Handling tons of PRB coal, a plant was having problems with dust and spillage at their conveyor transfer points. This material loss was costing the plant money in the form of decreased productivity, potential regulatory agency fines, and the cost of man hours to clean it up.

Fire-protection guidelines for: Conveyors transporting coal

accumulation, preventing spills and conducting effective regular clean up. For example, float dust should be contained within transfer points, and spillage from belts must be minimized. Conveyors should never be stopped and allowed to stand with an un-discharged load for an extended period. The accumulation of coal below a conveyor provides fire fuel and can even result in spontaneous ignition

Coal Spillage Significantly Reduced By Martin® Transfer

All coal burned at the plant moves through a single chute. The path is at an angle of roughly 90 degrees from either of the discharging conveyors, making for a difficult transfer. A drop height of 30 feet also creates problems, including a large flow of induced air, resulting in dust escape, high levels of impact leading to idler damage and belt abrasion from poor control of the flow of coal.
