The regenerative combustion plant is based on the concept of achieving a high thermal energy recovery with the aid of large ceramic masses that – during the heat recovery phase – absorb the heat from combustion gases and – during the regeneration phase – release the accumulated heat for the pre-heating of inlet polluted air. The residual fraction of unrecovered thermal energy is partially, or totally, supplied by the heat generated by the combustion of solvents dissolved into the polluted air.

The advantage of catalytic combustion, when compared to the thermal one, is to guarantee the complete oxidation of volatile organic substances at relatively low temperatures, usually 320-450°C. The low combustion temperature, as well as allowing less energy consumption, ensures a negligible production of NOx, a pollutant thet in combustors operating at higher temperatures is usually present in concentrations as high as the higher limits permitted by current regulations.
