Methodology
The heat exchanger will operate at one or more OPS for long enough to be
considered steady state operation, such that Base Operating Point Set (BOPS) and
Comparative Operation Point Set (COPS) may be read and saved for comparative
Performance Factor calculations.
Training
During the Training Period (TP), input plant data sets will be read, and an associated
Ebaseline and Ubaseline will be calculated. A BOP will be created for each stable
significantly different operating level of the heat exchanger. Significantly different
will be determined by a percentage (Delta BOPS) that is configured by the user or
greater change in any one or more of the following variables:
