Utilities have been cleaning their boilers for many years using either steam or high-pressure air. In the past, when air was used, due to the size of the boilers and the reasonable quality of fuel used, a relatively small amount of cleaning was required.
The plant upgrades, in combination with a progressive management strategy, allows the plant to consume less energy and reduce its reliance on outside contractors for biosolids removal, resulting in total operational savings of approximately \$60,000 per year. The plant is also positioned to efficiently manage the area’s wastewater for decades to come.
Industry standards serve a very important purpose for the end users of compressed air equipment. If the standards are well written, they can help to promote the equipment that they govern, as long as the equipment manufacturers properly apply and promote the standards.
This steel processing facility has been operating for over one hundred years. This facility is part of a large corporation with numerous plants around the world. This audit focused on the compressed air system on one side of the Works which we will call the “North Plant”.
Relatively few people realize that for a variety of industrial manufacturing applications, from air knife drying to simple blow-off nozzles, the use of high pressure compressed air that bleeds into the atmosphere represents a significant waste of energy.
