Design Of Thermal Oxidizers For Industrial Air Pollution Control

A Thermal oxidizer, also known as a thermal incinerator or combustion chamber, is an industrial air pollution control device that uses high temperatures to combust hazardous air pollutants (HAPs) and volatile organic compounds (VOCs) emitted from industrial processes into inert gases, water vapor, and carbon dioxide. To design an effective thermal oxidizer, several design criteria need to be considered. The first is the type of pollutant to be treated and its concentration. This will determine the size of the oxidizer and the temperature required for efficient combustion. The second criterion is the airflow rate, which needs to be optimized for complete combustion of the pollutants. The third factor to consider is the residence time, as the amount of time the pollutants remain in the high-temperature environment affects the efficiency of combustion. The fourth criterion is the heat recovery system, which can help recover heat generated during combustion and reduce fuel usage. Finally, the material selection for the oxidizer must be carefully made to withstand high temperatures, thermal shock, and chemical resistance. In summary, an effective thermal oxidation system requires consideration of the pollutant type and concentration, airflow rate, residence time, heat recovery system, and material selection.
