Abstract: The operation of a fossil-fueled thermal system is quantified by a method for determining correction factors to Choice Operating Parameters, including effluent CO2 and 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.

Abstract: The operation of a fossil-fueled thermal system is quantified by obtaining an unusually accurate boiler efficiency. Such a boiler efficiency is dependent on the calorimetric temperature at which the fuel's heating value is determined.

Abstract: The operation of a fossil-fueled thermal system is quantified by obtaining a reference fuel chemistry before on-line operation, and thereafter operating on-line. In on-line operation, a set of measurable operating parameters is measured, including at least effluent concentrations of O2 and CO2, and optionally the concentration of effluent H2O and the concentration of effluent SO2. An indicated Air/Fuel ratio is obtained, as are the ambient concentration of O2, and air pre-heater leakage and dilution factors. The fuel ash and fuel water are calculated, and the complete As-Fired fuel chemistry is calculated. From the complete As-Fired fuel chemistry, the pertinent systems parameters such as reference fuel heating value, boiler efficiency, system efficiency, fuel flow rate, total effluent flow rate, individual effluent flow rates, and individual emission rates are determined in a fully consistent manner. The Method has been reduced to software which is fully benchmarked and operational.
