Ceramic fiber filter tubes for hot gas filtration<\/figcaption><\/figure><\/div>

Anchor-Tech supplies rigid ceramic fiber filter tubes and complete hot gas filtration units that clean industrial exhaust at temperatures where bag filters and ESPs reach their limits. One vessel removes dust, acid gases, NOx and dioxins: particulate emissions stay below 5 mg\/Nm\u00b3<\/strong>, DeNOx efficiency exceeds 95%<\/strong> inside the SCR window, and filter grades cover continuous service at 600 \u00b0C and 1,000 \u00b0C<\/strong>.<\/p>

Plants running glass furnaces, incinerators, kilns and smelters face the same constraint: the gas that needs cleaning is hot, often corrosive, and carries fine PM2.5 and sub-micron particles. Cooling the gas first wastes recoverable heat and adds equipment. The three mainstream options compare as follows:<\/p>

Technology<\/th>Strengths<\/th>Limits in hot gas service<\/th><\/tr><\/thead>
Electrostatic precipitator (ESP)<\/td>Good collection efficiency; no secondary pollution<\/td>High energy consumption; performance swings with fuel and fly ash; large footprint; cannot hold ultra-low emission levels<\/td><\/tr>
Bag filter (fabric baghouse)<\/td>Good filtration; works with alkaline sorbent injection against acid gases<\/td>Not heat-resistant; hardens and ruptures in acid gas; short service life; mediocre PM2.5 capture; unstable ultra-low emission<\/td><\/tr>
Ceramic fiber filter (CF)<\/td>Very high filtration capacity; resistant to high temperature, acid and alkali; saves water and energy; long service life; no secondary pollution; stable ultra-low emission<\/td>\u2014<\/td><\/tr><\/tbody><\/table><\/div>

Ceramic filter tubes are rigid, self-supporting candles mounted on the tubesheet of a pulse-jet collector, exactly where filter bags would sit \u2014 which makes them a direct retrofit path for existing baghouses. \u2192 How to Retrofit a Baghouse to Ceramic Candle Filters<\/a><\/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

A CF hot gas filtration unit is more than a dust collector. With dry sorbent injection and catalyst-loaded filter tubes, a single vessel handles four pollutant groups:<\/p>
