Any business seeking to make operations more sustainable should take steps to fully understand the compressed air system calculate its true cost and implement.
Compressed air system design calculations pdf.
Take a systems approach to compressed air we have clearly established that compressed air systems are inefficient expensive and often misused.
In many cases the compressed air system is so vital that the facility cannot operate without it.
Analyzing and optimizing compressed air systems.
This guidebook does not and is not intended to replace equipment manuals or maintenance procedures.
A systems approach entails looking at the entire com pressed air system from start to finish when considering optimization.
Compressed air systems often operate inefficiently using an unnecessary and expensive amount of energy.
Here s an example calculation using the compressed air pipe sizing table table 1 and the equivalent pipe length table table 2.
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.
1 system overview 2 compressed air ratings 3 types of compressors 4 system design considerations 5 compressor controls 6 compressor sizing 7 system configuration 8 air quality 9 components of compressed air system 10 compressed air treatment 11 after coolers 12 dryers 13 compressed air filters 14 six levels of compressed air treatment quality.
250 nm3 hour is the same as 4200 nl min normal liter per minute or 150 scfpm standard cubic.
It is not a design guide for new or expanded air compressor systems.
Taking a systems approach can help you devise solutions to these challenges.
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.
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.
