The Enclosed Ground Flare destroys a waste stream, but does not maintain a constant temperature while doing so, simplifying the control scheme, and allowing the overall system to be more economical. These systems allow for reduced flame visibility, minimal heat and noise, real-time emissions sampling, and smokeless combustion. These flares may require supplemental assist gas streams depending on whether the process stream can sustain combustion. by ensuring proper residence time, Fully Enclosed Ground Flares attain relatively high destruction efficiencies.
Regenerative Thermal Oxidizers (RTO) are waste gas incinerators that employ multiple beds of ceramic media that absorb heat from the exhaust gas and use this captured heat to preheat the incoming process streams. RTO’s are often used in applications such as at paint booths, printing mills, and paper mills which produce low VOC concentrations in relatively higher flow rates. This technology eliminates these streams in a highly efficient and cost effective manner while minimizing the need for fuel gas. Moreover, they can acheive ~99% destruction efficiency with 95% heat recovery.
