PM10 AND PM2.5 – THE EFFECTS, REGULATIONS AND CONTROLLING THIS FINE PARTICULATE
Particulate Matter 10 micrometers in diameter or smaller (PM10) and Particulate Matter 2.5 micrometers (often called microns) in diameter or smaller (PM2.5) are subject to regulation under the NAAQS, National Ambient Air Quality Standards.Read More »
How do I calculate the optimum flow rate of compressed air for cleaning filter bags?
How do I calculate the optimum flow rate of compressed air, supplied at 7 MPa, for cleaning filter bags in a jet pulse dust collector baghouse?
The compressed air usage for a pulse jet baghouse is determined by: pulse valve size, pulse pressure, duration of pulse (how long the valve is open), frequency of pulses (interval time between pulses), number of pulse valves pulses per output of the baghouse controller.
What’s in your Filter Bag?
If you have an old, underperforming dust collector, baghouse or fabric filter, it is most likely still outfitted with conventional needle felt filter bags. And if everything has remained the same in your process, over a period of time you have most likely been forced to just live with the performance that comes with them. However, if your process has changed, higher air flows, increased dust loading or other operating conditions have impacted the performance of your collector.Read More »
Improved inlet design energizes baghouse performance
Ask any maintenance person who works around baghouses and they will tell you one of the most frustrating things they have to do, is not just change filter bags, but the same filter bags over and over again. Why? Because; in many fabric filter systems the impact of inlet design is overlooked. In fact, inlet velocities and misdirected air flow into a dust collector can be a major cause of reduced bag life and poor collector performance.Read More »
