Abstract:
A method for processing one or more air streams containing pollutants using a thermal oxidizer employing a heat exchanger section and an oxidation chamber, said air streams having a preselected range of pollutant concentration, said air streams also having intermittent concentration of pollutants higher than said preselected range of pollutant concentration, the method comprising the steps of:mixing ambient air with a heated air stream from the oxidation chamber to form an intermediate air stream;mixing the intermediate air stream with an inlet process stream prior to directing the resulting air stream into the thermal oxidizer, wherein the resulting air stream is heated to a temperature sufficient to substantially eliminate the condensation of organic or inorganic compounds within it; and;when the inlet process stream has a concentration of pollutants higher than said preselected range of pollutant concentration mixing a greater volume of the intermediate air stream with the inlet process stream, wherein the resulting air stream decreases the thermal efficiency of the heat exchanger portion of the thermal oxidizer.
