4 Important Dust Collector Insights that Differential Pressure Can't Provide

Differential Pressure - Not necessarily the best parameter for dust collector/baghouse monitoring

DP is the king of dust collector monitoring metrics. However, some users have come to think that it is the ONLY metric to monitor on an industrial dust collector. This certainly is not the case…especially as the size and complexity of the system increases. Here are 4 important areas for which differential pressure cannot provide adequate insight.

9 Baghouse Details to Check When Differential Pressure Falls or Rises

Differential Pressure is a Critical Baghouse Performance Metric

Successfully operating your dust collector means carefully monitoring the differential pressure on each unit. Differential pressure is the principal operating metric used to monitor performance of a dust collector. 

Most modern collectors operate at peak collection efficiency between 2” - 6” of differential pressure. For this reason, many air permits (as well as operating documentation) specify a DP range for the collector "not to exceed" in order to achieve emissions compliance. This is combined with other performance considerations, such as rising or falling airflow throughout the system, to provide an operating view that is monitored in parallel with the emissions output readings. 

What to Do When DP is too High or too Low?

Why are MACT Standards Only for Certain Industries?

Let's Get Real About MACT

Ask any environmental compliance engineer what their biggest worry is and they will likely mention something involving MACT (maximum achievable control technology) standards. As MACT standards come to cover more and more industries, many facilities have found achieving compliance to be a significant challenge. Frequently they find that under investment in air pollution control over a number of years substantially complicates their compliance. Some have held out for political change that they assumed would lead to a revocation of these standards. Although the MACT program is firmly established by law and not subject to any executive directives or revision like some other standards, they've built programs of minimal compliance assuming that MACT would be reversed. It hasn't. It's exceedingly unlikely that it will.

Using Material Flow Monitoring to Prevent Damage to Filters Due to Sudden Shifts in Air / Material Balance

Real World Complications

When unloading bulk material, sudden changes in air flow can create complications for material conveying systems. Rapid increases in material flows, or high volume air flow as material flow suddenly slows, can damage filters within the system filter receiver. Often this change occurs quickly, and even if operators are diligently observing, they may not react quickly enough to prevent damage.

How can plants avoid these issues and prevent damaging their filters?   

Common Causes of Sudden Increases in Flow Rates

In most cases, there are several causes of sudden increased material flow.

3 Tips to Reduce Product Loss Due to Breakage in Pneumatic Conveying of Food

Pneumatic Conveying Convenience and Flaws

Many industries use pneumatic conveying as part of their manufacturing process. This includes many food processing and manufacturing plants as well. It's often used for the conveying of certain "dusty" food ingredients such as grains and sugar which pose certain well documented challenges including combustible dust hazards, sanitary or flow rate control.

Planning Baghouse Filter Media Replacement to Reduce Cost & Downtime

Just because...it's time

Many plants change their baghouse filters based on a firm schedule. Others prefer to wait until the filters begin to show signs of leaking and then they replace them. Others use differential pressure as a guide, replacing the filters once the DP begins to trend above a certain level. And others simply wait until a reportable event, citation from an air quality inspector or massive loss in system suction (process flow) before taking action. What is the best method for scheduling filter replacement?

Is Triboelectric Stack Monitoring an Alternative to EPA Method 9?

Best Reasonable Solution for Emissions Monitoring

Many plants continue to use EPA Method 9 visual observations as their primary dust collector monitoring methodology. Even as newer plants have already moved on to modern monitoring technologies, such as triboelectric dust monitoring, these plants continue to hold fast to their Method 9 CAM plans. Does triboelectric dust emissions monitoring really provide a realistic alternative to visual observation? In many cases, visual observations were the most accurate and feasible solution at the time the air permit was written. And many are still following this method today. But technology has advanced significantly and today visual observation is less reliable, less accurate and substantially more labor intensive compared to electronic instruments.

Predictive, Indicative & Alert Indicators - Baghouse Monitoring Metrics

Direct and Indirect Dust Collector Performance Metrics

On smaller dust collection systems, differential pressure often is the only metric used by operators to monitor the performance and condition of the system. For smaller systems this often proves sufficient. However, as systems get larger and more complex, plants usually start including additional monitoring metrics into the mix with the goal of early warning and predictive monitoring to reduce down-time, prevent reportable incidents and manage the maintenance burden and costs.
