Brofind - Recuperative Thermal Oxidizers
Recuperative thermal oxidizers have an external or integrated thermal recovery section, coaxial with the combustion chamber for energy saving purposes.
The thermal recovery section preheats the air to be treated before entering the combustion chamber, at the same time cooling the outgoing purified air. A further heat recovery can be obtained downstream of the system, by exploiting the residual heat of the purified air to warm different services (air, diathermic oil, water, etc.) and further reduce managing costs.
- Electrical switchgear with PLC and remote assistance.
- Independent combustion system to guarantee correct operation of the plant.
- Modulating combustion system to maintain the correct operating temperature with different incoming pollutant loads.
- Combustion chamber refractory interior with high density ceramic fibre insulation, allowing the plant to last longer.
- High purification efficiency >99%.
- Thermal efficiency < 65% depending on the different applications.
- Reduced production of secondary pollutants (CO, NOx).
- Possibility of additional heat recovery.
- Easy to manage and use.
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.
