Thermal oxidation is a process used, with excellent outcomes, for the thermal oxidation of air streams containing unstable organic pollution (VOCs). The thermal oxidation is carried out within a combustion chamber where the pollutants inside the effluent to be treated are burned, typically decomposing them into carbon dioxide (CO2) and water vapor (H2O).
Thermal oxidation: types and https://www.tksindustrial.com/thermal-oxidizer-projects working ideas
The thermal oxidation process, attributable to high temperature, it is proposed to transform the harmful parts into hurtless carbon dioxide (CO2) and water vapor (H2O).
There are several machines to realize thermal oxidation and the selection is predicated on a number of facets such as the focus of the pollution to be handled and the level of thermal efficiency to be obtained. The potential machines are:
Direct fired thermal Oxidizer:
It is a thermal oxidizer with out warmth recovery. In follow it is a suitable designed combustion chamber, outfitted with a burner, which thermally oxidized pollutants. On the end of the chamber, we are able to insert totally different types of heat recovery based mostly on the need of the client (often heat recovery on thermal oil, water to supply steam or other heating recovery production).
Thermal recuperative Oxidizer:
It’s a thermal oxidizer with warmth exchanger. It is in-built such a method that the effluent incoming is heated up from the flue gases so as to contain the consumption of auxiliary fuel. Further is possible to make the most of the residual heat in the flue gases installing a second warmth exchanger for air or for water as needed.
Regenerative thermal Oxidizer:
It is a thermal oxidizer where the warmth exchanger for heat recovery is regenerative type. A regenerative exchanger consisting of ceramic materials which, if suitably dimensioned, is able to reach thermal recovery efficiencies as much as 95%. The pollution, might be oxidized reaching the autothermal condition of the system, that means set to zero the auxiliary fuel consumption. Additionally in this case it is doable to put in a ultimate warmth exchanger to the stack to recover again 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 happen at lower temperatures (about 300-400 ° C) maintaining comparable environmental efficiencies. To the system it’s potential to mix a warmth exchanger to extend the heat recovery additional limiting the auxiliary fuel consumption.
Only within the presence of halogenated compounds is feasible the formation of relative halogenated acid needing to insert within the purification process, downstream thermal oxidation, a wet abatement system by the usage of our scrubber wetclean.
Thermal oxidizer strengths
ensures the highest abatement rate, exceeding that required by worldwide standards;
it is offered in modular units that permit a speedy pre-meeting, minimizing the installation time on the set up site.
An warmth exchanger could also be designed, in an effort to recover wise warmth from the output fumes. The wise heat recovered in this method can be utilized to warmth up air, water or diathermic oil, or can be used to obtain vapour.
