【Abstract】 The measurement of flue gas flowrate is crucial for the accuracy of stationary source carbon emission measurement, but it is influenced by various factors. By summarizing and analyzing the current mainstream flue gas velocity measurement technology and its application status, specific improvement measures were proposed from three dimensions, including measurement principle, measurement method, and measurement device, in response to the problems in on-site measurement. Key sources of error in flue gas flowrate measurement were identified, and targeted response strategies were developed, which effectively improved the accuracy and reliability of flue gas flowrate measurement. These strategies provide important technical references for environmental comparison testing, on-site calibration of flue gas flowmeters, etc., which helps to enhancing the technical proficiency and data quality of on-site measurement operations. Through the optimization of measurement principles, methods, and devices, contributions have been made to the development of stationary source carbon emission measurement technology.更多还原
