| 1. A method for determining a best operating practice for minimizing emissions of NOx at a fossil fuel-fired plant, comprising the steps of:
reviewing normal operation data for a normal configuration of equipment at said plant;
specifying a time-dependent perturbation based on the review of said normal operation data;
applying said perturbation to one or more fuel inputs to give a signature in said normal operation data;
acquiring measured response data from said fuel inputs with said signature to form a perturbation test data set;
analyzing said perturbation test data set, further comprising the steps of:
filtering said perturbation test data set, wherein said perturbation test data set is filtered by applying a signature perturbation
waveform formed by said signature in said normal operation data; and,
carrying out matrix calculations for said perturbation test data set, wherein a mass per unit energy value is quantified to
allow said normal configuration of said equipment to be optimized to reduce said NOx without changing said normal configuration to determine said best operating practice.
