Decontamination system for particulate matter

A decontamination system for particulate matter, said system comprising:

• a fluid treatment chamber, said fluid treatment chamber comprising:
• a inlet port through which contaminated particulate matter is deposited into said fluid treatment chamber;
• a continuous receiving conveyance for receiving deposited contaminated particulate matter and for transporting the particulate matter at least partially through said fluid treatment chamber;
• a fluid applicator for wetting the contaminated particulate matter being carried by said receiving conveyance with a treating fluid that facilitates the separation of contamination from particulate matter;
• an agitating conveyance into which wetted contaminated particulate matter is deposited from said continuous receiving conveyance, said agitating conveyance being at least partially submersed in treating fluid so that a slurry is formed from the combination of contaminated particulate matter and treating fluid;
• a continuous final conveyance located in a lower portion of said fluid treatment chamber, said final conveyance being completely submersed in the treating fluid;
• an exit port through which decontaminated particulate matter passes for removal from the treating fluid;
• and
• a fluid heater system for heat in a treating fluid supplied to said fluid treatment chamber said heater system comprising a direct fluid heater in which treating fluid is exposed directly to heated and an indirect fluid heater said indirect fluid heater having a inner chamber containing heated gas and an outer chamber through which treating fluid is circulated and heated indirectly by the heated gas.
