ABSTRACT. The penetration of fly ash particles through an electrostatic precipitator (ESP) was measured as a function of particle size in the range of 0.02–0.7 μm (divided into 32 mobility channels) with a combination of an electrostatic classifier (DMA) In 2010, coal accounted for more than 76.5% of China’s energy production and about Full article: Analysis and discussion on formation and control

1. Introduction. Coal is one of the main energy sources at present and for a long time to come (Lin et al., 2019, Miao et al., 2021, Azam and Mishra, 2019).In many industrial scenarios, coal may cover various equipment in the form of dust and remain in the environment where coal is transported and stored (Shi et al., 2021a, Amyotte, Fig. 3: Peak pressure of antipodal ejecta sourced from the impactor as a function of their flight time.

In opposition to Fig. 6, Fig. 7 shows that some features of impact spatter patterns cannot be singly related to impact velocity and may also depend on impact energy.
