The system is used to clean the exhaust air from solvents and other pollutants (ex. CO) through thermal oxidation; it is also possible to recover the exceeding heat coming from the combustion of the pollutants.
The system uses an heat exchanger Air/Air to preheat the polluted air by means of the waste heat of the depurated flow, that has been oxidized in the combustion chamber by using a support burner.
The purified flow coming out from the combustion chamber, before entering in the preheating exchanger of the polluted air, usually pass through a recovery boiler where, as example of use, is heated the thermal oil used in production. The purified air is released in the atmosphere trough a suitable stack/chimney.
Typical applications: Solvent processing industry suitable only for high solvent concentration
