ABSTRACT:
A continuous system and method for purging waste gases from dual heat exchange beds associated with a regenerative thermal oxidizer are disclosed. The system includes a purge recovery tank, a stack open to the atmosphere, a stack bypass, a stack valve in the stack, and a stack bypass valve in the stack bypass. The purge recovery tank is in fluid communication with two heat exchange beds, the stack, and the stack bypass. The stack is in fluid communication with the stack bypass and the heat exchange beds. A purge recycle control valve is used to recycle untreated waste gases from the purge recovery tank to the heat exchange beds and into the regenerative thermal oxidizer. A second embodiment wherein the purge recovery tank is positioned between the two heat exchange beds is also disclosed.
