Thermal oxidizer equipment lessens hazardous pollutants

Recently many plants have referred to the thermal oxidizer service that became an integral part of the whole process. Apparently thermal oxidizers have been approved by many environmentalists, because they became a great way to reduce air pollution caused by hazardous air pollutants (HAPs). Thermal oxidizer equipment basically makes a great many industrial processes less harmful for the environment.

The operating principle is based on high-temperature thermal oxidation. Emitted dense exhaust gases get into the thermal oxidizer, where a chemical reaction takes place. These hazardous particles react with oxygen at a high temperature, which converts them into non-hazardous emissions like carbon dioxide (CO2), heat and water vapor. Therefore this reaction is known as a thermal oxidation.

There are four different types of thermal oxidizers, and they differ in their basic operating principle. So they are regenerative thermal oxidizers (RTO), direct flame oxidizers (they use flames), non-flame oxidizers (instead of flames they use slow heating to burn pollutants) and recuperative thermal oxidizers. One can choose a thermal oxidizer according to his preferences and finances.

Regenerative thermal oxidizers, unlike recuperative ones, regenerate up to 95% of energy proceeded from the oxidation process. Harmless emissions are released to the environment through ceramic heat transfer platforms, which lowers operating costs. RTO consists of heat exchange media, system fan, burner, motor, PLC based system controls, temperature recorder, flow control valves and exhaust stack. Recuperative thermal oxidizers act like heat exchangers; they transfer heat from the outtake air stream to the intake air stream.

To sum up, thermal oxidizer equipment destroys process gases containing Volatile Organic Compounds (VOCs) and Hazardous Air Pollutants (HAPs) converting them into innocuous emissions – water vapor, heat and CO2 (carbon dioxide).

There’s a lot of information on the Internet about thermal ozidizers of all types. You can also purchase one online.
