Ceramic Fiber Hot Gas Filter Cartridge Filtration Solutions
Ceramic Fiber Cartridge · High-Temp Dust Removal · Acid Gas Resistance · Integrated TreatmentDesign a complete hot-gas filtration train around gas temperature, acid composition, dust loading, particle size, emission target and cleaning method—not around cartridge dimensions alone. Ceramic fiber media, optional catalytic coating, seals and mounting hardware must operate as one system.
What Our High-Temperature Flue Gas Clients Are Saying
High-temperature projects commonly fail through media degradation, acid-gas attack, unstable particulate emissions or excessive energy use. The first design step is to define the gas envelope and pollutant-control target for the complete collector.
“Acid vapor, fluorides and heavy-metal dust corrode conventional media and trigger excessive emissions.”
Severe Corrosion & Emission Pressure“Separate dust-removal and SCR systems occupy too much space and consume high electricity.”
Bulky Multi-Stage Equipment & High CostThree-Layer Solution for Ceramic Fiber Hot Gas Cartridges
The solution combines media selection for 200–900°C gas, a gradient porous cartridge for pulse-cleanable fine-particle capture, and matched frames and seals. Catalytic coating is evaluated when integrated NOx or dioxin treatment is required.
Precision Material Matching
We match ceramic media to 200–900°C gas, acid concentration and dust fineness; catalytic coating is available.
Gradient Porous Fiber Structure
Layered high-permeability pores deliver low resistance, pulse-cleaning performance and stable PM0.3 interception.
Complete One-Stop Supply
Standard or custom cartridges, mounting frames and seals are delivered as a complete assembly.
Cartridges for High-Temperature Flue Gas
Select the element family from the actual gas envelope: ceramic fiber for extreme-temperature particulate service, PPS needle felt for suitable medium-high-temperature humid gas, or cleanable sintered metal for rigid custom duties.
