Ceramic Catalyst Filter controls PM Emissions. This Particulate Control System is ideal where there is PM2.5, submicron particulate, and high temperatures.

Particulate Control / PM Emissions

The typical level of PM emissions at the outlet of the ceramic filters is less than 0.001 grains/dscf (2.0 mg/Nm3). This is true even with very heavy inlet loadings of several thousand milligrams per cubic meter. Good for PM10, PM2.5 and submicron PM (PM1.0).

PM emissions are captured on the face of the filter tubes and does not penetrate deeply into the filter body, thus allowing for repetitive and complete cleaning. This is an engineered feature of the ceramic filter surface. Only over five to ten years does the pressure drop very gradually increase to the point that filters are changed for energy reasons. Pressure drop for the new clean filter is 3 - 4 inches w.g. Pressure drop can be lowered by adding more filter elements or footprint, and capital cost can be reduced by decreasing the filter count at the expense of fan horsepower.

The filter construction also means that standard reverse pulse jet methods, which send a pulse of compressed air down the center of the tube, can thoroughly clean the accumulated PM from the outer surface of the tube. Filters are cleaned on-line, with no need to isolate each housing plenum.

Typical ceramic filter life is 5 to 10 years. The filters are effective across the range of particle sizes, but are most often used when there is a large fraction of PM2.5 and submicron particulate and / or high temperatures.

Ceramic filter elements have the same efficiency as fabric filter bags but can withstand much higher temperatures, have a much longer life, and can also remove NOx, CO, Dioxins and Organic HAPs.

Particulate Control Filter PM 2.5

Reverse Pulse Jet Cleaning

Ceramic filters compared to fabric bags:

  • Can also be configured to remove SO2, SO3, HCI, HF and Mercury
  • Can withstand and operate at much higher temperatures
  • Can remove NOx, CO
  • Can also remove dioxins, O-HAPS in the CEMENT-NESHAP
  • Same PM efficiency, same "air to cloth" ratio
