Recent regulations, as well as a general aversion to central dust collectors within the Powder River Basin Coal user's community, have created a need for an alternate method for eliminating airborne dust. This paper addresses the capital expenditure as well as the cost of ownership of an integrated point source air cleaning system in comparison to a central collection system. This assessment was conducted by comparing the cost to purchase and operate a central dust collection system and integrated air cleaner system on a typical multiple transfer point application. The central dust collector consists of a negative pressure blower, a series of filter bags, a collection hopper, a screw conveyor to place collected material back into the material stream, and a series of ducts to pull air and dust from individual pickup points. The point specific integrated air cleaners consists of a negative pressure blower to pull dust and air from an application point through a bag-less filter media located at the application point. The agglomerated material is then redeposited into the material stream at point of use without the need for ducting or a central material hopper. The assessment yielded a 54% reduction in capital expenditure and a 26% reduction in operating costs for the same application when using individual dust filters as opposed to a central system. In addition to the lowered cost, there are reductions in risk associated with the elimination of ductwork and the central containment enclosure for collected explosive dust. By the conclusion of this paper, the reader will have a better understanding of the quantifiable differences between a central dust collection system and a set integrated air cleaner systems.

Plant management had a mission: to make the Midwestern 646-megawatt power plant a leader in the clean and safe handling of PRB coal. To accomplish that goal, the organization embarked on an ambitious five-year plan to upgrade the plant's coal handling system. The plant improved its conveyor transfer points, and installed new dust management systems, controlling dust and spillage, and improving plant safety and efficiency. This presentation will discuss the initial surveys that led to the development of the 5-year plan, and the resulting project priorities, the problem areas, application points identified, and the various technologies applied. Included in the goals for the upgraded systems installed were the elimination of spillage through the improvement of transfer points on coal-handling conveyors using improved belt support and sealing systems. In addition, new air cleaners were installed at seven loading zones, and a foam dust-suppression system added at one location to provide dust management throughout the plant's coal handling system. These new dust control systems allowed the plant to eliminate its older central dust collection system that had greater risks of explosions. A continued series of monthly inspection and service visits by conveyor maintenance technicians helps continue the coal handling system's high levels of performance. This five-year plan helped the power plant take "great leap forward" in controlling dust and spillage from handling PRB coal. Copyright © 2013 by ASME.

Hibbing Public Utilities (HPU), providing electricity to the city of Hibbing (MN), USA, has formed a joint company with Virginia Public Utilities, called Laurentian Energy to deliver power from the abundant biomass resources nearby. Under a 20-year contract with Xcel Energy, the firm currently produces about 300000 megawatt hours of electricity per year, approximately 70 per cent of it from biomass. Electric brush cleaners were installed on each conveyor as they are very effective on the type of belts used at this facility. The transfer chutes employ special geometries that capture and concentrate the material stream as it travels through. Martin Engineering's Apron Seal Skirting provides two wear surfaces on a single elastomer sealing strip, installed along the bottom of the skirtboard.

Asked to summarize the experience overall, Price-Stephens said, "We were pleased by the level of support that we received from Martin Engineering, without having to hound anyone. And we were impressed by the fact that when we did the initial start-up, it was the guys who helped design the equipment who were there to oversee the start-up. "To some extent, I think bulk terminals like ours have learned to live with a certain amount of spillage and dust, believing that it's unavoidable," he added. "We've proven here that isn't the case. When you look at the components and see what's been designed for this facility, you realize the concepts and technology are pretty straightforward. It's really about simple things done well.

It sometimes occurs that the conveying of bulk solid materials via belt conveyor poses a significant problem due to the conveyed material's characteristics. The following article presents one such case, and the solutions found to solve the problem.

Fugitive material has been an issue in bulk material handling for as long as conveyors have been in use. Dust and spillage create a variety of potential hazards and waste valuable resources. Consequences of regulatory violations can range from simple warnings to massive fines. A proactive approach is to eliminate the root cause, typically through the use of dust collectors to gather and filter dust-laden air. An alternative to the common central dust collector is the integrated air cleaner, which eliminates the need for large, complex air handling systems in favor of smaller, independently operating units at the dust generation points. Specifying an air cleaning system requires quantifying cost and power usage to develop a systematic evaluation of the options. In many cases, the integrated approach is superior to central designs, with lower capital investment and reduced cost of ownership.

Stark Excavating, a Ready-Mix Concrete plant in the Midwestern United States has resolved material build-up issues in three storage silos where accumulation had slowed production and increased internal pressures, eventually damaging the vessel walls and forcing a shutdown. The company contacted Martin Engineering, which provided a heavy duty whip. The Martin heavy duty whip is a portable, remote-controlled tool that can be lowered into storage containers through a manhole opening. Powered by compressed air, the patented motor can use a variety of different flails and cutting edges to knock down accumulated material without damaging storage vessels. Martin's top-access cleaning technology eliminates the need to send a man inside a storage vessel and risk potential injury. The equipment is set up outside the silo, and it's portable enough to maneuver around various bin sizes and shapes. The silo restoration will include removing all internal horizontal supports, pulling all sidewalls back to their origin.

Eagle Materials Illinois Cement facility experienced a serious blockage in its 80000 ton storage silo, and so it employed an innovative pneumatic cleaning technology from Martin Engineering that was remote controlled from outside the domed structure. Powered by compressed air, the Martin Heavy Duty Whip's patented gyro motor can use a variety of flails and cutting edges to knock down accumulated material without damaging storage vessels. Abrasion-resistant steel chain is best suited for most applications, with non-sparking brass chain for combustible materials. Urethane flails can also be employed to protect lined vessels that could be susceptible to damage from metal tools. The equipment can be set up quickly outside the vessel, and it's portable enough to move easily around various bin sizes and shapes. In most cases, the technique allows material to be recaptured and returned to the material stream. With the Whip, capacity of the plant increased to 1.1 million short tons, while the cost structure was reduced by 20%.

The unscheduled shutdowns at the Büyükçekmece cement plant, Istanbul, interfered with production and exposed the staff to potential hazards. Upon completion of the audit, it was determined that a series of air cannons would be the best option to return normal flow to the system and prevent future blockages. The two basic components of an air cannon are a fast-acting, high-flow valve and a pressure vessel (tank). The device performs work when compressed air in the tank is suddenly released by the valve and directed through a nozzle, which is strategically positioned in the tower, duct, cyclone or other location. The air blasts help break down material accumulations and clear blocked pathways, allowing solids and/or gases to resume normal flow. The installation included hi-velocity and fan-jet nozzles with Martin thermo safety shields to protect maintenance personnel when they inspect or service the air cannon system.
