Thermal Oxidizer System for Wastes Containing Inorganic Salts Aqueous or organic waste streams containing inorganic or organic salts require that the Thermal Oxidizer be down-fired to prevent the accumulation of molten salts in the oxidizer furnace. Aqueous waste streams are injected directly into the Thermal Oxidizer while organic waste may be burnt like a fuel and fired through the burner. Salt or ash laden flue gas from the oxidizer is quenched to its adiabatic saturation temperature by water injection in a quench system located directly below the Thermal Oxidizer. Saturated flue gas from the quench system goes through a particulate matter removal system like a venturi scrubber before being vented to the atmosphere by a stack. Alternatively, a baghouse or an electrostatic precipitate can be used for particulate matter removal. Destruction efficiencies of up to 99.99 percent can routinely be achieved for most waste components. Particulate matter emission rates can vary from as low as 0.005 to as high as 0.08 grains/DSCF. The emission rate to some extent determines the type of particulate removal system necessary.
