1. A method for quantifying the operation of a fossil-fired thermal system in which a fuel chemistry and fuel heating value of the fossil-fired thermal system are determined based on real time data acquired through a monitoring the fossil-fired thermal system, the method comprising the steps of:

  • selecting an Input/Loss Method which is capable of determining a complete As-Fired fuel chemistry, including fuel water and fuel ash, as a function of reference fuel characteristics, explicit mathematical models of the combustion process, a set of measurable operating parameters, an obtained effluent H2O, an obtained Air/Fuel ratio, an ambient concentration of O2 and an air pre-heater leakage factor, and also capable of determining a consistent As-Fired fuel heating value as a function of the complete As-Fired fuel chemistry and the reference fuel characteristics, resulting in a selected Input/Loss Method capable of determining the fuel chemistry and fuel heating value;

    obtaining a set of multiple data collections, each collection consisting of individual data points describing the fossil-fired thermal system;

    determining a set of time delays for individual data points associated with the step of obtaining the set of multiple data collections;

    determining a synchronous collection of data dependent on the set of time delays for individual data points and the set of multiple data collections; and

    determining the fuel chemistry and fuel heating value of the fossil-fired thermal system based on the selected Input/Loss Method and the synchronous collection of data.
