AGGLOMERATION OF COAL MINE DUST AND ITS

1988-1-1  Abstract. The result of a size analysis using a multistage impactor is the distribution of the aerodynamic sizes of a dust in its airborne state. The comparison of this result with the aerodynamic size distribution of the single particle state of the same dust indicates whether there are agglomerated particles in the airborne dust.

Elemental particle-size emissions from coal-fired

1978-1-1  Coal-fly-ash particles collected on coated and uncoated impaction substrates were analyzed by scanning electron microscope (SEM) techniques in combination with instrumental neutron activation analysis (INAA) to verify the sizes of particles collected and their elemental composition to estimate the significance of bounce-off and reentrainment onto back-up filters and to evaluate wall and interstage losses for the University of Washington MK III Source Test Cascade Impactor.
