A leader in dust control solutions has helped a port located along the Hudson River control fugitive particle emissions using atomised mist technology.

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.

“Our goal was to improve air quality for the safety of our employees and the surrounding community,” said Stephen Kelly, vice president of sales and business development at the Port of Coeymans.

Flexible solution

One machine at the port 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.

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 arrive at the port per year arrive from Greece, Turkey, Egypt and Spain, delivering nearly 33,000 tonnes (30,000 metric tonnes) per week of clinker.

The DB-60 has a specially designed barrel with a powerful fan on the back end and a circular manifold with 30 atomising spray nozzles on the front. The fan forces air through the cannon and past the manifold, launching millions of tiny atomised mist droplets 50 to 200 microns in size.

By introducing droplets roughly the same size as the dust particles, the droplets are able to travel with the particles, collide with them and drag them to the ground before they drift onto the dock area or across the site line.

A 25 HP fan producing 30,000 CFM (849.50 CMM) of air flow propels the engineered mist in a 200 foot (60 metre) long cone that reaches high over the deck of the ship.

Operators report that air quality at the port has significantly improved during the unloading of clinker and other dusty materials and that fugitive dust emissions have not been seen leaving the site since adding the units to the facility’s dust management plan.

The industrial park has experienced a noticeable improvement in air quality, especially when a DB-60 is in operation during dry and windy periods.
