Efficient Emissions Control
When compliance matters and efficiency counts, Zeeco’s Regenerative Thermal Oxidizers (RTO) deliver. Engineered for industries handling dilute VOC emissions, our RTOs destroy pollutants with exceptional thermal efficiency, all while reducing operating costs and supporting environmental goals.
Why Choose an RTO?
Regenerative Thermal Oxidizers are ideal for handling low-concentration, high-volume air streams where other combustion systems fall short. By capturing and reusing heat, RTOs reduce fuel needs while maintaining destruction removal efficiencies (DRE) of 99% or more.
Key Features and Benefits
- >99% Destruction Removal Efficiency
- 97% Thermal Energy Recovery (TER)
- Low NOx and CO Emissions Limits
- Low-Maintenance Design
- Advanced Controls
- Standardized Modular Configurations (1,000 –100,000 Nm3/hr)
- Multi-chamber Designs
- Custom Configuration
How They Work
Regenerative Thermal Oxidizers destroy VOCs by heating waste gases to 850°–1,150°C (1,562°–2,102°F) in a high-temperature combustion chamber. As the gases pass through ceramic beds before and after combustion, heat is absorbed and then transferred to incoming air, significantly reducing fuel use. A valve system periodically reverses the airflow to maintain up to 97% thermal energy recovery. Once stable temperatures are reached, autothermal operation can begin, eliminating the need for continuous fuel when VOC concentrations are above 3.5g/Nm³, depending on waste gas composition.
Industries That Use RTOs
- 化工和石化工厂
- Paint, Coating, and Printing Facilities
- 半导体与电子制造
- 食品和饮料加工
- Pharmaceuticals & Healthcare Production
VOC Loading Case Study
This table shows three different VOC loading cases using Zeeco’s standard RTO system. At 0% methane, the RTO is designed to achieve the maximum TER, while only requiring 0.191 MMBtu/hr of additional heat to maintain operating temperatures. At 0.267% methane, the system is self-sustaining. At 25% LEL, we optimize the system by customizing the media design and utilizing a hot bypass. This allows Zeeco to offer the same size system for all cases.
