Abstract:
A method for determining flue gas recirculation percentage comprising:measuring a first temperature (T.sub.1) at a first temperature sensor in an air inlet line for providing air to a combustion generator;measuring a second temperature (T.sub.2) at a second temperature sensor in a recirculation line coupled between the air inlet line and an exhaust stack of the combustion generator;measuring a third temperature (T.sub.3) at a third temperature sensor in a line coupled between a blower and a burner section of the combustion generator;calculating a temperature factor (T.sub.3 ') by subtracting the temperature of said blower from T.sub.3 ; andcalculating the flue gas recirculation (FGR) percentage in accordance with the following equation ##EQU11##
