RCO (Regenerative Catalytic Oxidizer):

The waste air discharged from the process which includes VOCs will enter into the double-groove RCO. The Poppet Valve will induce the waste air into the RTO’s Energy Recovery Chamber and preheat the waste air. The polluted waste air will be heated by the regenerative ceramic gradually and enter into the Catalyst Bed, where the VOCs will be oxidized by the catalyst decomposition and release heat to the 2nd Energy Recovery Chamber’s regenerative ceramic, used for reducing the consumption of the auxiliary fuel. The clean air from the heated, burnt and oxidized regenerative ceramic will reduce the temperature gradually, therefore, outlet temperature is slightly higher than the RCO inlet temperature. The Poppet Valve can be switched to change RCO’s inlet /outlet temperature. If the VOCs concentration is high enough and the released heat energy is enough, RCO doesn’t need fuel. For example, RCO heat recovery efficiency is 95%, RCO outlet temperature is only relatively 25 ℃higher than the inlet temperature.
