All Resources For Filter Bags for the Waste-to-Energy Industry

Overview

Waste-to-energy plants provide a sustainable solution to the global problem of waste disposal, efficiently producing heat and electricity. But with incineration comes a handful of harmful particulates and pollutants — including dioxins, NOx, SO2, CO and mercury — and plants must follow strict regulations for emissions control.

At the same time, plants need to control costs.

GORE Filter Bags help waste-to-energy plants reliably control air emissions and improve their bottom line with solutions to control particulate emissions and pollution. Our PTFE membrane-based filter bags

  • reliably capture particulates to ensure near-zero emissions
  • deliver long bag life and stability, resulting in a lower cost of ownership
  • minimize resistance to airflow, allowing for efficient waste processing and steam production

As the original inventor of membrane-based industrial filtration solutions, we continually push the envelope of innovation in the waste-to-energy industry. As a result, we’ve developed a suite of high-performance filter bags that address the industry’s and our customers’ needs. Across our solutions, reliability is the Gore standard — as is the long product life our customers have come to expect.

Innovative Products for the waste-to-energy market

When analyzing Gore’s products for use in your filtration systems, we encourage you to consider 3 important factors:

  • our truly innovative products which offer filtration performance that you will not find elsewhere
  • our proven product reliability and
  • our unique system approach to filtration process optimization, which includes our technical support for the lifetime of the filter bags

These three attributes enable Gore’s solutions to deliver the lowest total cost of ownership available in a filtration system.

GORE® REMEDIA® Catalytic Filter Bags for Dioxin/Furan Destruction

The GORE REMEDIA Catalytic Filter Bags are installed in some of the world’s largest incinerators to simultaneously provide dust control and destroy up to 99% of gaseous dioxins and furans. Here's how GORE REMEDIA Filter Bags work:

The unique GORE™ membrane captures fine particulate on the surface of the filter. As the filter bag is cleaned, solids are released from the surface and collected in the bottom of the baghouse hopper. The gaseous dioxins and furans pass through the GORE membrane into the catalytic felt, which converts them into insignificant amounts of CO2, H2O and HCl. This approach is maintenance-free and has been proven across hundreds of cases worldwide.

GORE REMEDIA Membrane Technology

GORE REMEDIA Filter Bags combine the principles of surface filtration and catalysis.

GORE® DeNOx Catalytic Filter Bags: for Reduction of NOx, NH3 and other Vapor Phase Pollutants

Our latest development in catalytic filtration is GORE DeNOx Catalytic Filter Bags, specifically designed to reduce NOx and NH3. This technology works in a similar way to GORE REMEDIA Filter Bags, but requires the presence of NH3 to react with NOx. Our filter bags contain a high efficiency catalyst and essentially perform the same function as an SCR tower — except GORE DeNOx Catalytic Filter Bags are installed inside your existing baghouse, requiring minimal process changes, additional equipment or worker training, at a significant cost savings to you.

This two-bag filter system includes an outer-layer ePTFE membrane filter bag for particulate removal, plus an inner layer catalyst filter bag, allowing maximum flexibility for catalyst regeneration and long product life.

The two-bag DeNOx system reduces NOx and NH3

The two-bag DeNOx system reduces NOx and NH3. It’s easy to install and requires minimal process changes.

GORE® Low Emission Filter Bags for superior particulate emission control

The new GORE Low Emission Filter Bags are seam-taped to prevent any leaks through the stitch holes, allowing them to meet the strictest emission regulations while providing the same level of quality and reliability as our standard filter bags. The key to the bags is the patented PTFE seam tape, which is resistant to cracks despite high temperatures, mechanical stress and chemical exposure.

GORE Low Emission Filter Bags

GORE Low Emission Filter Bags are seam-sealed for the utmost in emissions control.

These filter bags are commonly used in:

  • flue gas cleaning of waste incineration
  • biomass-to-energy power plants in primary filters
  • dry and semidry sorption systems
  • end-of-pipe filters

Reliability

For more than 30 years, we’ve earned a reputation for reliability in waste-to-energy plants around the world. Our customers count on us in the most challenging applications where failure is not an option. Our products work as intended the first time, and consistently every time.

But our value doesn’t stop there. We consistently develop innovative, high-performance filtration products that meet our high standards for reliability.

Why are our filters so reliably effective? It starts with the proprietary PTFE membrane in each of our filters. Gore was the original inventor of membrane-based filters for industrial filtration, which enabled an industry-wide change in filtration performance due to their superior cleanability and particulate capture. The PTFE membranes in our filters simultaneously capture the most miniscule particulates while allowing a high rate of airflow.

Membrane comparison
Compare Low Drag Membrane with Standard Membrane

Our ePTFE membrane is a very thin, porous layer that prevents particulate matter from entering the body of the filter bag. Without the ePTFE membrane, particulate matter will penetrate the conventional filter, making it weaker and more resistant to airflow, especially over time.

Additionally, our proprietary PTFE membrane is:

  • chemically inert
  • resistant to extreme temperatures
  • hydrophobic
  • mechanically tough

These qualities, along with Gore’s sewing design and construction, make our filters reliably durable, leading to long product life. Time and again, Gore filters are proven to last longer than our competitors’ filters — and longer bag life leads to lower maintenance costs, increased yield and greater productivity.

Whether you use standard or low-grade coals, wood or tires in your furnace, or operate a municipal, hazardous or medical waste incinerator, longer bag life means lower overall cost of ownership for you. Our filters are proven to operate with less pressure drop, requiring less energy for manufacturers to power them — and this can also lower your cost of ownership.

Bottom line: Once your GORE Filter Bags are installed, you can rely on them to work as intended — during the first production cycle and long after installation.

What Do Filter Bags Cost?

Our filter bags deliver the filtration industry’s lowest available total cost of ownership, which goes beyond the price of filter bags to consider what your filtration system will cost you over time. Several factors impact the total cost of ownership for a baghouse, including:

  • duration of product life
  • costs of maintenance and cleaning
  • energy cost of fans that move air through a baghouse
  • purchase price of filter bags
  • labor cost to install filter bags

GORE Filter Bags deliver exceptional value. With your bags, you get a cutting-edge membrane laminate, robust filter bag design and construction, a system approach optimized for your baghouse and technical support for the life of your filter bags — along with the reliability our customers come to expect from Gore. With these factors combined, we provide the lowest total cost of ownership available in a filtration system.
