+
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.

+
Water-based dust suppression systems can add anywhere from 20 40 pounds of additional moisture per ton of coal, which soaks up valuable heating content of the coal. Now you have to use your energy evaporating all the moisture you just added rather than creating more heat.
+
In general, for a given system with coal dust dispersed in air throughout its volume refer to Figure 1, Time 0, the ignition source ignites adjacent suspended coal dust. Energy transfer from the burning coal to the next increment of unburned dust is by ordinary heat transfer, and if sufficient, will ignite the unburned dust.
