2020年9月22日 2.1.1 Fly Ash Handling . The following dust control measures are implemented at the Station to minimize fugitive dust emissions during fly ash loading operations: 1) Trucks drive under the fly ash silos and are loaded by pugmill style mixers directly under the fly ash hoppers. The ash is wet conditioned in the pug-mill mixers, which

2020年9月29日 Fugitive dust level is measured by the diameter of particulate matter smaller than 10 μm (PM 10) or particulate matter smaller than 2.5 μm (PM 2.5) in the mining industry. The size of a particle determines how deep in the respiratory system it can travel. The smaller the size of the particle; the deeper in the tract it can advance.
