What is a thermal oxidizer?
A thermal oxidizer (also known as thermal oxidiser, fume incinerator or thermal incinerator) is a type of air pollution control equipment used in industrial processes to reduce emissions of volatile organic compounds (VOCs), odors, harmful air pollutants (HAPs), and other greenhouse gases (GHG) before releasing them into the atmosphere.
How does a thermal oxidizer work?
Using extreme high temperatures (1500°F) to trigger a combustion reaction, the VOCs & air pollutants undergo thermal oxidization, transforming the organic solvents into CO2 (carbon dioxide) and H2O (water).
Similar to an incinerator, a thermal oxidizer is an EPA-approved device to treat VOCs, odors, HAPs, contaminated gases, and aerosolized solvents.
Types of thermal oxidizers:
Regenerative Thermal Oxidizer(RTO) The most common type of oxidizers, the RTO uses ceramic media to capture and recycle waste heat, offering 95% thermal efficiency. The RTO is the most expensive type of thermal oxidizer, but offers the lowest energy costs.
Gas Flare (Vapor Combustor)While not technically a type of thermal oxidizer, the flare is similar to the direct-fired oxidizer but it does not require supplemental natural gas. Flares are used on very high concentration VOC gas streams (over 3-5% of LEL).
Catalytic Thermal Oxidizer (CATOX)This type uses a metal catalyst to speed along the VOC's decomposition reaction. The main advantage of catalytic thermal oxidizers is that they can operate at much lower temperatures of 800°F-900°F instead of 1400°F-1500°F.
Thermal Oxidizer Efficiency
*A Rotary RTO or Three-chamber RTO will be the most effective at removing odor compounds.
*Note: only direct-fired and recuperative oxidizers are effective at treating particulates.
