Coal washing The raw coal extracted out from the coal mine is processed through different techniques to achieve the desired qualities. These result in higher economic value of run of-mine (ROM) coal.
The major control technique used to reduce these emissions is water wetting. Another technique that applies to unloading, conveying, crushing, and screening operations involves enclosing the process area and circulating air from the area through fabric filters. Uncontrolled emission factors for various types of fugitive sources in coal cleaning facilities can be developed from the equations ...
