Exhaust Gas Incinerator (Continuous RTO)
Product Introduction: This continuous regenerative thermal oxidizer (RTO) is designed to treat, through high-temperature, harmless incineration, orderly-discharged, high-concentration, toxic, hazardous, and malodorous organic exhaust gases generated during industrial production processes. Thanks to the company’s patented continuous heat exchange (regenerative) technology, this RTO offers superior stability compared with conventional RTOs during continuous production operations, while also reducing energy consumption in the original production process. The process principle involves a regenerative high-temperature exhaust gas incinerator that treats exhaust gases produced during coating baking operations—gases that contain a certain concentration and temperature—and directs them into a multi-stage heat exchanger for preheating (regenerative heat storage).

Product Introduction
This continuous regenerative thermal oxidizer (RTO) is designed to treat, through high-temperature incineration for harmless destruction, orderly-discharged, high-concentration, toxic, hazardous, and malodorous organic waste gases generated during process production. By employing the company’s patented continuous heat-exchange (regenerative) technology—patent no. ZL 2012 1 0023570.3—the system offers superior stability compared with conventional RTOs during continuous process operations, while simultaneously reducing energy consumption in the original production process.
Process Principle
A regenerative high-temperature waste-gas incinerator is employed to treat the waste gases generated during the coating-baking process, which contain a certain concentration and temperature of pollutants. These waste gases are first fed into a multi-stage heat-exchanger for regenerative preheating (R), raising their temperature to a level suitable for entry into the incinerator chamber. Inside the furnace, a large-ratio-modulation burner precisely controls the combustion temperature within the range of 720°C to 750°C (T), ensuring complete thermal cracking (oxidation, O) and combustion of the harmful organic compounds in the waste gases. The heat produced during combustion is partially used for heating purposes and partially for preheating the waste gases and supplementing fresh air (regenerative preheating), thus sustaining a continuous, cyclical operation. Incineration chamber temperature, furnace negative pressure, waste-gas flow rate (and concentration), and waste-gas oxygen content are carefully controlled to ensure safe operation of the incinerator; meanwhile, the supply-air temperature and the main air-distribution-pipe pressure are maintained at constant levels to guarantee stable operation of the centralized heating system.

Performance Features
● High purification efficiency: Uniform collection, mixing, and air distribution of exhaust gases, coupled with thorough heat exchange (regenerative heat storage) and stable temperature control, significantly enhance purification efficiency to ≥99.5%, meeting the Class I environmental emission standards of Shanghai, Beijing, and Guangzhou.
● Significant energy-saving performance: The thermal energy generated during high-temperature incineration is recovered and recycled, with user testimonials—particularly in the tinplate printing industry—demonstrating energy savings of 15% to 35%.
● Excellent safety: The furnace is equipped with an explosion-proof door to relieve detonation pressure, and employs staged, slightly negative-pressure combustion, which effectively prevents backfire.
● High degree of automation: Fully replaces the original oven temperature control, requiring only a single button press to start and operating entirely automatically throughout the entire process. Equipped with safety protection features such as over-temperature and low-temperature alarms, as well as flame-out alarms, to ensure stable operation of the equipment.
