Abstract
Tracking utility and process heater efficiency
leads to increased operator awareness and decreased
fuel bills. A review of the Heat Loss and
Input/Output methods of efficiency analyses is
presented, along with a discussion of their
relative accuracy. Examples cited include refinery
mixed fuel gas, coal, and chemical recovery fueled
applications, using HHV and LHV calculations. The
techniques presented can be applied to improve
operator awareness, monitor equipment performance,
and evaluate capital improvement opportunities.
