1. A method for quantifying the operation of a fossil-fired system, the method comprising the steps of:

  • obtaining an L Factor;

    determining a correction to the L Factor which converts its applicability from theoretical combustion to combustion associated with the fossil-fired system, and if applicable the correction for the system heating value base, and if applicable conversion to a wet-base L Factor;

    combining the L Factor and the correction to the L Factor, resulting in a corrected L Factor;

    obtaining a total effluents flow rate from the fossil-fired system;

    obtaining a correction factor for the total effluents mass flow rate, resulting in a corrected total effluents mass flow rate; and

    dividing the corrected total effluents flow rate by the corrected L Factor, resulting in a total fuel energy flow of the system.
