Regenerative Oxidation
The contaminated air is first drawn in by the process air fan and heated to the required reaction temperature by a gas burner. The pollutants are then converted into carbon dioxide and water in the combined reactor and heat storage bed. The waste heat from the reactor is routed through a second bed and stored there. After the storage bed has been heated, the process air flow is switched. The stored heat is used to preheat the process gas stream, and the pollutants are then oxidized in the first bed. During further operation, the system cycles between these states.
Low energy costs due to high thermal efficiency • Robust system design • Long service life • Proven technology • Versatile application • Automatic adaptation to changing operating conditions • Catalytic operation possible (RKNV) • Reliable compliance with exhaust air standards
Due to its robustness, the system technology can also be used for complex exhaust air streams contaminated with impurities (e.g., organosilicon compounds).
