Coal combustion aerosols: a field study

In situ particle size classification with an in-stack compressible flow low-pressure impactor was applied to the mass and elemental size distributions of aerosols emitted from a pulverized coal-fired boiler. Aerosols were collected after the electrostatic precipitator in the 0.01-11 mu m size range....

Summary:In situ particle size classification with an in-stack compressible flow low-pressure impactor was applied to the mass and elemental size distributions of aerosols emitted from a pulverized coal-fired boiler. Aerosols were collected after the electrostatic precipitator in the 0.01-11 mu m size range. Bimodal mass and elemental size distributions were recorded for sodium, magnesium, aluminum, copper, lead, and other elements. Geometric mass mean diameters of fine and coarse modes were about 0.05 and 2 mu m, respectively.
