Summary of Research and Application of Continuous Monitoring Technology for Carbon Emissions From Thermal Power Units

Abstract

ObjectivesThe accurate measurement of CO2 emission is of great significance for carbon reduction and the operation of carbon market. Continuous monitoring technology is an important means of measuring carbon emissions from flue gas of thermal power units. Compared with the accounting method, it has the advantages of less human intervention, high automation, and strong timeliness.The research progress and application status of continuous monitoring technology for carbon emissions was reviewed, aiming to provide reference for the power generation industry to establish a more perfect carbon emission measurement method system and carbon emission data management system.MethodsThe research progress of CO2 concentration monitoring technology and flow monitoring technology in flue gas was emphasized. The current application status of continuous carbon emission monitoring technology in thermal power plants in the United States, the European Union and China was analyzed. The comparative research situation between continuous monitoring method and accounting method was discussed.ConclusionsThe technical challenge faced by continuous carbon emission monitoring technology is the accurate monitoring of flue gas flow rate. There are great differences in the magnitude and accuracy of carbon emissions obtained by continuous monitoring and accounting methods. Based on the current situation of continuous monitoring of carbon emissions in China, it is recommended to improve the relevant policies and standard system as soon as possible, conduct in-depth technological research, and expand technological applications.
