How to Find the Perfect Thermal Oxidizer Service?


Which Thermal Oxidizer Service Should You Choose?

A thermal oxidizer is a machine that incinerates dangerous pollutants at extremely high temperatures until the VOCs are eliminated, reducing air pollution and VOCs (Volatile Organic Compounds) from industrial exhaust airstreams.

These pollutants are hydrocarbon-based, which means they chemically oxidize into CO2, water vapor, and heat when they are destroyed by thermal oxidizers. A top-notch thermal oxidizer service can eliminate virtually all (99 percent) of air pollutants, HAPs, and VOCs due to their extremely high operating temperatures, allowing them to comply with tight pollution control requirements.

Time, Temperature, and Turbulence: The Three T’s

The performance of a thermal oxidizer is determined by three key factors: time, temperature, and turbulence. The three are intertwined and mutually reliant. The VOC destruction performance improves with increasing turbulence, temperature, or time. The thermal oxidizer’s objective is to oxidize hydrocarbons to produce water vapor and carbon dioxide.

The term “oxidation” is used to characterize this process. The breakdown of the bonds that make up a hydrocarbon molecule is referred to as oxidation. The molecule is broken apart into individual atoms when heated to the operational temperature and kept there for a long duration in a turbulent airstream. Water vapor and carbon dioxide are formed when these atoms recombine with oxygen in the air. After that, the clean airstream is securely released into the atmosphere. Once you track the right thermal oxidizer suppliers, you too can find a TO system that will work splendidly for your plant.


Thermal oxidizers heat contaminated air to temperatures between 1400 and 1800 degrees Fahrenheit (760 and 982 degrees Celsius) to achieve near-complete (99+ percent) elimination of contaminants.


The thermal oxidizer keeps the dirty airstream at high working temperatures for long enough to finish the oxidation. This period is referred to as “Dwell Time.” Over 99 percent of the VOCs are converted to carbon dioxide and water vapor after 0.5-1 seconds of dwell time.


Turbulence in the airstream ensures adequate mixing and heating of the airstream, allowing pollutants/VOCs to be completely oxidized.

What Are The Different Types Of Thermal Oxidizer Service Available?

thermal oxidizers manufacturersA Regenerative Thermal Oxidizer (RTO) eliminates pollutants such as Hazardous Air Pollutants (HAPs), Volatile Organic Compounds (VOCs), and odorous emissions that are frequently released by industrial processes.

In comparison to other thermal oxidizer technologies, regenerative thermal oxidizers achieve the best VOC abatement at the lowest operating cost and highest dependability. Regenerative thermal oxidizer manufacturers make sure that these systems make use of a unique heat recovery technology known as regeneration, which has proven to be the most cost-effective solution for oxidizers in normal industrial applications.

RTOs use heat sinks made of ceramic bits (media) to absorb and release heat. Heat is absorbed and released in regulated, recurrent cycles lasting around 2-4 minutes. When compared to other oxidizer technologies, this regenerative heat exchange has proven to be a particularly energy-efficient technique of oxidizing contaminants. In fact, if the process’s VOC concentration levels are larger than 3-4 percent LFL, RTOs can function with very little to no fuel.

Thermal Catalytic Oxidizers; Pollutants such as Hazardous Air Pollutants (HAPs), Volatile Organic Compounds (VOCs), and odorous emissions released during industrial processes are destroyed by a Catalytic Recuperative Oxidizer.

A catalytic oxidizer, like any other thermal oxidizer service, kills VOCs by heating polluted airstreams to high temperatures for a set amount of time. Catalytic systems are distinguished by the fact that they pass contaminated air over a catalyst material bed. When compared to thermal oxidizer systems, this catalyst material dramatically reduces the temperature required for oxidation. A catalytic oxidizer’s normal operating temperatures are 600-700F.

Recuperative thermal oxidizers are less thermally efficient than RTOs or catalytic oxidizers (they use more fuel). They are normally employed only in airstreams with high VOC concentrations or when a secondary heat exchanger for process heating is available. Due to the metal’s exposure to high temperatures, metal heat exchangers have a shorter life than regenerative thermal oxidizers and catalytic oxidizers.

A thermal oxidizer, like RTOs and catalytic oxidizers, exposes the dirty airstream to high temperatures to break the hydrocarbon bonds. By transferring the hot, clean exhaust gas via a primary and/or secondary non-contact heat exchanger, the heat required to raise the airstream temperature to the 1400-1500F operating temperature is recovered. The heat is transferred to the entering, unclean, chilly airstream to pre-heat it before it passes through the burner chamber to reach the ultimate working temperature, cleansing it before it passes through the heat exchanger and out to the atmosphere.

Thanks to the smart developments brought about by thermal oxidizer manufacturers, a single heat recovery device or many heat recovery devices can be used in a recuperative thermal oxidizer system.
