Direct oxidizers use a burner to preheat the incoming process air prior to entering the combustion chamber.
The burner will provide enough energy to heat the process air to the combustion chamber temperature of ~1,400°F. In the combustion chamber, the VOCs within the process exhaust will convert to CO2 and H2O.
This 1,400°F air, now clean, will exhaust to the atmosphere. Direct thermal oxidizers can be designed in a vertical position or horizontal.
Raw gas burners are common to reduce the overall energy consumption. A direct thermal oxidizer can be a low-cost solution for many applications.
The TANN Advantage
- Custom and standard direct oxidizer designs (5 SCFM to 20,000 SCFM)
- Vertical or horizontal designs
- 99%+ destruction efficiencies
- Heat recovery options to utilize stack exhaust energy
- Best warranty in the industry
Applications
- Low Operating Hours – Low operating hours can keep the overall operating costs down.
- Corrosive Environment – The oxidizer can be manufactured from corrosive resistant steels. The small footprint can keep the initial cost low.
- High Solvent Concentration – Direct oxidizers are able to handle very high solvent concentrations, where other oxidizer technologies cannot.
- Low Flow Rate – Direct oxidizers are common where the flow rate from the process exhaust is low, 5 to 1,000 SCFM. This low exhaust rate will keep the energy usage down and make the direct oxidizer the most economical solution.
