BossTek has helped the Port of Coeymans control fugitive particle emissions at the dock and in the industrial park using atomised mist technology.
Located along the Hudson River, the Port of Coeymans has employed two DustBoss DB-60 atomised mist cannons from BossTek for dust suppression in a variety of activities and applications. One machine is mobile, used to control particle emissions during the unloading and storage of bulk materials. The other is tower-mounted to suppress particulates at the metal scrap yard.
BossTek said this provides operators the versatility to address surface suppression and airborne control at different areas of the port, resulting in a drastic reduction in fugitive dust.
About 40-50 vessels per year arrive from Greece, Turkey, Egypt and Spain, delivering nearly 30,000t per week of clinker. When the ship arrives, large clamshell shovels controlled by tower cranes unload the material from the ship’s cargo hold, over the ship’s deck – from 7.5m to as high as 36.5m in the air –to a 6m-high hopper, which discharges into a 36t haul truck. The truck drives the material the short distance to the adjacent industrial park, where it is stored for further transport.
“The most dust was produced when the substance was dropped into the hopper, and although it has a bag house attached, a percentage would still escape,” explained Stephen Kelly, vice president, Sales and Business Development, Port of Coeymans.
“We realised that we also needed dust suppression for scrap metal storage and other operations in the industrial park. Our goal was to improve air quality for the safety of our employees and the surrounding community.”
Like many other facilities handling bulk materials, the Port of Coeymans limits fugitive dust emissions by employing a couple of simple methods. One is limiting the distance the dust-emitting cargo travels from the ship’s hold to the dock. This is done by using a clamshell shovel suspended from a crane to slowly unload the material into a tall portable hopper with a baghouse dust collection system.
To further mitigate dust, crane operators reduce the amount of material collected by the shovel. Although this extends the unloading time, it curbs the amount of material escaping from the top or sides of the shovel and thus further limits dust emissions.
