Damper Technologies for Regenerative Thermal Oxidizers

By Anu Vij, Pro-Environmental |

    Regenerative thermal oxidizers (RTOs) are commonly used for controlling volatile organic compound (VOC) emissions from a broad spectrum of industries. An RTO is basically a thermal oxidizer that uses ceramic media as the heat exchanger medium, providing high heat recoveries. Over the past few years, much attention has been given to the pros and cons of the different types of ceramic media used in an RTO system. Little, however, has been written about other critical aspects of the RTO system, such as dampers and burners. This article offers a primer on the damper technologies. BACKGROUND The purpose of valves (or dampers) in an RTO system is to provide tight shut-off of process air in order to maintain destruction and removal efficiency (DRE) and proper heat exchanger operation (thermal energy recovery or TER). Valves serve not only to regulate the flow of air, but also to isolate ducting and equipment for maintenance. Proper valve design is critical for high VOC destruction efficiency over a long equipment life. Cycling more than 400,000 times a year, RTO valves must operate reliably, and must seal to less than 0.25% leakage at full system pressure. To prevent distortion and misalignment for sealing surfaces, valve designs…
