Abstract
A smoke abatement assembly is provided as an adjunct overlaying a cooking device such as a broiler or fryer system in a commercial restaurant. The smoke abatement assembly comprises a sealed housing which supports a low-pressure flame arrester, between 1 and 10 inches above the cooking area of the cooking device. A catalyst module is also removably mounted within the sealed housing above the flame arrester. The module includes a plurality of spaced low-pressure oxidation catalysts of controlled thickness, between 1 and 6 inches thick. The plurality of catalysts have a combined thickness equal to the thickness of a single catalyst providing the optimum catalyst volume or contact time for the installation. Each of the components, that is the flame arrester and plurality of catalysts, defines a smoke access area substantially equal to the cooking area of the broiler or fryer. A preheater can be provided to maintain the temperature at the catalysts at an optimum range during idle conditions when no cooking is occurring.
