System optimization and installation of GORE filter bags resulted in improvements to the baghouse and overall production process. Emissions from all the filters are well below 10 mg/Nm, maintenance on the filters has been significantly reduce, and extraction volumes from the furnaces have been significantly increased, leading to lower stack temperatures.

Test report prepared by Lectromec for Gore part number DXN2603. The report outlines Gore's compliance to ANSI/NEMA WC 27500 Test Methods for Environmental Testing, Jacket and Marking, as well as SAE AS4373 Test Method for Insulated Electric Wire.

High production levels and low pressure drop. Increased mill efficiency yielded considerable energy savings by producing a set tonnage in a much shorter period. The excellent cake-release characteristics enabled the collector to be operated continuously for 12 months at a maximum pressure drop of 5" w.g. The emission problem was eliminated.

Extraction at the furnace has increased above the design. The main fan damper is partially closed to control the extraction at the furnace. Tapping fume has been added into the same baghouse. The smelt house environment is much cooler, and it led to a decrease in maintenance of the electrode system and mechanical stokers.

Results showed furnace extraction has been increased by 41%, blockage was eliminated from furnace offtake ducts, hood temperatures were been reduced and stack emissions were below 5 mg/Nm3.

After the GORE Filter Bags were installed, bag life increased from one year to five years. Production downtime caused by the need to replace bags prematurely was virtually eliminated.
