Achieved results of the CO, NO, and SO2 concentrations in the exhaust gas were related to the dry flue gas stream containing 10% oxygen and standard conditions (mg•m-3) at 0 °C and 1013 mbar according to the guidelines
contained in PN-EN 303-5:2012. The collected data were statistically analyzed in STATISTICA 10.0 using
