The factors influencing dust emissions are numerous and the internal mechanisms and interactions are still under in-depth research. This study will analyze the dust emission patterns during the unloading process of ore powder from the aspects of moisture content, mass flow rate, and ambient wind speed.
The controlled emission factor for PM-10 was developed from References 9 and 10. d The controlled PM emission factor was developed from Reference 10 and Reference 12, whereas the controlled PM-10 emission factor was developed from only Reference 10. e Emission factors were developed by using the AP-42 Section 13.2.4, Aggregate and Sand Transfer

What is an Emission Factor? An emission factor (EF) is a coefficient that describes the rate at which a given activity releases greenhouse gases (GHGs) into the atmosphere. They are also referred to as conversion factors, emission intensity and carbon intensity. How Global Warming is Measured. The most well-known greenhouse gas is CO 2. It is ...
