RTOの仕組み
RTO uses a ceramic bed heated from the previous oxidation cycle to preheat the input gases to partially oxidize them. The preheated gas enters the combustion chamber, which is heated by an external fuel source to reach the target oxidation temperature between 760°C (1,400 °F) そして 820°C (1,510 °F). For applications requiring maximum damage, the final temperature may be as high as 1,100 °C (2,010 °F).
Versatile & Highly Efficient
RTO is versatile and highly efficient – up to 95% thermal efficiency. They are often used to reduce solvents, fumes, odors, etc. from all walks of life. RTO regenerative thermal oxidizers are ideal for low to high VOC concentration ranges up to 10 g/m³ solvents.
Superior Destruction Efficiency
There are many types of regenerative thermal oxidizers on the market today that have a volatile organic compound (VOC) oxidation or destruction efficiency of 99.5+%. The ceramic heat exchanger in the tower can be designed for thermal efficiency of up to 97+%.

再生熱酸化装置とは？
再生熱酸化物（RTO）は、排出ガスを（破壊）排出ガスに変換し、熱を利用して排出ガスをCO2とH2Oに変換して大気中に放出することにより、揮発性有機化合物（VOC）、有害大気汚染物質（HAP）、悪臭を制御する燃焼装置である。RTOは最大97%の熱効率と99%以上の破壊効率を達成できる。
RTO oxidant is considered one of the most advanced thermal oxidation systems in the world. Compared to other thermal oxidizers, regenerative thermal oxidizers (RTOS) have a thermal efficiency of up to 97%, and destruction efficiency may exceed 99%, which will give you the highest removal rate at the lowest life cycle cost. -- Matched with industry-leading structures and design features, all deliver superior performance, significantly lower operating costs, and industry-leading reliability.
How Does a Regenerative Thermal Oxidizer 仕事？
Pushing air filled with pollutants through the peroxide, usually with a system fan.
あ valve directs airflow into one of two heat exchangers (ceramic dielectric bed).
Dirty air absorbs heat from the hot ceramic medium and enters the combustion chamber.
At >1500°F for >5 seconds, VOCs and HAP oxidize into CO₂ and H₂O.
Hot clean air enters the second ceramic bed to absorb heat for reuse.
Cooled clean air is discharged into the atmosphere.
The valve changes direction every few minutes, reversing the flow so heat transfer alternates between the two ceramic media beds. This is why RTO (regenerative thermal oxidizers) have high fuel efficiency and low operating costs, making them an ideal VOC reduction system.

RTO Rotary Distribution Valve — Core Structure Explained
Complete technical breakdown of the rotary valve assembly, optimization structures, and performance validation
Overall Structure
The rotary distribution valve consists of six major components: valve body, central rotating shaft, partitioned valve disc, drive actuator mechanism, multi-layer sealing assembly, and cooling system. The motor drives the valve core to rotate, periodically switching the intake, exhaust, and purge chambers to achieve the RTO regenerative heat exchange cycle.
Three Key Optimization Structures
The rotary valve incorporates three critical design innovations that significantly extend service life and improve operational stability under extreme thermal cycling conditions.
Precision Clearance Structure
Shaft sleeves, valve plates, and bearings are designed with graded assembly clearances to offset metal thermal expansion at high temperatures, preventing shaft seizure and valve plate jamming.
Forced Air Cooling System
The valve body features a circumferential air-cooling flow channel. Ambient air circulates to cool the rotating shaft and sealing positions, isolating high-temperature chamber heat transfer, protecting bearings and seals, and delaying seal aging failure.
Multi-Stage Lip Seal System
Abandoning traditional flat hard seals, the design adopts elastic lip seals with end-face sealing and inter-chamber partition sealing. It self-adapts to micro-deformation of the shaft, isolating intake / exhaust / purge chamber gases, reducing exhaust gas leakage and heat loss.
Design Validation
Through mechanical simulation, multi-condition torque & deformation testing: after optimization, the valve shaft bending deformation is minimal, driving torque is stable, overall air leakage is low, operation is stable, and service life is superior to traditional valves.
Core Function
Precisely distributes airflow to ensure stable RTO regenerative heat storage and release, improves exhaust gas purification efficiency, reduces equipment energy consumption and failure rates. It is the core and critical component of the rotary RTO system.
Waste Heat Recovery Systems
Ever-Power RTO systems recover up to 97% of thermal energy from exhaust gases, converting waste heat into valuable resources through four proven recovery methods — reducing your operating costs while maximizing environmental benefits.

