the concept is the same for commercial equipment.

<p class="MsoNormal">Can someone direct me to where I can find
an explanation of how the part-load boiler curves were
developed? I can find the formula coefficients for the
heat-input ratio in the BDLLIB.dat file and an explanation of
how to apply them in the DOE2 Engineer’s Manual. But how were
the formulas and coefficients developed? Are they based on
some study results described somewhere in the documentation? I
am seeing very little part-load degradation in performance
using the forced draft curve and I was wondering why. Thanks.
