moisture content where coal produces dust

moisture content of pulverized coal dust

In order to determine whether enough rock dust is applied, 30 CFR1 § 75.403, Maintenance of Incombustible Content of Rock Dust, requires at least 80% incombustible content on the roof, ribs, and floor of underground coal mines. 30 CFR § 75.403-1 further defines the incombustible content as follows: "Moisture contained in the combined coal ...

Experimental investigations on the roles of moisture in ...

2014-9-1  Explosion behaviors of coal dusts were systematically investigated to focus on the roles of moisture in dust explosion. It is found that, when the moisture content is lower, the explosion parameters (P ex, (dp/dt) ex and MEC) basically keep a linear relationship with the moisture content.With the further increase of moisture content, the moisture would gradually agglomerate fine particles by ...
