Abstract

To determine the concentration and behavior of fine particulate matter PM25 from municipal solid waste incineration sizeclassified dust samples were collected from four incineration facilities using cascade impactors The total dust and PM25 concentrations were 17–236 and 0–104 μg/Nm3 respectively in the flue gas sampled from the stacks The total dust concentration in the flue gas was 1/50 or less of the concentrations measured previously in the same facilities with the operation of an electrostatic precipitator Each air pollution control device used in the facilities was evaluated from the perspective of PM25 removal A bag filter activated carbon tower and selective catalytic reduction were all considered to be effective The removal efficiency of PM25 was more than 9999  Analysis of the particle size distributions of the dust identified two peaks around 1 and 10 μm at the inlet of the BF Based on the results of an elemental analysis of the dust the particle size distributions of each element were also calculated As a result the emission of PM25 as primary particles from a stateoftheart municipal solid waste incinerator was estimated to be very lowThis study was supported by research grants from the Osaka Bay Regional Offshore Environmental Improvement Center and The Environment Research and Technology Development Fund K122106 We thank Shimadzu TechnoResearch Inc and relevant local governments for help with sampling at MSWI facilities
