The continuous emission monitoring system (CEMS) has become an essential tool for providing high temporal resolution and dynamic pollutant emission data. However, there is a lack of application and validation of CEMS in small-scale industrial sectors using industrial furnaces with unstable emissions. Using tobacco curing industry as a case, we applied CEMS and field tests to monitor emission dynamics from tobacco curing barns of four typical fuels during tobacco curing season from July to September 2023. The results show that CEMS monitoring data is mostly consistent with field tests results, with average emission concentrations differ by 0.13-7.8 %.

However, there is a lack of application and validation of CEMS in small-scale industrial sectors using industrial furnaces with unstable emissions. Using tobacco curing industry as a case, we applied CEMS and field tests to monitor emission dynamics from tobacco curing barns of four typical fuels during tobacco curing season from July to September 2023. The results show that CEMS monitoring data is mostly consistent with field tests results, with average emission concentrations differ by 0.13-7.8 %. The CEMS provides complete records of periodic emission dynamics of CO <subscript>2</subscript> , SO <subscript>2</subscript> , NO <subscript>X</subscript> and CO. The emission concentrations of carbon and pollutants vary by up to 1-2 orders of magnitude, accompanied by complex variability. We further combined CEMS data with fuel consumption and dry weight of tobacco produced to generate emission factors. Notably, biomass fuel requires no modifications to feeding or combustion equipment and reduces pollutant emissions by over 50 % compared to coal, making it an ideal alternative. Our findings provide essential insights for estimating emissions of China's tobacco curing industry and for developing future policies of industrial furnaces.<br /> (Copyright © 2025 Elsevier Ltd.
