Dust is emitted from each type of bagging process during final filling when dust-laden air is displaced from the bag by the ammonium nitrate. The potential for emissions during bagging is greater for coated than for uncoated material.

Research on Characteristic Parameters of Coal-dust ...

1/1/2012 · Smaller the coal-dust partical size is, more easily the dust is ignited, and lower the minimum ignition is, which is between (793-803) K at the particle size of (25-48)µm. (2) Explosion limit concentration of coal-dust is between (20-30) g·m -3 at an ambient temperature of (293±5)K and dusting pressure of 2MPa.

Investigation of sulfate and nitrate formation on mineral ...

12/1/2005 · The yields of nitrate and sulfate formation on mineral dust particles increase with the [Ca]/[Si] ratio, which is greater in soil dust than in coal fly ash. Nitrate is bound to Ca-richest soil dust particles. Ammonium was found in dust particles containing soil organic matter, which also hold the largest amount of sulfate.
