To investigate the potential of carbon emission monitoring technology in optimizing thermal power unit operations beyond the"double control"of emissions in thermal power enterprises,an F-class gas-steam combined cycle unit where a CO2 monitoring system is installed at the tail chimney is selected to be discussed.Research is conducted using online fuel monitoring data from the front pressure regulating station and flue gas monitoring data from the rear chimney environmental protection measurement point.The results reveal that,in the high-load section,the flue gas monitoring carbon emission rate is consistently higher than the fuel monitoring rate,although both curves exhibit similar trends,indicating comparable yet offsetting data.For units operating at medium loads,atmospheric conditions are crucial.Elevated temperatures may increase heat loss,while reduced air pressure can minimize compressor energy consumption,thereby decreasing the unit's instantaneous carbon emission intensity.Among various parameters,adjusting the turbine expansion ratio,compressor pressure ratio,and steam fuel power ratio could be effective strategies to minimize carbon emissions without altering the unit load.
