An ideal solution for high solvent and variable operating conditions, CCS&ES direct fired thermal oxidizers, or afterburners, achieve >99% hydrocarbon destruction efficiency. Drawing polluted air streams into a turbulent and specially designed, heated, burner chamber, oxidizes the VOCs and HAPs in a safe, efficient manner. Yielding carbon dioxide and water vapor, the exhaust gas is now safe to enter the atmosphere, or an optional heat, recovery system. Providing safe operation, CCS&ES afterburners minimize risk of explosion and auxiliary fuel needs.
