- Direct Fired Thermal Oxidizers



When you have issues of high calorific value waste gas or a liquid stream then the Process Combustion’s Direct Fired Thermal Oxidisers meet the most stringent requirements of the European Solvents Emissions Directive (SED) and the UK’s Waste Incineration Directive. Designed and built to client’s own specific standards Process Combustion’s solutions ensure that very high concentrations of volatile organic compounds (VOCs) in waste and gas streams can be dealt with effectively and safely. In some cases waste streams can be cleverly injected through the burner system and utilised as a fuel. Added energy saving equipment like waste heat boilers and secondary heat recovery systems can be included to recover heat and be introduced back into the process.


Direct fired thermal oxidisers produced by Process Combustion Ltd are most effective when there is a high calorific value waste gas or liquid stream that needs to be treated. Process Combustion Ltd can design and build these units to help meet the most stringent requirements of the European Solvent Emissions Directive (SED) and the United Kingdom Waste Incineration Directive (WID).


Key benefits include:

  • Can handle very high VOC concentrations
  • Industry beating extremely high VOCs destruction efficiency – up to 99.95%
  • Reacts speedily to high peak concentrations
  • Can be designed to provide constant heat recovery to be used elsewhere in the process.
