High Temperature Ceramic Fiber Filter Tube, Corrosion Resistant Ceramic Filter Candle for Industrial Incinerator Flue Gas Dust Removal
This high temperature ceramic fiber filter tube is integrally sintered with high-purity alumina and silicon carbide composite ceramic fiber. Different from traditional filter bags and metal filter cartridges, it can withstand flue gas up to 800°C for long-term continuous operation, featuring acid & alkali resistance, oxidation resistance and thermal shock resistance. It acts as the core filter element for high-temperature flue gas dust removal in hazardous waste incineration, municipal waste incineration, metallurgy, carbon industry and chemical plants. With uniform porous structure, its dust removal efficiency reaches ≥99.9%, which effectively intercepts ultra-fine dust, tar and acid flue gas particles. It eliminates the risk of filter bag burnout and has a far longer service life than PTFE and fiberglass filter bags, compatible with pulse backblowing, reverse air and negative pressure dust collectors.

The eight key advantages of the product.
- Ultra-high temperature resistance & zero burnout risk: Fully inorganic ceramic material runs stably under 800°C, safe for open-flame flue gas of municipal solid waste and hazardous waste incinerators;
- Superior chemical corrosion resistance: Resist erosion of HCl, SO₂, HF acid and alkali metal dust, suitable for highly corrosive chemical and solid waste incineration flue gas;
- Excellent thermal stability: No cracking under rapid cold-hot alternation, stable service life under frequent furnace startup & shutdown;
- High-precision filtration for ultra-fine dust: Submicron pores capture tar, fly ash and heavy metal particles to meet exhaust emission standards;
- Self-support rigid structure without deformation: No cage required, high tube wall rigidity, no collapse or deformation under high-pressure backblowing;
- Low operation & maintenance cost with long replacement cycle: 70% less replacement frequency compared with high-temperature filter bags, greatly reducing downtime maintenance labor cost;
- Optional waterproof & oil-proof coating: Coated version avoids tube clogging under high humidity and high tar flue gas, extending ash cleaning interval;
- Full customized size service: Outer diameter, length, end cap structure and flange size can be non-standard produced according to dust collector drawings.

FAQ
How to choose between ceramic fiber filter tubes and high-temperature PTFE filter bags?
Choose ceramic filter tube preferentially if flue gas temperature＞260℃, with acid corrosion or frequent overtemperature conditions; PTFE filter bag is available for medium-low temperature clean flue gas with limited budget.
Do the filter tubes support customization of non-standard sizes?
Outer diameter, total length, end cap and flange are all customizable, compatible with all kinds of imported and domestic high-temperature dust collectors worldwide.
Will ceramic filter tubes crack or shatter easily?
Integrally sintered under high temperature with strong toughness and thermal shock resistance, no cracking under standard furnace startup and shutdown, much better than ordinary ceramic parts.
