Experimental Studies on Aerosol Size Spectroscopy with Multijet Low-PressureInertial Impactors

摘要

Factors associated with the determination of continuous aerosol size distributionfunctions with compressible flow low-pressure impactors, including the determination of the kernel functions for the submicron stages, data inversion and the validity of the determined continuous submicron size distribution functions, were studied. Methods to determine mass and composition size distributions of aerosols emitted from combustion processes with low-pressure impactors were developed. Impactors were used to characterize aerosols emitted from the real-scale hospital refuse incineration and pulverized coal combustion processes.
