After passing through a screening device, the contaminated soil is conveyed to the top of the KLEAN MACHINE where it is spread out using a unique auger system over an eight foot length. The soil then cascades like a waterfall through propane (or natural gas) flame where the contaminates are vaporized and driven off to the baghouse. There are three such chambers to assure all the hydrocarbon contaminates are vaporized. Cleaned soil then proceeds through a dust control system and is conveyed away from the KLEAN MACHINE where it may be tested and used immediately as backfill or for other disbursement.
The gaseous vapors pass through a baghouse by an induced draft fan where fine dust particulate are removed and sent back to the processor. Gasses then pass into the Thermal Oxidizer where they are heated to a temperature approaching 1500°F. The Thermal Oxidizer thoroughly destroys the hydrocarbon contaminates. Exhaust from the Thermal Oxidizer is then treated, cooled and returned to the atmosphere at air quality levels far below accepted standards for most jurisdictions.
