RAW and Institutional RAW Treatment and Conditioning

• Modern two-stage incineration plant
• Commissioned: February 2022
• Automated incineration of solid and liquid RAW under a permanently maintained negative pressure regime
  (significant volume and mass reduction).
• Incineration product: ash and fly ash.

Main components:

• Rotary furnace (I. stage thermal treatment)
• thermal reactor (II. stage thermal treatment)
• Dosing of RAW: belt conveyor, screw conveyors, injection
• Refractory pipe, flue gas exchanger, filtration and purification system, continuous emissions measurement, ventilation stack.

Four stages of flue gas purification:

• Neutrec® technology,
• Fabric sleeve filter,
• Dioxin filter,

RAW Incineration Facility PS 06

• Modified: 2012
• Objectives of modification: minimizing total volume of secondary waste, increasing the efficiency of the off-gas filtration process, modification of the incinerator allowing the incineration of spent resin.
• PS 06 is used for treatment of solid and liquid combustible waste containing alfa contamination (while this type of waste is not treated in PS 45 to prevent cross-contamination).

High Force Compacting

• Pressing Power: 20 000 kN
• Reduction Factor 4-8
• Performance: 8-10 200 dm³ drums/hour
• Max. weight of drum: 450kg

Metallic RAW Melting Facility

• Physical process - electric current is used to inductively melt material in a ceramic crucible.
• Product: Melt (ingot), Slag (impurities, waste), Furnace gases (aerosols)
• Furnace output 1,600 kw
• Capacity of 2 tonnes of metal – 5 pcs. of ingots
• Ingot weight - approximately 400 kg

Cementation

• Applied to solid or solidified RAW in drums and/or concrete containers
• Output of Line 1-2 concrete container per shift
• Discontinuous operation

Facility for Processing of used HVAC filters

• Crushing into fractions with dimension of 40 mm x 40 mm in a dual rotor crusher.
• Separation of magnetic and aluminium fragments from the crushed material (placed into 200 litre drums).
• The non-magnetic parts are transferred to a second crusher, where they are fragmented to 20 mm x 20 mm fractions. Secondary separation - for aluminium-containing fractions.
• Feeding and mixing of chemicals to the crushed material.
• Product is further processed by high pressure compacting or incineration in Bohunice RAW Treatment Facility.

Workstation for processing used electrical cables

• Manual decontamination,
• Sorting,
• Separation of external insulation,
• Crushing and separation from recyclable non-ferrous metals.
• Aim: maximization of free release of metallic material into the environment.
• The resulting solid RAW is further processed by high-pressure compacting or incineration in Bohunice RAW Treatment Facility.
