Boiler Efficiency: Introduction and Methods of Calculation

Steam Basics – Boiler Efficiency. The Efficiency of a boiler should be an important part of a purchase evaluation since the annual cost of fuel can easily be 2 to 3 times the installed cost of the equipment. Therefore, a difference in efficiency and the resultant difference in fuel cost can easily offset a difference in capital cost. In many cases, the fuel savings in the first year alone can exceed a difference in capital cost and, of course, fuel …
