Patent ID: 7428838

Claim:
A method for calibrating a system configured to analyze exhaust gas produced by a fluid consuming source, comprising: directing a first flow of exhaust gas toward an analyzer, the analyzer configured to measure at least one component; establishing a first value indicative of a measurement of the at least one component within the first flow of exhaust gas; removing a first quantity of fluid from the fluid consuming source; delivering a second quantity of fluid into the first flow of exhaust gas, the second quantity of fluid being a portion of the first quantity of fluid; at least partially combusting the first flow of exhaust gas and the first quantity of fluid upstream of the analyzer; establishing a second value indicative of a measurement of the at least one component within the exhaust gas and the at least a portion of the first quantity of fluid; and calculating a calibration coefficient for the system as a function of a difference between the first value and the second value.
