Lightweight Ceramic Filters for Coal Combustion,
Industrial Boilers, and Biomass Emissions
Containing Significant Submicron Particulate
Tri-Mer UltraTemp and UltraCat ceramic filter systems are 99%+ efficient for the collection of submicron particulate from sources including coal combustion, biomass combustion, industrial boilers, biomass boilers, and emissions from mixed fuels such as chicken litter, tires, and municipal solid waste. Tri-Mer ceramic filters can meet the 0.0011 lbs/MMBtu requirement for the Boiler MACT, as well as requirements for the CISWI MACT.
Advanced low-density ceramic filter systems can now remove PM, SO2, HCl, dioxins and even mercury in a single system. Particulate matter (PM) is removed to ultra-low levels (< 2 mg/Nm3, 0.001 grains/dscf), while other pollutants can be removed at percentages higher than 90%.
Ceramic filters, often called "candles" because of their solid tube shape, have been used in pollution control for decades. The original, high-density candle filters were manufactured from refractory grains such as alumina or silicon carbide and pressed into the basic candle shape – a tube with a closed rounded bottom and flange at the top. The newer, low-density filters start as a slurry of refractory fibers and are vacuum-formed into shape.
The UltraTemp and UltraCat systems offer significant advantages over conventional devices used for coal combustion, industrial boilers and biomass combustion emission sources. These include:
- Ability to handle hot gas streams, up to 1650°F
- Non-selective capture of particulate, including heavy metals
- Option to remove NOx at temperatures in the range of 350°F to 700°F
A second distictive feature of the ceramic filter systems is its ability to effectively remove gas pollutants that are generally treated with a wet scrubber or through high-temp Selective Catalytic Reduction (SCR.) These include SO2, HCl, HF as well as NO and NO2. The acid gases are removed through Dry Sorbent Injection (DSI), generally using sodium- based powders such as sodium bicarbonate and trona. Oxides of nitrogen are removed through injection of aqueous ammonia or urea upstream of UltraCat catalyst filters containing the embedded low-temp SCR catalyst.
The ceramic filters have proved effective on all types of particulate across the range of sizes, including submicron and ultrafine PM. Systems are manufactured to customer requirements in materials suited to the temperature of operation, including mild steel and stainless alloys. System sizes range from small to 100,000s of cfm.
