Thermal oxidizers are pollution control devices used to reduce harmful emissions from industrial processes. They work by heating volatile organic compounds (VOCs) and other pollutants to high temperatures, typically between 1,400°F and 2,000°F. This process converts the pollutants into harmless gases, primarily carbon dioxide and water vapor, thereby improving air quality. These systems are commonly used in industries such as chemical manufacturing, printing, and automotive to manage emissions. Thermal oxidizers can be designed as direct or indirect systems, depending on the specific needs of the facility and the type of pollutants being treated.
