In recent years, regenerative thermal oxidizer (RTO) has become one of the main technology for processing industrial organic waste gas. The production of nitrogen oxides and the content of volatile organic compounds (VOCs) in the exhaust gas are reduced by using hightemperature air combustion technology, which can effectively solve the problem of air pollution. The development history and main application fields of regenerative combustion technology were summarized. The two important reference indexes of regenerative combustion technology, namely pressure drop and thermal efficiency, were analyzed. As an important part of RTO, the material density, shape and size of the regenerative thermal oxidation incinerator will directly affect the amount of VOCs emissions and NOx production. Ceramic composite is the common regenerator material. The influences of LanteCombH, 40×40 hole honeycomb ceramic, 25 mm moment saddle ring and MLM180 sheet composite honeycomb ceramic heat accumulator on the pressure drop and thermal efficiency of RTO equipment were mainly analyzed. The results show that LanteCombH has the advantages of small pressure drop and high thermal efficiency. It was proposed that optimizing the structure of regenerator to solve the potential safety hazards during the operation of RTO equipment was the focus of future research.
