Application Note
Overview:

Thermal oxidizers, also known as fume incinerators or afterburners, are widely used to control air emissions. Many processes, such as paint baking, drying of printing inks and curing of certain polymers, evolve vapors of flammable, toxic solvents. In the baking or curing oven, these solvent vapors pose an explosion or fire hazard, so they are diluted well below their lower limit of flammability by adding large amounts of dilution air.
