A variety of auxiliary pollution control approaches are currently available. This is a brief discussion of the different types, comparing some of the features, benefits and potential drawbacks of each. When this occurs, an exothermic reaction occurs and heat is released. Oxidizers typically are designed with 0.5 seconds or greater total residence time. Residence time is critical, not for the oxidation reaction, but for proper mixing.
Many designs fail to complete the mixing in the time available.
NOx output should be considered because it is a primary component in the production of ozone. These systems utilize a ceramic stoneware or other heat exchange media. In most designs, the media is mounted in vertical columns. The process air stream is passed through a column of media as it enters the oxidizer. The air stream is subsequently heated further to oxidation temperatures by a burner in the central combustion chamber.
