Solution

Coal dust becomes a serious issue during the unloading of coal from barges to stockpiles, especially in hot and dry conditions. This dust problem can pose risks to the health and safety of workers, pollute the environment, and affect commercial operations. Power plants can lose up to 3% of their total coal annually due to the dispersion of coal dust..

Solution
The solution to tackling coal dust issues is the application of coal dust suppression chemicals using the appropriate spraying equipment.

Not only does the type of coal chemical matter, but the equipment system used also significantly impacts the success in addressing this issue.

Both polymer-based and surfactant-based coal treatments work by wetting the coal surface and preventing dust from becoming airborne. Surfactants enhance the water’s ability to wet the coal, while polymers work by coating the coal surface. Both methods effectively prevent dust dispersion.

In addition to addressing dust issues, Eonchemicals also offers coal treatment products to tackle spontaneous combustion problems in coal. Feel free to chat via WhatsApp for a free consultation. 

Succes Story

One of our power generation customers in Sulawesi faced coal dust issues during the unloading process from barges and when stockpiling. This dust significantly disrupted operations and polluted the environment.

Eonchemicals provided a solution by spraying polymer-based chemicals, specifically CoalGuard 575, using the Eon Coal Sprayer System (ECSS). CoalGuard 575 was sprayed onto the coal on the conveyor belt before it was stockpiled. This solution effectively prevented dust from becoming airborne during stockpiling, allowing workers to operate more safely and creating a cleaner environment.

Application of CoalGuard 575

• Dilute CoalGuard 575 at a ratio of 1:100 with water (1%)
• The dilution is done automatically using a dosing pump on the ECSS (Eon Coal Sprayer System)
• Apply the CoalGuard 575 solution at a flow rate of 10 L/MT of coal
• Use a special nozzle and position it correctly for optimal results

CoalGuard 575 is a safe, environmentally friendly coal dust suppressant that does not affect the combustion process in boilers. This has been proven through various parameter tests, including:

• Biodegradability test
• LC50, LD50, and heavy metal content (TCLP) tests
• Thermogravimetric analysis
