Comparison of Various Combustion Methods
There are four major combustion methods to treat VOCs: Direct Flame Incinerator (DFI), Regenerative Thermal Oxidizer (RTO), Catalytic Combustion System (CCS・CATox・CO) and more recently Regenerative Catalytic Oxidizer (RCO).
Among them, the CCS and the RCO methods (by catalytic oxidation) allow to avoid the formation of thermal NOx and CO gases and provide a high-level VOCs destruction while efficiently eliminating inconvenient smells.
