Thermal oxidation is a process used, with excellent outcomes, for the thermal oxidation of air streams containing risky natural pollution (VOCs). The thermal oxidation is carried out within a combustion chamber the place 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, as a result of high temperature, it’s proposed to rework the dangerous components into hurtless carbon dioxide (CO2) and water vapor (H2O).
There are a number of machines to realize thermal oxidation and the selection is based on a number of elements such as the concentration of the pollution to be handled and the level of thermal effectivity to be obtained. The potential machines are:
Direct fired thermal Oxidizer:
It’s a thermal oxidizer with out warmth recovery. In follow it’s a suitable designed combustion chamber, equipped with a burner, which thermally oxidized pollutants. At the end of the chamber, we will insert totally different types of heat recovery based on the necessity of the client (often warmth recovery on thermal oil, water to provide steam or other heating recovery production).
Thermal recuperative Oxidizer:
It is a thermal oxidizer with heat exchanger. It is in-built such a way that the effluent incoming is heated up from the flue gases with a purpose to comprise the consumption of auxiliary fuel. Additional is possible to utilize the residual warmth in the flue gases installing a second warmth exchanger for air or for water as needed.
Regenerative thermal Oxidizer:
It’s a thermal oxidizer where the heat exchanger for https://www.tksindustrial.com/thermal-oxidizer-projects heat recovery is regenerative type. A regenerative exchanger consisting of ceramic materials which, if suitably dimensioned, is able to achieve thermal recovery efficiencies up to 95%. The pollution, can be oxidized reaching the autothermal situation of the system, that means set to zero the auxiliary fuel consumption. Also 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 pollution that, in this method, can happen at lower temperatures (about 300-four hundred ° C) maintaining comparable environmental efficiencies. To the system it is attainable to mix a heat exchanger to extend the heat recovery further limiting the auxiliary fuel consumption.
Only within the presence of halogenated compounds is possible the formation of relative halogenated acid needing to insert within the purification process, downstream thermal oxidation, a moist abatement system by means of using our scrubber wetclean.
Thermal oxidizer strengths
ensures the highest abatement rate, exceeding that required by worldwide requirements;
it is offered in modular models that permit a speedy pre-meeting, minimizing the set up time on the installation site.
An heat exchanger could also be designed, as a way to recover smart heat from the output fumes. The smart heat recovered in this means can be utilized to heat up air, water or diathermic oil, or can be utilized to obtain vapour.
