What is a Thermal Oxidizer?

Thermal oxidation is a process used, with wonderful outcomes, for the thermal oxidation of air streams containing risky natural pollution (VOCs). The thermal oxidation is carried out within a combustion chamber where the pollution inside the effluent to be handled are burned, generally decomposing them into carbon dioxide (CO2) and water vapor (H2O).

Thermal oxidation: types and working principles


The thermal oxidation process, because of high temperature, it’s proposed to remodel the harmful components into hurtless carbon dioxide (CO2) and water vapor (H2O).

There are several machines to realize thermal oxidation and the choice is based on several features such as the focus of the pollution to be handled and the extent of thermal efficiency to be obtained. The doable machines are:

Direct fired thermal Oxidizer:

It’s a thermal oxidizer without heat recovery. In observe it’s a suitable designed combustion chamber, https://www.tksindustrial.com/thermal-oxidizer-projects equipped with a burner, which thermally oxidized pollutants. On the finish of the chamber, we will insert completely different types of heat recovery based on the necessity of the shopper (often warmth recovery on thermal oil, water to provide steam or different heating recovery manufacturing).

Thermal recuperative Oxidizer:

It is a thermal oxidizer with heat exchanger. It is inbuilt such a approach that the effluent incoming is heated up from the flue gases in order to comprise the consumption of auxiliary fuel. Additional is feasible to utilize the residual warmth in the flue gases putting in a second warmth exchanger for air or for water as needed.

Regenerative thermal Oxidizer:

It’s a thermal oxidizer the place the heat exchanger for warmth recovery is regenerative type. A regenerative exchanger consisting of ceramic materials which, if suitably dimensioned, is able to achieve thermal recovery efficiencies up to ninety five%. The pollution, will be oxidized reaching the autothermal condition of the system, that means set to zero the auxiliary fuel consumption. Additionally in this case it’s attainable to install a final heat exchanger to the stack to recover once more on air or on water.

Catalytic thermal Oxidizer:

It’s a thermal oxidizer that makes use of a suitable catalyst for the oxidation of the pollutants that, in this means, can occur at decrease temperatures (about 300-four hundred ° C) sustaining comparable environmental efficiencies. To the system it is potential to combine a warmth exchanger to increase the heat recovery further limiting the auxiliary fuel consumption.

Only within the presence of halogenated compounds is feasible the formation of relative halogenated acid needing to insert in the purification process, downstream thermal oxidation, a wet abatement system through the use of our scrubber wetclean.

Thermal oxidizer strengths

ensures the highest abatement rate, exceeding that required by international requirements;

it’s offered in modular items that allow a rapid pre-meeting, minimizing the set up time at the set up site.

Available options

An heat exchanger could also be designed, in order to recover wise warmth from the output fumes. The wise warmth recovered in this way can be utilized to heat up air, water or diathermic oil, or can be utilized to obtain vapour.
