FLOW MODIFICATION DEVICES FOR REDUCING EMISSIONS FROM THERMAL VOC OXIDIZERS

摘要

A method and apparatus for reducing the emissions from a thermal oxidiser for volatile organic compounds (VOC) containing waste gases. The waste gas is treated in a thermal reactor and either before, in or after (1, 2, 3, 4) the thermal reactor the waste gas is contacted with a catalyzed surface device in the gas stream within the thermal oxidiser. The catalyzed surface device has a catalyzed surface which contacts the waste gas and further oxidizes the waste gas.