RTO よくある質問
Common questions from potential customers about regenerative thermal oxidizer systems
What is a regenerative thermal oxidizer (RTO) and how does it work?
A regenerative thermal oxidizer (RTO) is an industrial air pollution control device that destroys volatile organic compounds (VOCs), hazardous air pollutants (HAPs), and odors through high-temperature combustion. The system uses ceramic heat exchange media to preheat incoming polluted air before it enters the combustion chamber.
The process works by passing exhaust gases through heated ceramic beds, raising the temperature to 760°C - 820°C (1,400°F - 1,510°F), where VOCs are oxidized into harmless CO₂ and H₂O. The regenerative design recovers up to 95% of thermal energy, making it one of the most efficient oxidation technologies available.
What is the difference between 3-bed RTO and rotary RTO?
3-Bed RTO uses three separate ceramic chambers with switching valves that alternate airflow direction. While effective, it suffers from high exhaust temperatures, higher energy consumption, and the switching valve operates approximately 520,000 times per year, leading to shorter service life.
ロータリーRTO uses a continuous rotating distribution valve with multiple sectors (typically 12 chambers). It maintains exhaust temperatures below 80°C, offers lower energy consumption, reduced operating costs, and the rotary valve operates continuously without switching — resulting in significantly longer service life and superior reliability.
What is the typical operating temperature range for an RTO system?
The standard operating temperature for RTO systems ranges from 760°C to 820°C (1,400°F to 1,510°F). This temperature range ensures complete oxidation of most VOCs and HAPs while maintaining optimal thermal efficiency.
For applications requiring maximum destruction efficiency or handling particularly resistant compounds, the temperature can be increased up to 1,100°C (2,010°F). The residence time is typically maintained at > 5 seconds to ensure complete combustion.
What types of exhaust gases can an RTO treat effectively?
RTO systems are highly versatile and can treat a wide range of exhaust gases containing volatile organic compounds (VOCs), hazardous air pollutants (HAPs), and odorous compounds. Common applications include:
Packaging & printing (solvents, inks), film coating (adhesives, resins), industrial coating (paints, varnishes), chemical processing (organic vapors), asphalt production (hydrocarbon emissions), and petrochemical operations.
RTO is ideal for VOC concentrations ranging from low to high levels up to 10 g/m³. The system can handle air flow rates from 2.4 to 240 standard cubic meters per second, making it suitable for both small and large-scale industrial operations.
How do I choose the right RTO size and configuration for my facility?
Selecting the right RTO requires analysis of several key parameters: exhaust gas flow rate, VOC concentration and composition, required destruction efficiency, available space, and operational requirements.
Our engineering team evaluates your specific application including gas volume (CFM or m³/h), contaminant types, temperature requirements, and regulatory compliance needs. We provide customized solutions ranging from compact units for small operations to large multi-chamber systems for heavy industrial applications.
What is the thermal efficiency of your RTO systems?
Our rotary RTO systems achieve up to 95% thermal efficiency through advanced regenerative heat exchange technology. The ceramic heat exchanger media can be designed for thermal efficiency of up to 97+%, minimizing fuel consumption and operating costs.
VOC destruction efficiency reaches 99.5% or higher, ensuring full compliance with environmental regulations. The combination of high thermal efficiency and destruction efficiency delivers the lowest life-cycle cost compared to other thermal oxidizer technologies.
What is the expected service life of an RTO system and its core components?
Our rotary RTO systems are designed for long-term reliable operation. With over 483 sets successfully running in the field, we have documented performance data showing exceptional durability.
268 sets have accumulated more than 8,000 operating hours, and 358 sets have exceeded 3,000 hours. The rotary distribution valve — the core component — features advanced sealing technology and forced air cooling that extends service life far beyond traditional switching valve designs.
Regular maintenance includes ceramic media inspection, seal replacement, and burner calibration. With proper maintenance, the overall system lifespan exceeds 20 years.
Do you provide installation, commissioning, and after-sales support?
Yes, we provide comprehensive turnkey solutions including system design, manufacturing, installation supervision, commissioning, operator training, and long-term after-sales support. Our technical team has extensive experience with 600+ contracted projects across diverse industries.
We offer online monitoring systems for real-time performance tracking, preventive maintenance programs, and rapid response technical support. 107 sets are currently under our online monitoring and operation service, ensuring optimal performance and minimal downtime.
Our customer return rate demonstrates our service quality: 24 customers have purchased 3+ sets, 62 customers have purchased 2 sets, and 68 customers have entrusted us with their entire plant's environmental solution.
What is the typical payback period for an RTO investment?
The payback period for an RTO system typically ranges from 2 to 5 years, depending on factors such as VOC concentration, operating hours, energy costs, and regulatory compliance requirements.
High VOC concentrations can actually generate excess heat that can be recovered for process heating or other facility uses, further improving the return on investment. Our rotary RTO's superior thermal efficiency (up to 97%) significantly reduces fuel costs compared to conventional thermal oxidizers.
Additionally, avoiding regulatory penalties and maintaining continuous production without shutdowns for compliance issues provides substantial indirect cost savings.

