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.
