Utilizing either catalytic or non-catalytic ceramic filters, the systems are able to achieve the regulatory emission limits both now and into the future. The system, while operating similarly to a baghouse, offers much greater flexibility in application due to a similar temperature resistance of 450°C for catalytic, and up to 1000°C for non-catalytic. These filters are capable of efficiently removing NOx, dust, SOx and other acid gases simultaneously with a single piece of equipment at high temperature. The system offers flexibility and modularity for adjusting to whatever may arise in the future.
