Thermal Oxidizers block in a straight channel perp perpendicular to the cold face. The advantage of this design face o is that it theoretically provides a straight, aerodynamic channel for the air stream. The disadvantage is that if particulate plugs a channel at the cold face, where the inflow enters the block, then this entire channel becomes a dead zone. Corrugated structured packing. The most advanced ceramic heat exchange media for RTOs is corrugated structured packing. Ceramic structured packing is constructed of corrugated sheets of ceramic. The angle of inclination of the corrugations of adjacent sheets is reversed, ensuring excellent distribution of airflow throughout the media bed. Even if an area of the media bed became plugged by particulate, the mixing and spreading effect of the alternating corrugation prevents down zones above the plugged area. Field studies have shown that, upon installation, RTOs with corrugated structured packing consume the same amount of natural gas as RTOs with monolith-structured block, although the former has superior airflow distribution, and the latter has slightly higher heat storage capacity. The advantage of the corrugated solution becomes dramatic over time because of its ability to resist fouling caused by particulate buildup.

Lifetime operation costs Owners of thermal oxidizers have a number of options available when installing a new system or replacing the media bed of an existing system. VOC abatement systems in the finishing industry, where particulates can be a concern, are prime examples of a applications that should consider corrugated structured packing. This solution may cost more to purchase and install, but it will provide lower pressure drop, higher heat transfer efficiency, more reliable operation, and longer useful life compared to the alternative media. The significant long-term reduction in energy consumption alone can far outweigh the additional cost of installing advanced heat exchange media.
