Pollution Control

Thermal Barriers & High-Temperature Products for Pollution Control Equipment

Pollution control equipment operates in demanding thermal environments. Thermal oxidizers, regenerative thermal oxidizers (RTOs), catalytic oxidizers, scrubbers, filtration systems, ductwork, and exhaust equipment can experience elevated temperatures, thermal cycling, vibration, particulate exposure, and continuous operation.

Sealing and thermal protection components help control heat, accommodate equipment movement, and maintain system performance. Gaskets, Inc. manufactures custom high-temperature products for pollution control equipment, including tadpole seals, expansion joints, flexible ducting, rope gaskets, and thermal barrier materials.

With more than 65 years of thermal sealing experience, we understand that the right component depends on more than temperature alone. Seal geometry, compression, movement, surface condition, and installation all factor into long-term performance.

Industry Challenges

Pollution control systems handle process gases and emissions under conditions that can be hard on sealing components. Repeated heating and cooling can create expansion and contraction, while particulate, vibration, and chemical exposure can contribute to wear.

Common challenges include:

  • Elevated operating temperatures
  • Repeated thermal cycling
  • Thermal expansion and contraction
  • Abrasive dust, ash, and particulate
  • Chemical and corrosive environments
  • Air leakage and heat loss
  • Equipment vibration
  • Uneven sealing surfaces
  • Continuous operation
  • Scheduled maintenance outages

Selecting the appropriate material and seal configuration can help reduce heat loss, accommodate movement, and extend service life.

Sealing Solutions for Pollution Control Equipment

Pollution control equipment varies considerably in design and operating conditions. Gaskets, Inc. works with OEMs, engineers, contractors, and maintenance teams to manufacture components around the requirements of the equipment.

Products commonly used in pollution control applications include:

  • Fabric Expansion Joints
  • Tadpole Seals
  • Fiberglass Rope Gaskets
  • Ceramic Rope Gaskets
  • High-Temperature Tapes
  • Flexible Ducting
  • Extruded Silicone Seals
  • High-Temperature Materials
  • Custom-Fabricated Thermal Barriers

Tadpole seals are commonly used around access doors, inspection points, dampers, and other areas requiring a compressible thermal seal. Different cover materials, core constructions, bulb sizes, and tail dimensions allow the seal to be configured for the application.

Expansion joints and flexible ducting can accommodate thermal movement, vibration, and equipment misalignment in ductwork and exhaust systems.

Thermal Oxidizer & RTO Applications

Thermal oxidizers and regenerative thermal oxidizers operate at elevated temperatures and undergo repeated thermal cycles. Those conditions can place significant demands on seals around access doors, inspection panels, dampers, ducts, and other equipment joints.

Gaskets, Inc. manufactures tadpole seals, expansion joints, flexible ducting, rope gaskets, and thermal barrier materials for these applications. Seal construction can be selected based on operating temperature, movement, available compression, and the physical characteristics of the sealing surface.

For RTO systems in particular, repeated cycling makes compression recovery and material durability important considerations when selecting a seal.

Catalytic Oxidizer & Fume Incinerator Applications

Catalytic oxidizers and fume incinerators also require sealing components capable of operating around elevated-temperature process gases. Gaskets, Inc. manufactures tadpole seals and other high-temperature components for doors, access panels, ducts, dampers, and other sealing points.

Where thermal expansion, vibration, or equipment movement is a concern, flexible ducting and expansion joints can provide the movement capability needed to maintain the connection.

Common Applications

Gaskets, Inc. products are commonly used in pollution control and emissions-control equipment, including:

  • Thermal oxidizers
  • Regenerative thermal oxidizers (RTOs)
  • Catalytic oxidizers
  • Fume incinerators
  • Emissions control systems
  • SCR catalyst systems
  • Oxidation catalyst systems
  • Baghouse systems
  • Dust collection systems
  • Wet and dry scrubbers
  • Industrial ductwork
  • Exhaust systems
  • Exhaust silencers
  • Access doors
  • Inspection hatches
  • Dampers
  • Heat recovery equipment

The appropriate sealing approach depends on the equipment and location. Tadpole seals can provide compressible thermal sealing around doors and panels, while rope gaskets may be appropriate for flexible packing applications. Expansion joints and flexible ducting address movement in ductwork and exhaust systems.

Managing Heat, Movement & Air Leakage

A relatively small sealing gap can have a meaningful effect on a larger pollution control system. Heat loss and air leakage around doors, access panels, ducts, and expansion areas can increase operating demands and contribute to maintenance issues.

The right seal needs to maintain compression while accommodating the movement created by changing temperatures. In high-cycle applications, compression recovery and material durability become especially important.

Gaskets, Inc. can work from drawings, dimensions, samples, or existing specifications when developing a replacement or custom component.

Supporting Reliable Pollution Control Equipment

Pollution control systems are often critical to a larger industrial process. When a seal, expansion joint, or flexible connection needs to be replaced, the component needs to fit the equipment and perform under its actual operating conditions.

Gaskets, Inc. manufactures custom thermal sealing products for pollution control equipment, from tadpole seals and rope gaskets to expansion joints, flexible ducting, and high-temperature thermal barriers.