再生熱酸化装置とは？
再生熱酸化物（RTO）は、排出ガスを（破壊）排出ガスに変換し、熱を利用して排出ガスをCO2とH2Oに変換して大気中に放出することにより、揮発性有機化合物（VOC）、有害大気汚染物質（HAP）、悪臭を制御する燃焼装置である。RTOは最大97%の熱効率と99%以上の破壊効率を達成できる。
RTO酸化剤は世界で最も進んだ熱酸化システムの一つと考えられています。他の熱酸化装置と比較して、再生型熱酸化装置（RTOS）の熱効率は最大97%、破壊効率は99%を超える場合があり、最も低いライフサイクルコストで最も高い除去率を実現します。- 業界をリードする構造と設計機能により、優れた性能、大幅に低い運転コスト、業界をリードする信頼性を実現します。
再生熱酸化装置の仕組み
- 再生熱酸化装置（RTOS）は、汚染物質を含んだ空気を過酸化物に通すことで機能する。
- RTOを通る空気の流れは、2つの熱交換器（セラミック誘電体ベッドを含むチャンバー）のうちの1つに空気の流れを導くバルブによって制御される。
- RTOは、熱交換器として少なくとも2つのセラミック誘電体ベッド（サドルおよび/または構造化誘電体ブロック）を備えていなければならない。汚れた空気が第1の媒体床を通過する際、高温のセラミック媒体から熱を吸収し、燃焼室に入る。
- 燃焼室では、汚れた空気が温度（> 1500°F）特定の滞留時間（> 5秒）に保たれる。これにより、VOCとHAPが二酸化炭素と水蒸気に酸化される。
- 高温で清浄な空気は燃焼室を出て、再利用のために熱を吸収する第二のセラミック媒体層に入る。
- 冷却された清浄空気は、大気中に排出される。
バルブが数分ごとに向きを変えるため、流れの方向が逆転し、2つのセラミック媒体層の間で熱伝達が交互に行われる。これが、RTO（再生熱酸化装置）の燃料効率が高く、運転コストが低い理由であり、理想的なVOC削減システムとなっている。

ロータリーRTOの構造
ロータリーRTOは、燃焼室、再生室、ロータリーバルブから構成される。
炉本体は12室に分かれており、入口室が5室、出口室が5室、洗浄室が1室、隔離室が1室となっている。
ロータリーバルブはモーターによって駆動され、連続的かつ均一に回転する。このロータリーバルブの下で、排気ガスは12室間をゆっくりと連続的に切り替わる。基本構造は右図の通り。
一般に、再生室が多いほど浄化効率と熱効率が高くなる。技術の発展に伴い、第三世代のOF RTO、すなわちロータリーRTOが誕生した。
12個の円形再生器を持ち、コンパクトな構造、小さな放熱面積、低エネルギー消費、高い熱効率という利点を持ち、その浄化効率は99.5%まで可能である。
