There are usually two main problems coal handling, namely dust and spontaneous combustion. If the customer’s main problem only focuses on dust, then the chemical they need is dust suppressant. In the meantime, if the problem is the sponcomb, or spontaneous combustion, then the chemical they should use is a sponcomb inhibitor.
Since this chemical requires a tool to apply it on the coal, EON developed EON CSS (Coal Spraying System). Judging from its work mechanics, the spraying system is divided into two types namely dry fog and wet fog. Dry fog means spraying with smaller grains of water (<10 micron). We can also call this process fogging because the main target is to wet the air around coal to suppress dust. On the other hand, wet fog sprays larger grains of water than dry fog because the main target is to wet the coal. It means that the system sprays the solution directly to the coal in order to coat the coal.
In its application, as a dust suppressant, we combine dry fog with a surfactant-based dust suppressor chemical. To point out, we would not recommend combining it with any polymer-based chemicals. Unlike dry fog, wet fog works as a sponcomb deterrent where it is combined with sponcomb inhibitor chemical. It works by coating the coal directly to break coal’s direct contact with oxygen.
