The operation of a fossil-fueled thermal system is quantified by a method for determining correction factors to Choice Operating Parameters, including effluent CO2and other parameters, such that combustion stoichiometric consistency and thermodynamic conservations are both achieved. Correcting Choice Operating Parameters is accomplished through multidimensional einimization techniques operating on certain System Effect Parameters. The corrected Choice Operating Parameters may then be supplied to Input/Loss methods as used to monitor and improve system heat rate.
