The targets of this research is to study on the particle size distribution with two standard test methods American Method 201A and Japanese JIS K0302 and establish particle emission characteristics of stack flue gas in nine industries. This research examined the differences between two standard test methods American Method 201A and Japanese JIS K0302 of particle diameter analysis and compared the merit and shortcoming of the two methods. Moreover, this research further explored the influence of particulate emission in flue gas on the atmospheric PM10. To rationalize the standards and regulations of air pollutant emissions, it is necessary to examine the particulate emission characteristics of flue gas. The sampling method used sampling probe to extract fine particles in the flue gas and then employed gravimetric method to calculate the concentration of discharged particles. The contribution of PM10 emission from stack was also determined in this study. Results showed that the food industry had the highest PM10 concentration, 114.7 mg/Nm3, whereas the cement industry had the lowest PM10 concentration, 15.2 mg/Nm3. Furthermore, papermaking industry had the highest PM10/TSP ratio, 0.88 and the brick kiln industry has the lowest PM10/TSP ratio, 0.67. The ratio of using Japanese standard sampling method was little smaller than that of using American standard sampling method. The PM10 variation at cement plant with USEPA Method 201A and JIS K0302 is the smallest, as small as 13% and 5%, respectively.
