بيت /calculation of emission rate fugitive dust
Fugitive Dust Fugitive Dust is a Particulate Matter (PM) comprised of soil minerals that are suspended in the air by wind action and/or human activities. Fugitive dust, or dust not coming from a combustion source, accounts for 90% of all primary PM 10 emissions in California. Fugitive Dust .

The fPM emission fluxes were calculated using the Fugitive Dust Model (FDM) in an iterative manner and were fitted to a power function, which expresses the wind velocity dependence. The power factors were estimated as,, and for the four different size classes of particles ≤, –6, 6–10 and ≤10 μm, respectively.

Fugitive Dust. Dust is particulate matter (PM) consisting of very small liquid and solid particles. Fugitive dust is PM suspended in the air primarily from soil that has been disturbed by wind or human activities, such as earthmoving and vehicular/equipment traffic on unpaved surfaces.

While an emission rate of lbs/hr would exceed the acute trigger level for EGME, the emission rate for the source operating only 2 hrs/day and averaged over the 6hour averaging period found in Table 1 for EGME, results in an hourly emission rate of lbs/hr, which is below the acute trigger level.

Abstract Emissions from fugitive dust due to erosion of "natural" windblown surfaces are an increasingly important part of PM 10 (particulate matter with sizes of 10 μm aerodynamic diameter) emission inventories. These inventories are particularly important to State Implementation Plans (SIP), the plan required for each state to file with the Federal government indicating how they will ...
