The system destroys VOCs by ducting the solvent-laden process exhaust through a heat exchanger, where the air is preheated. The air then passes through a combustion chamber, which raises the air temperature further. After that, the exhaust flows into a chamber containing a catalyst, where high temperature ignition destroys the VOCs. Use of a catalyst allows VOCs to be destroyed at lower temperatures, which decreases the amount of fuel required to heat the exhaust stream, and consequently reduces operating costs. To further reduce fuel consumption, an air-to-air exhaust preheat heat exchanger is used to transfer some of the heat from the clean air leaving the system to the incoming solvent-laden air. The system can operate effectively on waste air streams that contain relatively low concentrations of VOCs.
The oxidizer uses stainless steel extensively to provide heavy service without corrosion. The combustion and catalyst chambers as well as the ductwork are thoroughly insulated for high-energy efficiency. The control system is housed in a NEMA enclosure, which can be located wherever the customer requires for easy operator interface. The oxidizer is skid-mounted, and shipped pre-wired and pre-piped to facilitate quick installation.
