VOCs Treatment by Incinerator

Direct Oxidizers The direct thermal oxidizers represent the simplest plants of the oxidizers group: in them, the polluted air is conveyed in a combustion chamber where, thanks to one or more burners, a temperature of 720-950°C is maintained to allow the proper pollutants combustion and the complete flow purification.

Regenerative Thermal Oxidizers Regenerative thermal oxidizers (RTO) are machines equipped with ceramic mass regenerative heat exchangers which allow for a high thermal efficiency thanks to their capability of quickly accumulating and yielding heat. This characteristic of theirs makes it possible to implement plants which yield up to 96%. The high heat recovery implemented by the correct sizing of the ceramic exchanger allow the plant to be self-sufficient, namely switching off the burner, which entails nullifying machine fuel consumption. The calorific value of the pollutant (VOC) present in the stream which burns in the combustion chamber therefore maintains the combustion temperature. Regenerative thermal oxidizers are configured based on their specific application and can be grouped as follows:

These machines are generally applied for all of those VOC laden emissions with 2-3 g/Nm3 or more to exploit self-sufficiency. Whereas for lower concentrations, they are the only system capable of minimising the operating cost of the machine due to the high heat recovery.
