Direct Fired Thermal Oxidizers (which do not utilize primary forms of heat recovery to lower fuel consumption) are the simplest straight forward type of thermal oxidizer. Direct Fired Thermal Oxidizers are also known as Afterburners, DFTO’s, Fume Incinerators, and Enclosed Flares. Over the years, advances in heat recovery equipment has reduced the applications that utilize Direct Fired Oxidizers.
However, the simplicity of operation, ability to achieve very high DRE (destruction removal efficiency), ability to be online and accepting process quickly, and tolerance for varying VOC loadings have opened new opportunities for direct fired units. Air Clear has recently supplied Direct Fired Thermal Oxidizers for applications in the Oil and Gas industry (include truck and terminal loading facilities), Ethanol Plants, Carbon Fiber, Coating and Chemical Processing.
Also, our proprietary design for Renewable Natural Gas or Landfill Gas to pipeline grade uses our advanced burner systems to process waste streams which are made up of 25% Methane. Air Clears’ tank degassing/cleaning oxidizers (mobile or stationary) achieve 99.99% DRE! When the utilization of waste heat recovery is added to the system making a DFTO a cost effective solution.
