High on the to-do list of every facility operator in the Country, public or private, is a mandate to reduce operating costs. One place to accomplish this, often overlooked, is the boiler house. There, inexpensive modifications to the boilers may well achieve significant fuel savings as well as lower maintenance costs. With a short payback, the impact is soon seen at the bottom line. Putting these changes into effect can be expected to have an additional benefit – achieving compliance with future more stringent environmental regulations will be easier and less expensive.
