Regenerative thermal oxidizer (RTO) systems have proved themselves to be both cost-effective and highly efficient at controlling the emission of volatile organic compound or VOCs as well as hazardous air pollutants of HAPs. Specifically engineered to control each VOC emissions application, regenerative thermal oxidizers are ideal for applications that necessitate 80% recovery of heat.
In addition, other systems such as catalytic oxidizer systems are oftentimes not desirable as they can cause catalyst deactivation. RTO systems function using a thermal exchange cycle that periodically cools and heats shallow ceramic beds. VOC exhausts pass into the ceramic media which heats the exhaust almost to oxidation. The exhaust then enters a chamber where it is maintained at oxidation temperatures so that complete destruction can occur.
The clean gas then passes into another ceramic chamber where it is cooled and released. A third bed of ceramic is used to further purge the exhaust of VOCs. Regenerative thermal oxidizers boast many benefits making them the ideal choice. Heightened flow control through the system’s multiple heat exchange vessels, vertical flow which increases efficiency and lowers maintenance, as well as minimizing surges through the use of tandem valves are all ways in which RTOs are more effective and cost efficient.
Regenerative thermal oxidizers also utilize high temperatures in order to incinerate dangerous volatile organic compounds and a third ceramic bed to thoroughly remove all VOCs. Their ability to work with both single as well as multiple sources of emission is yet another reason to choose regenerative thermal oxidizer systems.
