A systems approach entails looking at the entire com pressed air system from start to finish when considering optimization.
Compressed air system design calculations pdf.
250 nm3 hour is the same as 4200 nl min normal liter per minute or 150 scfpm standard cubic.
Plant air compressor systems can vary in size from a small unit of 5 horsepower hp to huge systems with more than 50 000 hp.
Here s an example calculation using the compressed air pipe sizing table table 1 and the equivalent pipe length table table 2.
The compressed air pipe routing design and dimensions are important factors for the efficiency reliability and cost of compressed air production.
Let s say we have a rotary screw compressor of 30 kw that can supply 250 nm3 hour normal cubic meters per hour.
Taking a systems approach can help you devise solutions to these challenges.
2 purpose of this reference guide.
Take a systems approach to compressed air we have clearly established that compressed air systems are inefficient expensive and often misused.
Compressed air systems often operate inefficiently using an unnecessary and expensive amount of energy.
In many cases the compressed air system is so vital that the facility cannot operate without it.
This guidebook does not and is not intended to replace equipment manuals or maintenance procedures.
In many industrial facilities air compressors use more electricity than any other type of equipment.
Readers are cautioned to use proper health safety and.
Occasionally a large pressure drop in the piping system is compensated by adjusting or increasing the working pressure of the compressor from for example 7 bar to 8 bar.
Analyzing and optimizing compressed air systems.
