The rotary RTO, or rotary regenerative thermal oxidizer, functions by oxidizing combustible exhaust air into oxides and water at high temperatures, effectively purifying the exhaust and recycling the heat released during decomposition. It achieves a decomposition efficiency exceeding 99.5% and a heat recovery efficiency of over 97%. The system consists of a combustion chamber, ceramic packing bed, and rotary valve, divided into 12 chambers: five for inlet, five for outlet, one for cleaning, and one for isolation. The exhaust gas distribution valve, driven by a motor, rotates continuously and uniformly, allowing the exhaust gas to switch smoothly between the chambers.

For high concentrations of exhaust air, an additional exchanger can be configured to convert it into fuel, with heat recovery options including hot air, hot water, steam, and oil. This square rotary valve RTO is suitable for VOCs treatment across various industries, known for its compact design, stable operation, and high efficiency. It can process between 5,000 m³/h and 100,000 m³/h and has proven successful in industries like printing, film coating, and chemicals, earning positive feedback from customers.

How does a Regenerative Thermal Oxidizer Work?

Regenerative Thermal Oxidizers function by eliminating volatile organic compounds (VOCs) from exhaust streams through high-temperature oxidation—efficiently breaking them down into carbon dioxide and water vapor at operating temperatures of approximately 800°C. A key feature of this system is its use of a single, continuously rotating distribution valve, which replaces the conventional array of poppet valves. This innovative valve configuration partitions a cylindrical heat storage bed horizontally into several independent sectors, thereby streamlining the gas flow management.

As this valve gradually rotates, each sector cyclically performs distinct functions: preheating the incoming polluted gas, recovering and storing thermal energy from the cleaned effluent, and undergoing a purging process. This smooth, uninterrupted rotation ensures seamless transitions between operational stages, significantly reducing pressure fluctuations commonly encountered in traditional valve-switching systems.

The process begins when contaminated gas enters through the rotary valve and moves through preheated ceramic sectors, raising its temperature before it enters the combustion chamber. There, natural gas and combustion air are introduced to sustain the high temperature necessary for complete oxidation. Following treatment, the purified gas passes through cooler ceramic zones, transferring heat to the media and enabling highly efficient thermal recovery. A small stream of cleaned gas is also diverted to purge residual pollutants, preventing untreated gas leakage, while specialized sealing mechanisms ensure gas tightness between adjacent process streams. Altogether, this continuous rotary design not only boosts operational reliability and thermal performance but also reduces maintenance demands compared to older system architectures.
