ROTRotating incinerator with a patented

”near to zero” emission filter

All data within this presentation is according to the European norms 2000/76/CEE and the future emission limits (2012).

Total Waste TreatmentTechnology ROT

Type of furnace

CC-ROT (counter current)

• the waste is moving downwards in the opposite direction of the furnace hot-gas


Type of waste

• All types of waste– very low calory waste (sludge), – low calory waste (municipal waste, garbage)– high calory waste (hospital waste, industrial waste)


Loading system

• collected and transported to location by trucks • bunker bridge-crane • municipal bulk refuse is loaded automatically • Manual loading is always possible • upper accumulation hopper (trash container)


Furnace & combustion system

Rotating pyrolitic furnace• 1st stage

– Starved air condition– Sterile inert ash and a pyrolitic gas– Sufficiently slow– Cool water injection– Maintaining ashes to 850°-900°– Ash varies around 3%– Fully automated burner– Slight negative pressure


Furnace & combustion system

• Post combustor or “After burner”– Gasses mixed with fresh combustion air– Completely refractory lined (resistent to heat)– Auxiliary burners – Electric interlock– Heated by the pyrolitic combustible gas– Temperature 950° - 1100°– Large manholes & sight glass– Secundary air fan V02 (oxygen)– System control logic


Chimney ..............

• Natural Drift Chimney– Mounted directly over the top of the post combustion chamber top

(25m top)– Used during the heat-up phase and in case of an emergency boiler

emergency shutdown

• Forced Draft Chimney– Forced evacuation of the cleaned flue gas into the atmosphere

(minimum 30m height)


High pressure boiler & heat recuperation system

• needed to cool down the flue gas temperature• used to produce electric energy and heat

• It consists of a high pressure, high temperature boiler


Flue gas standard dry cleaning system (AFS)

• No liquid discharge• To render the emissions to comply fully with European

standards.• Optional: Retrofit dry Super Depuration patented system

– This reduces substantially the emission levels below the limits of the EEC norms.


Supply

• Included– The project (design)

• Excluded– Buildings

– Materials (unless stated differently in the contract)


Summary

• Complete incineration (99,99%)• Complete ash inertisation

– removing toxics & physical binding

• Minimum ash quantity (3%)• Great loading flexibility• Precise combustion control• Low working cost• Very high economical profit

– electric energy & heat

• Long duration of plant
