At this rail-to-barge trans-loading facility on the Ohio River, a set of six stacker tubes connected by conveyors allows the stockpiling of coal. Coal would hang up inside the tubes, sticking to the walls, building up inside.
To clean coal out of the tubes, the operation resorted to manual labor. A man-lift would be used to raise personnel to the lowest window of a stacker tube, so they could dig out the accumulated coal. This proved expensive, as it consumed six to eight hours of labor, and it exposed personnel to a safety hazard working on the stockpiles and inside the tubes.
Plant management wanted to remove the accumulated material and completely empty the stacker tubes. As a test, two Martin® Air Cannons were installed to clean out material from the Number 2 Stacker Tube.
The air cannons were installed on the catwalk of the tower. The discharge air from the air cannons is piped down more than 70 feet (21m) to the top of the tube’s lowest windows, to remove blockages from the discharge opening.
The first discharge of the air cannons on the Number 2 Stacker Tube removed approximately 50 tons of coal built up inside. The trial installation was so successful that within a week of its completion, Kanawha River Terminal ordered ten more air cannons—two for each of the remaining five stacker tubes.
