Abstract: A method for processing an air stream using a thermal oxidizer, by pre-heating the air stream, without the use of auxiliary heat, and substantially eliminating the condensation of organic or inorganic compounds within the air stream to be treated. Alternatively, or in combination, the system used for this pre-heat method can also be used to accommodate intermittent higher volumes of organic or inorganic compounds without the need for additional bypass hardware or any unnecessary waste of energy or capital costs.

Abstract: 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.
