Three-Bed Regenerative Thermal Oxidizer

Three-Bed Regenerative Thermal Oxidizer

A high-heat-recovery oxidizer for continuous treatment of medium-to-high VOC loads and changing solvent mixtures.

Equipment configuration

Designed around actual process conditions

Three regenerative chambers alternate between inlet preheating, oxidation and heat recovery. The arrangement supports stable continuous operation, low purge loss and useful heat recovery for drying or other plant duties.

Treatment principle

How it works

Ceramic media preheats the incoming exhaust. VOCs are oxidized in the combustion chamber, then outgoing clean gas transfers heat to another ceramic bed before discharge.

  3. 03Oxidize VOCs at controlled temperature
  4. 04Recover outlet heat and discharge

Selection cautions
  • Final sizing depends on solvent chemistry, LEL margin and concentration profile.
  • Halogenated, sulfur-bearing, silicon-bearing or corrosive streams require dedicated review.

Typical pollutants

  • Alkanes and olefins
  • Alcohols and ketones
  • Ethers and esters
  • Aromatic and mixed solvents

Engineering features

  • Sequenced three-chamber operation
  • PLC monitoring and safety interlocks
  • Secondary waste-heat recovery options
  • Integration with coating and drying lines

Available options

  • Hot-air recovery
  • Hot-water or thermal-oil recovery
  • Upstream scrubber or filtration
