ABSTRACT:
An emission control system for an asphalt kettle combines a number of features to increase efficiency and convenience of operation, while minimizing potential safety hazards. The asphalt kettle is connected via a duct to a separate afterburner device equipped with a fan. This fan pulls fumes from a hood of the kettle through the duct to the afterburner device. The fan then pushes the fumes into a combustion chamber housed in the afterburner device. The combustion chamber includes an air port having an outlet proximate to the burner for furnishing a supply of fresh air to the flame to prevent its being extinguished by the rapid movement of gas through the combustion chamber. The afterburner device may include a one-way valve that prevents backdraft of ignited fumes from the combustion chamber into the kettle due to negative pressure within the kettle. The afterburner device may also include a temperature sensor that shuts down the fan in the event of kettle ignition.
