Recuperative thermal oxidizers, compared to direct thermal oxidizers, have a thermal recovery section downstream of the combustion chamber where the outgoing purified fumes preheat the incoming polluted air.
Based on the type of plant to be developed, the heat recovery section can be integrated and coaxial to the combustion chamber, or after and independent from it.
All solutions are just as efficient, only the process they are applied to changes.
These systems make it possible to reach thermal efficiency up to 65%, reducing the output of the installed burner and thereby decreasing the energy demand of the machine.
The sensitive heat of the fumes leaving the heat exchanger can be further recovered by installing a second exchanger, supplying additional heat for the customers, for example diathermic oil, water or simply air and to further reduce management costs.
These machines are often applied in the chemical, pharmaceutical, painting and waste processing industries and can be equipped with all the pre-and post treatment systems making them useful for the intended purpose.
