Compressed Air Best Practices - November 2008 - (Page 15) Focus Industry STEEL & METALS | 11–12/08 | Demand Side Audit Blow-Off Air Projects There are 400+ locations in this steel processing facility where blow-off air is being used. Compressed air is being consumed at the rate of 3,800 scfm at a cost of $300,000 per year. We recommend modifying these applications with simple solutions, which will cost only a total of $15,000 to purchase and implement. One example is in the Hot Mill/Furnace. Blow-air is used to clean and cool the inspection glass. There are 56 locations using an average of 25 scfm each for a total of 1,400 scfm. They are at 100% utilization and are costing the facility $114,800 per year in energy costs. We recommend installing fixed-air amplifiers with 25:1 amplification. These nozzles will use up to 8 scfm each and flow 125 scfm of ambient or surround air at the glass. The 56 nozzles will use a total of 448 scfm at an annual energy cost of $36,736. The net energy savings will be $78,064 per year. The cost of these nozzles is $1,500. The average net compressed air usage reduction will be 952 scfm. It is possible that with this performance, you may not need to use as many blow offs in total in which case, the savings will be greater. With a few minor exceptions, most of the leaks could not have been found without the use of an ultrasonic leak detector and a trained operator.
