Abstract
A filter utilizes a filter bed having a ceramic media to remove particulates from process emissions upstream of a regenerative incinerator to prevent fouling of the incinerator. To prevent the filter from fouling, the filter is adapted to 'bake-off' contaminants from the filter bed by providing a flow of hot innocuous air through the filter. In addition, fluid can be flushed through the filter.
