摘要：

In order to study assessment methods compliance with emission limit of air pollutants for coal-fired power plants, on-line data of 278 coal-fired units over Jiangsu, Shandong, and Guangdong province for three months from the continuous emission monitoring system (CEMS) were collected. These data were analyzed statistically and compared based on different assessment methods. The results show that 1) according to the assessment method in Directive 2010/75/EU, more than 91% of 179 general units and more than 95% of 99 ultra-low units meet the requirement, respectively; 2) according to the assessment method of 30-day rolling average in CFR40-Part60-subpartDa of US, all units can meet the requirement; 3) according to the assessment method that 100% of hourly average values do not exceeds the relevant emission limit value, 48%~70% of the general units and 69%~88% of the ultra-low units meet the requirements from monthly statistics data, respectively; 4) while according to the assessment method that 99% of hourly average values do not exceeds the relevant emission limit value, the proportion of the units meeting the requirements increase significantly (i.e., the general units and the ultra-low units rise to 77%~89% and 91%~95%, respectively). The assessment method that 100% of hourly average values do not exceeds the relevant emission limit value is used in China currently. It is obvious stricter than that in US and EU.(i.e., long-term values of monthly or 30-day rolling average are forbidden to exceed the emission limit while short-term values of daily or hourly average can exceed in some certain conditions). The latter method is closer to the current situation of air pollution control in Chinese thermal power industry. Therefore, we suggest that Chinese government shall accept the assessment method that no monthly average values exceeds the relevant emission limit value and 95% of hourly average values do not exceeds the relevant emission limit value. © 2020 Chin.
