What 300+ Installations Taught Us About Application Fit<\/h3>\n

Since 2008 we have commissioned ceramic filtration systems in cement, glass, waste-to-energy, biomass, metallurgy, and chemical plants across more than 30 countries. The single biggest lesson: the filter element is rarely the problem \u2014 the gas conditions around it are. Plants that share their real operating data (temperature curves, ash chemistry, cleaning cycles) during the design phase routinely achieve 10-year tube life. Plants that size on nameplate conditions alone tend to call us about premature blinding or thermal shock within two years. That is why every application review we do starts with your process data, not our catalog.<\/p>\n<\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

The Same Comparison in Text: Conventional Bag-Filter Train vs. Ceramic Fiber Filtration<\/h3>

The flow diagrams above are summarized below in text form, so the two process routes can be compared at a glance.<\/p>

Process route<\/h4>
Conventional train (cyclone + cooling + drying + bag filter)<\/th>Ceramic fiber filter system<\/th><\/tr><\/thead>
Dusty gas → Cyclone dust precipitator → Cooling → Drying → Bag filter → Chimney emissions<\/td>Dusty gas → Ceramic fiber filter filtration system → Heat recovery → Chimney emissions<\/td><\/tr><\/tbody><\/table><\/div>

Where the conventional train falls short<\/h4>
  • Cyclone dust precipitator:<\/strong> prone to abrasion, and it cannot remove dust on its own.<\/li>
  • Cooling stage:<\/strong> heat energy cannot be recovered directly and is wasted; additional investment in cooling equipment is required.<\/li>
  • Bag filter:<\/strong> service life of only about one year; cannot withstand high temperatures; burns in case of fire; no resistance to acid and alkali corrosion.<\/li><\/ul>

    What the ceramic fiber filter system delivers<\/h4>
    • Service life of up to 10 years<\/li>
    • Operating temperature up to 1,100 °C<\/li>
    • Filtration efficiency up to 99.99%<\/li>
    • Acid and alkali corrosion resistance<\/li><\/ul>

      Advantages of the system<\/h4>
      1. High dedusting efficiency<\/li>
      2. Simple overall structure that needs only a few supporting devices<\/li>
      3. Long service life<\/li>
      4. Extremely low operating and maintenance costs<\/li>

        The advantages of the non-catalyst ceramic fiber filter of the dedusting system<\/strong>:<\/strong><\/h3>

        1,The maximum long-term service temperature of this ceramic fiber filter is up to1100\u2103. There is no need to cool the gas, nor cooperate with cyclone dust precipitator during operation. The gas cleanliness after this filtration process is much higher than the national emission requirement..<\/p>

        2,As there is no need to install cyclone dust precipitators, cooling systems and other equipment, the overall area of the system is greatly reduced, and the initial redundant equipment investment and subsequent operation and maintenance costs are saved..<\/p>

        3,The ceramic fiber filter is several times long lasting than the traditional bag filter. Generally, the ceramic fiber filter can be used for 5-10 years (10 years of service life is very common), while the traditional bag filter can be used for only 1 year. That means the ceramic filter can not only help to save the costs of replacing the filter material, but also avoid system shutdown and the loss caused by it..<\/p>

        4,The heat energy in the gas can be recovered directly by using the dedusting system of the ceramic fiber filter.<\/p>

        5,The filtration efficiency of the dedusting system with ceramic fiber filter can be as high as 99.9%, and the filtration effect is very good..<\/p>

        6,The ceramic fiber filter is resistant to acid and alkali corrosion, while the traditional bag filter is not.<\/p>

        7,The ceramic fiber filter is very stable in chemical properties, and it is difficult for other chemicals to react with it.<\/p>

        8,The ceramic fiber has thermal shock resistance, and the physical properties of the filter will not be destroyed by the rapid change of the temperature.<\/p>

        9,The ceramic fiber filter is very hard itself, so there is no need to use keel support like the traditional bag filter. This reduce the abrasion risk between the keel and the bag.<\/p>

        10,Its way of use and the backflush cleaning method is similar to the traditional bag filter. That means it is easy to design and install for the company with the traditional bag filter design experience.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

        The Same Comparison in Text: Conventional Desulfurization & Denitrification Trains vs. Integrated Ceramic Fiber Filtration<\/h3>

