A rotary valve thermal oxidizer including an interfacial seal disposed between rotating and fixed valve portions to prevent the mixing of treated and untreated gas streams. In a preferred embodiment, the valve sealing device includes a flowable sealing material contained within a receptacle, and contacted by a partition nested within the receptacle. Other sealing devices, as well as purge and/or sealing gases, may be employed to prevent leakage, while avoiding the use of machined parts.

Rotary valve thermal oxidizer

An improved structural support system for a regenerator used with a regenerative thermal oxidizer, including a perforated and corrugated rigid beam resting on a support surface. The perforated beam supports heat exchange materials either directly, or indirectly using a perforated grid. The beam includes a plurality of perforations permitting upward gas flow from the underside of the beam and through the heat exchange materials. The air distribution plenums under the beam are reduced in height from that of conventional systems. The novel structure results in a more reliable and efficient regenerator.
