Development of Regenerative Thermal Oxidizer Technology
Principle of Regenerative Oxidation Boiler Technology
The Regenerative Thermal Oxidizer (RTO) boiler can "store" the heat generated from waste gas combustion and subsequently output high-temperature flue gas. It achieves a heat conversion efficiency of up to 99% and a comprehensive thermal efficiency exceeding 97%. It enables highly efficient regenerative utilization of the thermal energy carried by the waste gas.

Intelligent Safety System
Addressing the high coupling of system parameters, we have developed a real-time optimization control program with multiple constraints, enabling the entire system to operate safely under optimal conditions. A Hazard and Operability (HAZOP) study specific to the operating conditions is conducted for each system, ensuring "absolute reliability and fail-safe operation!"
