '16 we've published more than 75 articles on triboelectric dust detection technology and particulate emissions monitoring. They cover technical details, tips on use, suggestions to reduce downtime and operating cost and even how our technology is increasingly finding application in process industries for monitoring and control bulk dry goods conveying. 

We're committed to building this body of knowledge for emissions monitoring and process control experts worldwide. But with so much information, we know that sometimes folks new to the discipline may not know exactly where to start. So instead of boiling the ocean, here are three basic articles that we recommend reading first.

  1. Triboelectric Dust Detection vs. Opacity Meters - Is there a difference?
  2. Triboelectric instrumentation for process improvement
  3. AC vs. DC - The role of signal Spectrum in triboelectric monitoring

Triboelectric Ambient Fugitive Dust Monitoring — How It Works

Invisible (or barely visible) threats

When we talk about dust emissions, particulate emissions or PM 2.5/PM 10 we are usually referring to emissions that go outside from a dust collector outlet or a stack. Since these are usually the focus of any regulatory or process concerns it is usually what we default to when talking about dust issues.

Triboelectric Monitoring Systems and the Cement Industry

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.

Should I Calibrate My Triboelectric Bag Leak Detection System?

Who needs one more PM task....

Many wonder if their triboelectric bag leak detection system needs any kind of calibration to function properly. That's entirely understandable since many are accustomed to working with opacity meters or other older generations of equipment. Opacity meters require an initial calibration along with periodic calibration and rebuilds at specified intervals in order to stay accurate. 

While many OEMs can quickly state that “triboelectric systems do not need calibration” it can be confusing when some incorrectly refer to certain actions as “calibrating” their triboelectric unit.

So what is the truth, do you need to calibrate your triboelectric detector? 

Current generation Triboelectric Bag Leak Detection Systems Do Not Require Periodic or Initial Calibration

The Battle Between Triboelectic Dust Detection and Opacity Meters

Regulating authorities require nearly all industrial facilities to measure dust particulate emissions in some fashion. Opacity meters were, for decades, the standard required by the EPA and under many State and Local air permits.

However, in recent years, triboelectric particulate monitors have been promoted by some as superior to opacity meters, and have begun replacing opacity meters in many applications across all industries. So why the change? Is there a reason to switch to triboelectric monitoring devices for dust/particulate monitoring?

How can I monitor fugitive dust in multiple locations throughout my plant?

Combustible dust fires and explosions have proven some of the most devastating industrial accidents in recent decades. In many cases, the greatest contributor to dust accumulations that fueled the most powerful conflagrations was fugitive dust. Despite the large contribution of fugitive dust to combustible dust incidents many facilities do not give it as much attention as direct dust emissions monitoring or source monitoring. In order to effectively control, prevent and protect against combustible dust hazards plants need to pay careful attention to ambient dust levels as well. 

Why Do Fugitive Dust Levels Matter So Much? 

Fugitive dust refers to dust that is generated by various processes that then disperses throughout a large area or even an entire plant. This differs from source emissions or localized dust buildup. For example, a malfunctioning conveyor system may spill dust onto the floor or generate airborne dust that settles relatively close by the source (for example within the same room). However, these localized sources may also generate airborne dust that then travels throughout the facility. When multiple sources combine it creates a high concentration of airborne dust throughout the facility. This general level of airborne dust is what we refer to as ambient dust levels. High ambient dust levels can then lead to worker health and safety hazards as well as contribute to dust accumulations in multiple locations in a plant creating additional housekeeping work in order to properly control it.
