Is Water the Best Coal Dust Suppressant MinTech

Water-only coal dust suppression systems use high volumes of water to wet coal fines and temporarily adhere them to larger coal pieces in order to prevent the fines from becoming airborne. This massive addition of water robs coal of its BTUs (heating value), causes plugging in chutes and hoppers, and creates a slippery environment.

Surfactant-aided coal dust suppression: A review of

Oct 15, 2018 Traditional coal dust suppression methods, such as the use of ventilation and water spray with plain water, were considered not adequate to meet the standard coal dust PEL (Harrold, 1979). Therefore, increasing attention was paid to research related to surfactant aided water spray coal dust suppression technology.

Coal dust Wikipedia

Coal dust is a fine powdered form of coal, which is created by the crushing, grinding, or pulverizing of coal. Because of the brittle nature of coal, coal dust can be created during mining, transportation, or by mechanically handling coal.It is a form of fugitive dust.. Grinding coal to dust before combusting it improves the speed and efficiency of burning and makes the coal easier to handle.

Coal Dust Remediation FEECO International Inc.

Since coal is a hydrophobic material, meaning it is not attracted to water, various chemicals are often used to aid in suppression techniques. Coal dust is suppressed as it’s made, and then often again throughout processing, typically at transfer points where dust may again be generated, such as when transferring from one conveyor to another.