        The three process routes shown above are summarized below in text form.<\/p>

        Route 1 — SCR + electrostatic precipitator + wet desulfurization<\/h4>

        Boiler gas → SCR denitrification (urea\/ammonia injection) → Electrostatic precipitator → Wet desulfurization → Chimney emissions<\/p>

        • SCR denitrification:<\/strong> dust accumulation; dust blocking the honeycomb ceramics; catalysts poisoned by heavy metals; catalyst failure; declining denitrification efficiency; rising ammonia slip.<\/li>
        • Electrostatic precipitator:<\/strong> high technical threshold; expensive equipment; cannot be maintained in-house; high power consumption.<\/li>
        • Wet desulfurization:<\/strong> sewage generation; waste gypsum treatment; high water consumption; equipment prone to corrosion; high power consumption.<\/li><\/ul>

          Route 2 — Electrostatic precipitator + SCR + semi-dry desulfurization<\/h4>

          Boiler gas → Electrostatic precipitator → SCR denitrification (urea\/ammonia injection) → Semi-dry desulfurization → Chimney emissions<\/p>

          • Electrostatic precipitator:<\/strong> high technical threshold; expensive equipment; cannot be maintained in-house; high power consumption.<\/li>
          • SCR denitrification:<\/strong> ABS (ammonium bisulfate) blockage; catalysts poisoned by heavy metals; catalyst failure; declining denitrification efficiency; rising ammonia slip.<\/li>
          • Semi-dry desulfurization:<\/strong> requires water spraying to cool the gas; must be combined with a bag filter for dedusting; secondary dedusting; the dust cake falls off completely during backflushing; low dedusting efficiency; short filter material service life.<\/li><\/ul>

            Route 3 — Integrated ceramic fiber filter filtration system<\/h4>

            Boiler gas → Ceramic fiber filter filtration system (with slaked lime \/ sodium hydroxide and urea\/ammonia injection) → Waste heat recovery → Chimney emissions<\/p>

            • Efficient dedusting, desulfurization and denitrification in a single unit<\/li>
            • Low maintenance cost<\/li>
            • Long filter material service life and mature technology<\/li>
            • Efficient heat recovery, reduced corrosion and clean gas<\/li><\/ul>

              Advantages of the integrated system<\/h4>
              1. Simple, integrated system that performs dedusting, desulfurization and denitrification simultaneously<\/li>
              2. Avoids catalyst poisoning and blocked honeycomb ceramics<\/li>
              3. Reduces the ABS (ammonium bisulfate) problem<\/li>
              4. Efficient heat energy recovery<\/li>
              5. No sewage generated<\/li><\/ol>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

                The advantages of the catalytic ceramic fiber filter of the dedusting system<\/strong>:<\/strong><\/h3>

                1,The desulfurization efficiency can be as high as 95%. The sulfur-containing gas undergoes two desulfurization processes in the system.<\/p>

                2,Dry desulfurization is used in this system, so there is no sewage generated. This omits the sewage treatment and other steps.<\/p>

                3,It solves the problem of large water consumption and power consumption during wet dedusting.<\/p>

                4,The denitrification efficiency can be up to 95%, far exceeding the national standards.<\/p>

                5,It solves the problems that the dust is easy to block the honeycomb ceramics, the catalyst is to be poisoned, and denitrification efficiency is decreased during SCR denitrification.<\/p>

                6,It can remove dioxin directly and efficiently, which solve the problems that the process is hard to control and there are many subsequent treatment procedures when activated carbon is used to absorb the dioxins.<\/p>

                7,The system can be designed as an integrated gas purification system with functions of de-dusting, desulfurization, denitrification, de-acid gas and de-dioxin simultaneously. It can also be deleted some functions according to demand.<\/p>

                8,Because of the reduction of treatment steps and the equipment quantity and volume, the ceramic fiber filter system is more centralized and compact. Its area occupied is only 1\/3 of the traditional flue gas treatment system.<\/p>

                9,There is no need to install electrostatic precipitation (ESP), which solve the problems of high technical threshold, large power consumption, and difficult maintenance of electrostatic precipitation (ESP) system.<\/p>

                10,It has better economic benefits and can save about 25-35% of the overall cost.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
