Air Control Science®, Inc. Coal Dust Containment Technology Earns Best Available Control Technology Designation in Wyoming
Wyoming Selects Dustless Transfer® Technology for
Ability to Reduce Fugitive Dust
BOULDER, Colo., February 7, 2005 – Air Control Science, Inc., (ACS) a leading engineering, procurement and construction (EPC) firm specializing in dust and fume control in coal-fired power and primary metals, announced that its Dustless Transfer technology has earned Best Available Control Technology from the Wyoming Department of Environmental Quality, a designation bestowed for the Dustless Transfer’s ability to reduce fugitive coal dust emissions at the Wyodak Power Plant in Gillette, Wyo.
Best Available Control Technology designation is determined after an exhaustive review of whether a new technology – in this case the ACS Dustless Transfer technology – can replace an existing technology because it produces better emissions control outcomes. At the Wyodak Power Plant, after the Dustless Transfer technology was installed, emission dust levels were reduced 24 percent, 16 percent, and 59 percent, respectively, at three test locations. In fact, by incorporating the Dustless Transfer, Wyodak will be able to eventually remove enormous dust collection baghouses that were installed when the plant was constructed in 1978.
“Receiving Best Available Control Technology is a significant accomplishment for our company and for Wyodak officials, who made every effort to find the best technology for reducing dust emissions,” said John S. Fischer, Chairman and CEO of Air Control Science. “As the entity holding the permit for this plant upgrade, Wyodak officials had to undertake all the effort and post-installation testing to make this designation reality.”
Air Control Science’s Dustless Transfer technology is a passive dust control system that includes:
• A hood to direct and consolidate the off-loading stream of bulk material (typically coal) to minimize air induction into the enclosure
• A “spoon” to receive this consolidated stream and settle it on the receiving conveyor belt at the proper speed and direction, resulting in less dust generation, air turbulence and belt wear
• Primary and secondary stilling chambers to lower internal air velocities, allowing dust to settle and remain with the material stream
• Curtains throughout and at the end of the secondary stilling chamber to lower internal air velocities and keep the dust with the material stream rather than becoming airborne.
Now applied in many power plant environments, the Dustless Transfer is proving to be an excellent solution for controlling hard to handle material such as Powder River Basin coal, a coal mined throughout Wyoming and Montana. This low-sulfur, sub-bituminous PRB coal is known for its low cost, but also for its dusty, exothermic properties leading to spontaneous combustion. The Dustless Transfer technology has lowered dust emissions in the workspace from 30 mg/m3 to ambient dust readings as low as 0.08 mg/m3 running 1400 tons/hour of PRB coal.
“If this coal is not contained at transfer points, it builds up on walls, floors, and bunkers throughout plants, creating an unhealthy and dangerous environment for workers and secondarily jeopardizes valuable plant equipment,” Mr. Fischer said.
ACS has many innovative systems and proprietary technologies that make bulk materials handling cleaner, safer and more productive. These include:
• Smart Chute™, a technology program used to ensure smooth coal flow;
• Glider Roller Belt Support® system, proprietary technology that provides a flat, near friction-free foundation in conveyor transfer points to reduce spillage and airborne dust;
• Dust Analyst® rational analysis, a precise method for determining airflow requirements in dust control systems.
These leading technologies enhance facilities’ assets by reducing equipment wear and keep workers safe by controlling the escape of fugitive dust and spillage.
