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.

ANFO - Wikipedia

Chemistry. The chemistry of ANFO detonation is the reaction of ammonium nitrate with a long-chain alkane (C n H 2n+2) to form nitrogen, carbon dioxide, and water.In an ideal stoichiometrically balanced reaction, ANFO is composed of about 94.3% AN and 5.7% FO by weight. In practice, a slight excess of fuel oil is added, as underdosing results in reduced performance while overdosing merely ...

ammonium nitrate | Formula, Uses, & Facts | Britannica

Ammonium nitrate is a colourless crystalline substance (melting point 169.6 °C [337.3 °F]). It is highly soluble in water; heating of the water solution decomposes the salt to nitrous oxide (laughing gas). Because solid ammonium nitrate can undergo explosive decomposition when heated in a confined space, government regulations have been imposed on its shipment and storage.
