One of the standard design principles for ventilation of a building with a powered ventilation system is calculating air flow based on an air change rate. The activities inside or the purpose of the building will determine what is an appropriate air change rate. The air flow to be provided by the ventilation fans is …

Winter is here for most parts of the U.S. and for gas turbine operators, that means it is time to make sure that your anti-icing system is heating well at the correct times. The purpose of an anti-icing system is to prevent ice from forming on inlet air components. Ice build-up from a poorly performing …

In the third and final part of this article, we are going to discuss calculating total static pressure of the dust collection system. Total Static Pressure Each capture point, transition, branch and elbow in the ductwork will resist the flow of air. Each of these points will have an air resistance coefficient based on their …

In the second part of this three part series on Dust Collection System Design, we are going to discuss how to determine and maintain transport velocity. After dust particles are captured, the proper transport velocity ensures that the dust particles will be conveyed through the duct work without clogging from the capture point to the …

The National Fire Protection Association has recently revised its Standard on the Fundamentals of Combustible Dust – NFPA 652. According to the standard’s 2019 Edition, all dust collection systems, new or existing, are subject to a dust control plan as a part of an overall Dust Hazard Analysis (DHA). If you need to add or …

When I’m working on the design of a powered ventilation system for a building, I’m reminded of the song by David Bowie and Freddie Mercury called Under Pressure. The song deals with the daily pressures of life and love, but it makes me think about whether the building should have positive or negative air pressure. …

Electric motors are becoming the preferred choice for gas pipeline compressor stations. But how do you keep a 20,000 horsepower electric motor cool? We’ll discuss two of the factors that must go into the proper design of an air based motor cooling system to keep these large electric motors running efficiently. Removing Heat Load An …

We often have customers tell us that they only want to install large industrial ceiling fans also known as HVLS fans (high velocity low speed). These fans are a good solution for providing spot cooling to workers. We agree that keeping people cool in an unairconditioned facility is important because it increases productivity. Benefits and …

In the second part of this article on Harnessing the Wind, we are going to take what we learned about wind power in Part 1 and apply it to the design of a Powered Ventilation System design. System Design We now know that wind will create positive and negative pressure around a building. The performance …
