    and trying to evaluate all of them is a lot of work. However, for boilers fired with natural gas and fuel oil, many of the losses do not apply, and others are small enough to be rolled into an "unaccounted for" category for which a value, e.g., 0.2%, can be assumed. This leaves three main losses to be considered as shown in Poster App 1-2Learn More
